KLK gene family
Reviewed July 2014
What are the KLK genes?
Genes in the KLK family provide instructions for making enzymes called kallikreins, which act as serine proteases. A protease is an enzyme that breaks down proteins. The protein to be broken down attaches (binds) to the serine protease at a region of the enzyme known as the active site. In serine proteases, this active site always contains the protein building block (amino acid) serine.
The serine proteases produced from genes in the kallikrein family help break down proteins called kininogens to produce smaller proteins known as kinins. Kinins are involved in many processes in the body, including inflammation, blood clotting, and blood pressure control. Changes in genes in this family can affect the risk of developing cardiovascular disease, cancer, and other conditions influenced by these processes.
