CAPN2
Function
Calcium-regulated non-lysosomal thiol-protease which catalyzes limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Proteolytically cleaves MYOC at 'Arg-226' (PubMed:17650508). Proteolytically cleaves CPEB3 following neuronal stimulation which abolishes CPEB3 translational repressor activity, leading to translation of CPEB3 target mRNAs (By similarity).
Sequence Similarities
Belongs to the peptidase C2 family.
Tissue Specificity
Ubiquitous.
Cellular localization
- Cytoplasm
- Cell membrane
- Translocates to the plasma membrane upon Ca(2+) binding.
