KLK

KLK is an acronym that can refer to several unrelated topics. It is not a single entity, but a shorthand used in different contexts.

In biochemistry, KLK stands for the kallikrein-related peptidase family. This group comprises 15 secreted serine proteases, KLK1 to KLK15, encoded by the KLK gene cluster on chromosome 19q13.41. These enzymes participate in regulated proteolysis in various tissues and physiological processes, including skin desquamation and semen liquefaction. Some members are involved in pathological conditions such as cancer progression and inflammatory diseases. KLK3, also known as prostate-specific antigen (PSA), is the best known member.

In finance and corporate branding, KLK is the ticker symbol for Kuala Lumpur Kepong Berhad, a Malaysian plantation and agro-based foods company. KLK operates plantations producing palm oil and rubber and has processing operations such as mills and refineries. It is listed on Bursa Malaysia and has activities in Malaysia, Indonesia, and other regions.

Other uses of the acronym KLK exist in various organizations or products, but they are less common. When encountering KLK, the intended meaning is usually evident from the context.
