About KLK4

Cytogenetic location: 19q13.41 Genomic coordinates (GRCh38): 19:50,906,351-50,911,395 (from NCBI)

This gene has 8 transcripts (splice variants), 105 orthologues, 12 paralogues and is associated with 2 phenotypes. Restricted expression toward prostate (RPKM 123.8).

Summary

Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel Cancer and Other disease biomarkers. This gene is one of the fifteen Kallikrein subfamily members located in a cluster on chromosome 19. In some tissues its expression is hormonally regulated. The expression pattern of a similar mouse protein in murine developing teeth supports a role for the protein in the degradation of enamel proteins. Several transcript variants encoding different proteins have been found for this gene. [provided by RefSeq, Dec 2014]
