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. Expression of this gene is regulated by steroid hormones and may be useful as a marker for breast cancer. [provided by RefSeq, Jan 2017]
A study in humans demonstrated that the KLK13 is a vaginal fluid-specific mRNA marker used in a multiplex RT-PCR assay for forensic identification, showing a sensitivity of 97.2% in vaginal fluid samples [Akutsu et al. DOI:10.1016/j.legalmed.2020.101715]. Subsequent research confirmed its high specificity (1.00) and sensitivity (0.89) for vaginal fluid, with positive detection maintained in 1:5 diluted samples and in aged stains stored for up to 8.5 years, establishing it as a reliable component of a comprehensive body fluid identification procedure [Akutsu et al. DOI:10.1016/j.legalmed.2022.102087].
