Calpain-12 (CAPN12) is a member of the calpain family of calcium-dependent cysteine proteases, which play critical roles in modulating cellular processes such as cytoskeletal remodeling, signal transduction, and apoptosis. Unlike many calpains with broad tissue distribution, CAPN12 displays more restricted expression, primarily observed in epithelial tissues, particularly the skin and hair follicles. This tissue specificity suggests it may have specialized functions in epidermal homeostasis, barrier formation, or hair cycle regulation. Structurally, CAPN12 contains conserved domains typical of calpains, including a protease core and calcium-binding regions, but lacks certain regulatory domains found in other family members, possibly implying unique activation mechanisms or substrate preferences.
Recombinant human CAPN12 protein is produced using genetic engineering techniques, enabling studies on its enzymatic activity, substrate interactions, and regulatory pathways. Its recombinant form allows researchers to investigate its potential role in skin disorders, wound healing, or hair growth abnormalities. However, CAPN12 remains one of the less-characterized calpains, with limited data on its precise physiological substrates or disease associations. Recent interest has emerged in exploring its involvement in epithelial-specific pathologies and as a biomarker for certain dermatological conditions. Further research is needed to elucidate its biological significance and therapeutic potential in tissue-specific contexts.
