MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an intracellular tyrosine kinase expressed in T-cells. The protein contains both SH2 and SH3 domains which are often found in intracellular kinases. It is thought to play a role in T-cell proliferation and differentiation. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for disruptions in this gene display decreased percentages of CD4 and CD8 cells, increased percentage of B cells, impaired T cell receptor signaling, and increased susceptibility to Toxoplasma gondii infection. [provided by MGI curators]
