KLK14

A gene on chromosome 19q13.3-q13.4 that encodes a serine endopeptidase with a trypsin- and chymotrypsin-like substrate specificity, which may: activate/inactivate proteinase-activated receptors F2R, F2RL1 and F2RL3, as well as other kallikreins (e.g., KLK1, KLK3, KLK5 and KLK11); liquefy seminal clot by cleaving semenogelins SEMG1 and SEMG2 and activating KLK3; cleave desmoglein DSG1, resulting in shedding of superficial keratinocytes from the skin surface; and play a role in tumour progression by affecting growth, invasion and angiogenesis.

Very low PSA concentrations and deletions of the KLK3 gene

KLK11, KLK13, and KLK14 were measured as previously described (18, 19) (see Supplemental Data section in the online Data Supplement).

The KLK8 mRNAs were considered alone or as a ratio with the KLK5, KLK6, KLK7, KLK10, KLK11, KLK13, or KLK14 mRNA in the same samples.

KLK5, KLK13, and KLK14 may also contribute to tumor cell invasion via degradation of extracellular matrix components (37-39).

Alternative splicing variant of kallikrein-related peptidase 8 as an independent predictor of unfavorable prognosis in lung cancer

Highest concentrations of KLK14 were found in fetal skin and cartilage.

KLK14 was most abundant in CVF, with lower concentrations in seminal plasma, amniotic fluid, and saliva.

Previously, several other kallikreins, including KLK4, KLK5, KLK6, KLK7, KLK8, KLK9, KLK10, KLK11, KLK14, and KLK15, have been associated with various forms of malignancy and especially cancers of the ovary, breast, prostate, and testis [reviewed in Refs.

Telomeric to the last kallikrein gene, KLK14, lies another nonkallikrein gene, Siglec 9, a member of the Siglec multigene family (9,10).

It is possible that in the future, new members of this gene family may be identified, either centromeric to KLK1 or telomeric to KLK14.
