Supplementary information

Tissue kallikrein also known as KLK1 is a serine protease enzyme that plays an important role in the cleavage of kininogen to produce kinins. This enzyme with a molecular weight of approximately 30 kDa exists in various tissues like the kidney pancreas and salivary glands. The protein is part of the kallikrein family and is expressed prominently in these areas. You can commonly measure its levels through ELISA assays labeled "kallikrein ELISA" or specific assays like the "kallikrein 3 ELISA."

Biological function summary

Tissue kallikrein contributes to vasodilation and blood pressure regulation by producing bradykinin a peptide with strong vasodilator properties. It does not function alone but may interact with other enzymes to amplify its effect. Tissue kallikrein belongs to a larger family of kallikrein-related peptidases which perform various physiological roles adding complexity to its functional network within the human body.

Pathways

This enzyme participates extensively in the kallikrein-kinin system. A significant interaction happens within the renin-angiotensin-aldosterone system contributing to blood pressure regulation fluid balance and cardiovascular function. It engages with related proteins such as kininogen and bradykinin establishing important checkpoints within these pathways.

Abnormalities in tissue kallikrein regulation link to hypertension and inflammatory diseases like rheumatoid arthritis. Dysregulation may alter interactions with proteins like kininogen leading to altered inflammatory responses or blood pressure issues. Understanding these relationships can inform therapeutic strategies targeting the kallikrein-kinin system for improved disease management.
