KLK7

A gene on chromosome 19q13.3 that encodes a serine protease that catalyses the degradation of intercellular cohesive structures in the cornified layer of the skin during the normal shedding of cells from the skin surface. KLK7 may play a role in activating precursors of inflammatory cytokines.

Specifically expressed in keratinizing squamous epithelia, HSCCE is suggested to play a role in the turnover and/or formation of the stratum corneum (2).
Because the HSCCE gene (a) is located next to other members in the human kallikrein family, (b) has the same genomic organization and intron phase as other members of this family and (c) has significant homology to other members of the family in both the DNA and amino acid sequences (7), HSCCE is now considered to be a member of the human kallikrein family and has been given a new name, KLK7 for the gene and human kallikrein 7 (hK7) for the protein (8).
