JAK3(redirected from Leukocyte janus kinase)
JAK3A gene on chromosome 19p13.1 that encodes a member of the Janus kinase (JAK) family of tyrosine kinases, which are involved in cytokine-receptor-mediated intracellular signal transduction. JAK3 is primarily expressed in immune cells and transduces a signal in response to activation via tyrosine phosphorylation by interleukin receptors.
JAK3 mutations are linked to autosomal severe combined immunodeficiency disease (SCID).
