  • 功能Tyrosine kinase of the non-receptor type, involved in the interleukin-2 and interleukin-4 signaling pathway. Phosphorylates STAT6, IRS1, IRS2 and PI3K.
  • 组织特异性In NK cells and an NK-like cell line but not in resting T-cells or in other tissues. The S-form is more commonly seen in hematopoietic lines, whereas the B-form is detected in cells both of hematopoietic and epithelial origins.
  • 疾病相关Defects in JAK3 are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-negative (T(-)B(+)NK(-) SCID) [MIM:600802]. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development.
  • 序列相似性Belongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily.
    Contains 1 FERM domain.
    Contains 1 protein kinase domain.
    Contains 1 SH2 domain.
  • 结构域Possesses two phosphotransferase domains. The second one probably contains the catalytic domain (By similarity), while the presence of slight differences suggest a different role for domain 1.
  • 翻译后修饰Tyrosine phosphorylated in response to IL-2 and IL-4.
  • 细胞定位Endomembrane system. Wholly intracellular, possibly membrane associated.
  • Information by UniProt
