质量标准:【产品介绍】JAK3 is a member of the Janus family
(JAK) tyrosine kinases involved in cytokine
receptor-mediated intracellular signal transduction. The
JAK family is constitutively associated with
cytokine receptors; upon binding to the receptor,
the cytokine becomes phosphorylated (1). JAK
also phosphorylates the cytokine receptor on tyrosine
(Tyr) residues that serve as docking sites for
cytoplasmic signal transducers and activators
of transcription (STAT) proteins (2). Activated
STATs translocate to the nucleus to mediate
gene transcription (1). JAK3 is unique among JAK
family members because it serves a function in
normal lymphocyte development. In addition, JAK3 is the
only one that interacts with the common gamma chain of
the following Interleukin receptors: IL-2, IL-4, IL-7,
IL-9, and IL-15 receptors (3). Loss of JAK3 function
causes a severe block in T-cell and natural killer (NK)
cell development (4). Defects in JAK3 are a cause of
severe combined immunodeficiency (SCID), characterized by
an absence of T-cell-mediated cellular immunity (5).
