Background
KLK14, or Kallikrein-14, is a protein-coding gene that belongs to the kallikrein family of secreted serine proteases. Activation of KLK14 is mediated by KLK5, and once activated, KLK14 further amplifies the activity of KLK proteases through a positive feedback loop by cleaving pro-KLK5, which is a central player in the KLK cascade. One of the most notable substrates of KLK14 is PAR2 (Protease-Activated Receptor 2). KLK14 has been implicated in various physiological functions and is suggested to be involved in carcinogenesis, with potential as a novel biomarker for diseases such as cancer and skin disorders. It is associated with diseases like Netherton Syndrome and Ovarian Cancer. Moreover, KLK14 may play a role in the activation of membrane-type matrix metalloproteinases (MT-MMPs), which are involved in the proteolytic processing of components of the extracellular matrix, modulating the pericellular environment in physiology and pathologies.
