PhysiologyMay play a role in desquamation of stratum corneum. Enhanced expression in inflammatory skin disease may be of etiological significance (Hansson et al., 2002).
Pharmaceutical relevanceA genetic association between an AACC insertion in the 3"UTR of the stratum corneum chymotryptic enzyme gene and atopic dermatitis has been reported by Vasilopoulos et al., 2004, suggesting that the enzyme could have an important role in the development of atopic dermatitis.
