Summaries for KLK4 Gene

Entrez Gene Summary for KLK4 Gene

  • 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]

GeneCards Summary for KLK4 Gene

KLK4 (Kallikrein Related Peptidase 4) is a Protein Coding gene. Diseases associated with KLK4 include Amelogenesis Imperfecta, Type Iia1 and Amelogenesis Imperfecta Hypomaturation Type. Among its related pathways are Collagen biosynthesis and modifying enzymes and MSP-RON Signaling. GO annotations related to this gene include serine-type endopeptidase activity and serine-type peptidase activity. An important paralog of this gene is KLK12.

UniProtKB/Swiss-Prot for KLK4 Gene

  • Has a major role in enamel formation (PubMed:15235027). Required during the maturation stage of tooth development for clearance of enamel proteins and normal structural patterning of the crystalline matrix (By similarity).
