KLK1（kallikrein 1），癌症关联基因，基因ID：3816，激肽释放酶是丝氨酸蛋白酶的一个亚群，具有多种生理功能。越来越多的证据表明，许多激肽释放酶与癌症的发生有关，有些激肽释放酶有可能成为新的癌症和其他疾病的生物标志物。这个基因是位于19号染色体上的15个激肽释放酶亚家族成员之一。这种蛋白质在功能上是保守的，能够从低分子量的激肽原中释放血管活性肽Lys缓激肽[由RefSeq提供，2008年7月]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. This protein is functionally conserved in its capacity to release the vasoactive peptide， Lys-bradykinin， from low molecular weight kininogen. [provided by RefSeq， Jul 2008]。
