Description…
The glandular kallikreins are a distinct group of serine proteases with molecular masses of 25,000 to 40,000. 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. Several human kallikrein genes have been isolated. hK4 is expressed in the prostate.

Overview
Kallikreins (KLKs) are highly conserved serine proteases that play key roles in a variety of physiological and pathological processes. KLK4 is regulated by androgens and is highly specific to prostate for expression. hK4 is intracellularly localized. KLK4 is predominantly expressed in the basal cells of the normal prostate gland and overexpressed in prostate cancer. hK4 has a unique structure and function compared with other members of the KLK family and may have a role in the biology and characterization of prostate cancer.
Performance Comment
hK2, hK4 and hK11 do not distinguish cases from controls in these populations.
