Application Abreviews Notes
Dot blot 1/1000.
WB 1/1000. Detects a band of approximately 133 kDa (predicted molecular weight: 133 kDa).


  • Function
    Tyrosine kinase of the non-receptor type, involved in the IFN-alpha/beta/gamma signal pathway. Kinase partner for the interleukin (IL)-2 receptor.
  • Tissue specificity
    Expressed at higher levels in primary colon tumors than in normal colon tissue. The expression level in metastatic colon tumors is comparable to the expression level in normal colon tissue.
  • Sequence similarities
    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.
  • Domain
    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.
    The FERM domain mediates interaction with JAKMIP1.
  • Cellular localization
    Endomembrane system. Wholly intracellular, possibly membrane associated.
