ID:CAN8_HUMAN DESCRIPTION: RecName: Full=Calpain-8; EC=3.4.22.53; AltName: Full=New calpain 2; Short=nCL-2; AltName: Full=Stomach-specific M-type calpain; FUNCTION: Calcium-regulated non-lysosomal thiol-protease. Involved in membrane trafficking in the gastric surface mucus cells (pit cells) and may involve the membrane trafficking of mucus cells via interactions with coat protein. Proteolytically cleaves the beta- subunit of coatomer complex (By similarity). CATALYTIC ACTIVITY: Broad endopeptidase specificity. COFACTOR: Binds 2 calcium ions (Potential). SUBUNIT: Monomer and homooligomer. Interacts with COPS1/GPS1, COPB1, EYA2, NME2, NME4 and TOMM70A (By similarity). SUBCELLULAR LOCATION: Cytoplasm (By similarity). Golgi apparatus (By similarity). TISSUE SPECIFICITY: Stomach. DOMAIN: The domain III mediates oligomerization (By similarity). PTM: Undergoes autolytic cleavage between Ala-5 and Ala-6 which gives rise to fragments extending from Ala-6 to the C-terminus, Ala-6 to the EF-hand 2 domain and from Ala-6 to the beginning of domain III (By similarity). SIMILARITY: Belongs to the peptidase C2 family. SIMILARITY: Contains 1 calpain catalytic domain. SIMILARITY: Contains 3 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.
