Kallikrein-3 or KLK3 is a serine proteases subgroup, enzymes can cleave peptide bonds. KLK3 is found in the prostate and may be hold accountable to the regulation of semen liquefaction via seminogelin hydrolysis. The protein is expressed in low concentrations in men with healthy prostates serum. When elevated quantities are found it may show prostate cancer or different prostate disorders such as prostatitis and benign prostatic hyperplasia.
KLK3 Human Recombinant produced in HEK cells is a single, glycosylated, polypeptide chain (18-261 a.a) containing a total of 250 amino acids, having a molecular mass of 27.6kDa.KLK3 is fused to a 6 amino acid His-tag at C-terminus,and is purified by proprietary chromatographic techniques.
| UniProt Protein Function: | PSA: Hydrolyzes semenogelin-1 thus leading to the liquefaction of the seminal coagulum. Forms heterodimer with SERPINA5. Inhibited by SERPINA5. Activity is strongly inhibited by Zn2+, 100 times more abundant in semen than in serum. This inhibition is relieved by exposure to semenogelins, which are avid zinc binders. Belongs to the peptidase S1 family. Kallikrein subfamily. |

| NCBI Summary: | 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. Its protein product is a protease present in seminal plasma. It is thought to function normally in the liquefaction of seminal coagulum, presumably by hydrolysis of the high molecular mass seminal vesicle protein. Serum level of this protein, called PSA in the clinical setting, is useful in the diagnosis and monitoring of prostatic carcinoma. Alternate splicing of this gene generates several transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008] |
