Biochem/physiol Actions

Mutations in LOK (lymphocyte-oriented kinase) are linked with the anti-apoptotic effects leading to carcinogenesis. It functions as an ERM (ezrin-radixin-moesin) kinase and thereby regulates cytoskeletal organization and lymphocyte migration. It can phosphorylate PLK1 (polo-like kinase 1).

General description

LOK (lymphocyte-oriented kinase) belongs to the Ste20 (sterile 20) family of serine/threonine kinases. It is expressed in lymphocytes, brain, colon, thymus, kidney, liver, small intestine and lung. LOK is commonly referred to as STK10 (serine/threonine protein kinase 10).
