KLK4

A gene on chromosome 19q13.41 that encodes a serine protease expressed in the prostate.

Molecular pathology

Low concentrations of KLK4 were found in a wide variety of tissues, adult and fetal.
KLK4 was primarily found in seminal plasma, with lower concentrations in breast milk and urine.
6] Human genes: KLKI, kallikrein 1, renal/pancreas/salivary; KLK2, kallikrein 2, prostatic; KLK3, kallikrein 3 (prostate-specific antigen); and KLK4, kallikrein 4 (prostase, enamel matrix, prostate).
All of the above studies have examined total KLK4 mRNA expression.
In contrast to the multiple studies examining KLK4 at the mRNA level, only 3 published studies have investigated the KLK4 gene product (the hK4 protein).

KLK7 is up-regulated in ovarian cancer (62), and KLK4 and KLK5 are indicators of poor prognosis of ovarian cancer (63-65).
An alternatively spliced variant of KLK4 expressed in prostatic tissue.
Because the open reading frame of KLK4 predicts that its first 26 N-terminal amino acids are the signal peptide, we expected that the 224-amino acid mature enzymatic form would be a secreted protein (3, 5, 9).
After the PCRs were completed, 15 [micro]L of the 278-bp KLK4 product was visualized by staining with ethidium bromide on 2% agarose gels.
