Protein function

Tyrosine kinase of the non-receptor type, involved in the IFN-alpha/beta/gamma signal pathway (PubMed:7615558). Kinase partner for the interleukin (IL)-2 receptor (PubMed:11909529). .

Protein 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. .

Protein sequence and domain

Belongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily. ; Contains 1 FERM domain. ; Contains 2 protein kinase domains. ; Contains 1 SH2 domain. Possesses two phosphotransferase domains. The second one probably contains the catalytic domain, while the presence of slight differences suggest a different role for domain 1. ; The FERM domain mediates interaction with JAKMIP1.

Protein post-translational modifications

Autophosphorylated (PubMed:7615558). Phosphorylated on tyrosine residues in response to interferon gamma signaling (PubMed:7615558). Dephosphorylation of Tyr-1034 and Tyr-1035 by PTPN2 negatively regulates cytokine-mediated signaling (PubMed:11909529). .

Protein cellular localization

Endomembrane system; Peripheral membrane protein. Note=Wholly intracellular, possibly membrane associated.
