Summary
Protein Function
Calpain-1 catalytic subunit, encoded by the CAPN1 gene, is one type of non-lysosomal, intracellular cysteine proteases. And Calpain-1 is calcium-activated neutral protease. The mammalian calpains include ubiquitous, stomach-specific, and muscle-specific proteins. The ubiquitous enzymes consist of heterodimers with distinct large, catalytic subunits associated with a common small, regulatory subunit. (From Wikipedia)
Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Broad endopeptidase specificity. (From Uniprot)
Cys Function & Property
Cys115 is one of the active sites of Cathepsin H, which is very close to His272 and Asn296 in space. These three residues formed a typical catalytic triad motif.
- Hydrophobic property:
- SASA：
- Cys115: 12.816 A^2
