KLK 11 is a cell-surface-expressed type II transmembrane serine protease and was identified as one of the most highly upregulated genes in prostate cancer. KLK 11 protein expression was highest at sites of bone metastasis and in late-stage primary tumor, suggesting a role in tumor progression. In accordance, in vivo studies demonstrated that overexpression of KLK 11 led to tumor progression and metastasis. As KLK 11 expression correlates well with prostate cancer progression, it was proposed as a diagnostic marker and target for prostate cancer therapy.
