背景信息

KLK9, or kallikrein-related peptidase 9, is a member of the human kallikrein-related peptidases family, which is the largest family of secreted serine proteases. These enzymes have diverse expression patterns and physiological roles, and their aberrant activity has been linked to various pathologies such as respiratory diseases, neurodegeneration, skin-barrier dysfunction, and cancer. The serum level of KLK9 has also been suggested to have the potential to be used as a biomarker for asthma. The KLK9 gene was also found to be regulated by steroid hormones, mainly estrogens and progestins, in cancer cell lines.
