FunctionMay catalyze the degradation of intercellular cohesive structures in the cornified layer of the skin in the continuous shedding of cells from the skin surface. Specific for amino acid residues with aromatic side chains in the P1 position. SCCE cleaves insulin B chain at '6-Leu- -Cys-7', '16-Tyr- -Leu-17', '25-Phe- -Tyr-26' and '26-Tyr- -Thr-27'. Could play a role in the activation of precursors to inflammatory cytokines.
Tissue specificityAbundantly expressed in the skin and is expressed by keratinocytes in the epidermis. Also expressed in the brain, mammary gland, cerebellum, spinal cord and kidney. Lower levels in salivary glands, uterus, thymus, thyroid, placenta, trachea and testis. Up-regulated in ovarian carcinoma, especially late-stage serous carcinoma, compared with normal ovaries and benign adenomas (at protein level).
Sequence similaritiesBelongs to the peptidase S1 family. Kallikrein subfamily. Contains 1 peptidase S1 domain.
Cellular localizationSecreted. In ovarian carcinoma, secreted and also observed at the apical membrane and in cytoplasm at the invasive front.
