KLK15

KLK15

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.

(12) identified 555 polymorphic loci within the region containing KLK3 and the neighboring genes KLK15 and KLK2, including 116 novel SNPs, 182 novel insertion-deletion (indel) polymorphisms, and 257 previously described loci.
Individual S7 showed deletion of all KLK3 exons (see Appendix 5 in the online Data Supplement) and the neighboring gene KLK15 (upstream ofKLK3).
KLK15 (kallikrein-related peptidase 15), a cancer-related serine protease gene belonging to the same gene family as PSA (40),is identified among the most probable predicted targets of miR-224 (31, 36).

KLK15 is most abundant in the breast, adult and fetal skin, and fetal stomach.
KLK15 was found primarily in CVF and breast milk, with lower concentrations in seminal plasma, breast cancer cytosol, and saliva.
The human tissue kallikrein family includes 15 genes (KLK1 to KLK15) [6] clustered in tandem on chromosome 19813.4.
The androgen-regulated gene human kallikrein 15 (KLK15) is an independent and favourable prognostic marker for breast cancer.
When we performed PCR on 36 healthy human tissue samples, we observed a second band, higher than the one expected for the classical form for the genes KLK1, KLK2, KLK5, and KLK15. After cloning and sequencing these bands, we verified that they represent splice variants with retained intron III (Fig.
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.

If new kallikrein genes are identified in this locus, they will be numbered sequentially, starting with KLK15. No other kallikrein-like or other genes map between the 14 kallikrein genes described by Diamandis et al.
