Protein Name: Calpain-2 catalytic subunit

UniprotKB/SwissProt ID: Q07009 (Q07009)

Gene Name: Capn2

Organism: Rattus norvegicus (Rat)

Function: Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Proteolytically cleaves MYOC at 'Arg-226'. Proteolytically cleaves CPEB3 following neuronal stimulation which abolishes CPEB3 translational repressor activity, leading to translation of CPEB3 target mRNAs

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm. Cell membrane
