  • Alzheimers and calpain protease, PMAP Proteolytic cleavage of p35 by calpain-1 produces p25, which accumulates in the brains of patients with Alzheimer's disease Nature. 2000 May 18;405(6784) Cyclin-dependent kinase 5 (cdk5), a multi-functional kinase, and its neuron-specific activator p35 are required for neurite outgrowth and cortical lamination. Proteolytic cleavage of p35 produces p25, which accumulates in the brains of patients with Alzheimer's disease. Conversion of p35 to p25 causes prolonged activation and mislocalization of cdk5 and the hyperphosphorylates tau, leading to the formation of paired helical filaments and promotes apoptosis. In cultured primary cortical neurons, excitotoxins, hypoxic stress and calcium influx induce the production of p25. In fresh brain lysates, addition of calcium can stimulate cleavage of p35 to p25. Specific inhibitors of calpain1, effectively inhibit the calcium-induced cleavage of p35. In vitro, calpain1 directly cleaves p35 to release a fragment with relative molecular mass 25000. Application of the amyloid beta-peptide A beta induces the conversion of p35 to p25 in primary cortical neurons. Inhibition of cdk5 or calpain activity reduces cell death in A beta-treated cortical neurons. These observations indicate that cleavage of p35 to p25 by calpain may be involved in the pathogenesis of Alzheimer's disease. GSK3B also phosphoryklates tau but does not induce hyperphosphorylation in response to calpain activating stimuli. Additionally down ...

  • Anthrax Lethal proteaase X-ray, PMAP Anthrax lethal factor (LF) acts as a Zn2+-dependent endoprotease that snips off the N-terminus of mitogen-activated protein kinase kinases (MAPKK). Anthrax toxin refers to three proteins secreted by virulent strains of the bacterium Bacillus anthracis. These three proteins act together in a synergistic way in which they are endocytosed and translocated into the cytoplasm of a macrophage, where it disrupts cellular signaling and induces cell death, allowing the bacteria to evade the immune system. The disease known as anthrax is caused by Bacillus anthracis, a spore-forming bacterium whose pathogenesis is primarily the result of a tripartite toxin. This toxin is composed of three proteins the protective antigen (PA), the edema factor (EF) and the lethal factor (LF). These proteins work together to enter a cell and disrupt the signaling pathways, eventually leading to apoptosis. The molecular actions of PA, EF, and LF also provide a model biochemical system that demonstrates a variety of structure-function relationships seen in biochemistry.

  • Apoptosis & Caspase 7 (1), PMAP Caspase-7 is a member of the caspase (cysteine aspartate protase) family of proteins, and has been shown to be an executioner protein of apoptosis. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing by upstream caspases (caspase-8, -9)at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme in the form of a heterotetramer. The precursor of this caspase is cleaved by caspase 3, caspase 10, and caspase 9. It is activated upon cell death stimuli and induces apoptosis.

MMPs form a multigenic family of proteolytic, zinc-dependent enzymes, with 26 members described until present, displaying multidomain structures and substrate specificities. MMPs are involved in both the turnover and degradation of extracellular matrix (ECM) proteins and in the processing, activation, or deactivation of a variety of soluble factors. They are regulated at the level of transcription, activation of the precursor zymogens, and inhibition mainly by tissue inhibitors of metalloproteinases (TIMPs).

  • Alzheimer's proteases: by PMAP Gamma secretase is a multi-subunit protease complex, itself an integral membrane protein, that cleaves single-pass transmembrane proteins at residues within the transmembrane domain. The most well-known substrate of gamma secretase is amyloid precursor protein, a large integral membrane protein that, when cleaved by both gamma and beta secretase, produces a short 39-42 amino acid peptide called amyloid beta whose abnormally folded fibrillar form is the primary component of amyloid plaques found in the brains of Alzheimer's disease patients. Gamma secretase is also critical in the related processing of the Notch protein.

  • Proteosomes Proteasomes are large protein complexes inside all eukaryotes and archaea, as well as in some bacteria. In eukaryotes, they are located in the nucleus and the cytoplasm.The main function of the proteasome is to degrade unneeded or damaged proteins by proteolysis, a chemical reaction that breaks peptide bonds. Enzymes that carry out such reactions are called proteases. Proteasomes are a major mechanism by which cells regulate the concentration of particular proteins and degrade misfolded proteins. The degradation process yields peptides of about seven to eight amino acids long, which can then be further degraded into amino acids and used in synthesizing new proteins.Proteins are tagged for degradation by a small protein called ubiquitin. The tagging reaction is catalyzed by enzymes called ubiquitin ligases. Once a protein is tagged with a single ubiquitin molecule, this is a signal to other ligases to attach additional ubiquitin molecules. The result is a polyubiquitin chain that is bound by the proteasome, allowing it to degrade the tagged protein

  • Apoptosis & Caspase 8 - PMAP Caspase 8 is member of the cysteine-aspartic acid protease (caspase) family. The NH2-terminal region of caspase-8 contains two death effector domains (DEDs), through which it binds the DED of Fas-associated death domain (FADD). The COOH-terminal region of caspase-8 is related to the interleukin-1beta converting enzyme (ICE) family of proteases. FADD mediates the recruitment of caspase-8 to tumor necrosis factor receptor 1 (TNF-R1), where caspase-8 becomes activated, presumably by self-cleavage, and in turn initiates a proteolytic cascade that ultimately leads to apoptosis. Two important examples of the direct initiation of apoptotic mechanisms in mammals include the TNF-induced (tumour necrosis factor) model and the Fas-Fas ligand-mediated model, both involving receptors of the TNF receptor (TNFR) family coupled to extrinsic signals. TNF is a cytokine produced mainly by activated macrophages, and is the major extrinsic mediator of apoptosis. Most cells in the human body have two receptors for TNF TNF-R1 and TNF-R2. The binding of TNF to TNF-R1 has been shown to initiate the pathway that leads to caspase activation via the intermediate membrane proteins TNF receptor-associated death domain (TRADD) and Fas-associated death domain protein (FADD).

  • Attacking Tumor Vasculature, PMAP Angiogenesis is a fundamental step in the transition of tumors from a dormant state to a malignant state. Therapeutic angiogenesis is the application of specific compounds which may inhibit or induce the creation of new blood vessels in the body in order to combat disease. The presence of blood vessels where there should be none may affect the mechanical properties of a tissue, increasing the likelihood of failure. The absence of blood vessels in a repairing or otherwise metabolically active tissue may retard repair or some other function. Several diseases (eg. ischemic chronic wounds) are the result of failure or insufficient blood vessel formation and may be treated by a local expansion of blood vessels, thus bringing new nutrients to the site, facilitating repair. Other diseases, such as age-related macular degeneration, may be created by a local expansion of blood vessels, interfering with normal physiological processes.

Caspases exist as inactive proenzymes that undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein cleaves and activates caspases 6, 7, and 9; and the protein itself is processed by caspases 8, 9, and 10. It is the predominant caspase involved in the cleavage of amyloid-beta 4A precursor protein, which is associated with neuronal death in Alzheimer's disease.

  • Prostate Cancer & Endothelin: PMAP Endothelin-converting enzyme-1 is involved in the proteolytic processing of endothelin-1 (EDN1; MIM 131240), -2 (EDN2; MIM 131241), and -3 (EDN3; MIM 131242) to biologically active peptides. http Prostate cancer is a disease in which cancer develops in the prostate, a gland in the male reproductive system. It occurs when cells of the prostate mutate and begin to multiply out of control. These cells may spread (metastasize) from the prostate to other parts of the body, especially the bones and lymph nodes. Prostate cancer may cause pain, difficulty in urinating, erectile dysfunction and other symptoms. Endothelins are proteins that constrict blood vessels and raise blood pressure. They are normally kept in balance by other mechanisms, but when they are over-expressed, they contribute to high blood pressure (hypertension) and heart disease. The ubiquitous distribution of endothelin peptides and receptors implicates its involvement in a wide variety of physiological and pathological processes in the body. Among numerous diseases potentially occurring from endothelin dysregulation are: several types of cancer; cerebral vasospasm following subarachnoid hemorrhage; arterial hypertension and other cardiovascular disorders; pain mediation

  • protein synthesis Protein synthesis is the process in which cells build proteins. The term is sometimes used to refer only to protein translation but more often it refers to a multi-step process, beginning with amino acid synthesis and transcription of nuclear DNA into messenger RNA, which is then used as input to translation. The cistron DNA is transcribed into a variety of RNA intermediates. The last version is used as a template in synthesis of a polypeptide chain. Proteins can often be synthesized directly from genes by translating mRNA. When a protein needs to be available on short notice or in large quantities, a protein precursor is produced. A proprotein is an inactive protein containing one or more inhibitory peptides that can be activated when the inhibitory sequence is removed by proteolysis during posttranslational modification. A preprotein is a form that contains a signal sequence (an N-terminal signal peptide) that specifies its insertion into or through membranes; ie, targets them for secretion
