ID:CAN1_HUMAN DESCRIPTION: RecName: Full=Calpain-1 catalytic subunit; EC=3.4.22.52; AltName: Full=Calcium-activated neutral proteinase 1; Short=CANP 1; AltName: Full=Calpain mu-type; AltName: Full=Calpain-1 large subunit; AltName: Full=Cell proliferation-inducing gene 30 protein; AltName: Full=Micromolar-calpain; Short=muCANP; FUNCTION: Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. CATALYTIC ACTIVITY: Broad endopeptidase specificity. COFACTOR: Binds 4 calcium ions. ENZYME REGULATION: Activated by micromolar concentrations of calcium and inhibited by calpastatin. SUBUNIT: Forms a heterodimer with a small (regulatory) subunit (CAPNS1). INTERACTION: P40763:STAT3; NbExp=2; IntAct=EBI-1542113, EBI-518675; SUBCELLULAR LOCATION: Cytoplasm. Cell membrane. Note=Translocates to the plasma membrane upon Ca(2+) binding. TISSUE SPECIFICITY: Ubiquitous. PTM: Undergoes calcium-induced successive autoproteolytic cleavages that generate a membrane-bound 78 kDa active form and an intracellular 75 kDa active form. Calpastatin reduces with high efficiency the transition from 78 kDa to 75 kDa calpain forms. SIMILARITY: Belongs to the peptidase C2 family. SIMILARITY: Contains 1 calpain catalytic domain. SIMILARITY: Contains 4 EF-hand domains.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
