Predicted to enable SH2 domain binding activity. Predicted to be involved in B cell activation; B cell receptor signaling pathway; and calcium-mediated signaling. Predicted to be located in membrane raft. Predicted to be active in plasma membrane. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Human ortholog(s) of this gene implicated in Williams-Beuren syndrome. Orthologous to human LAT2 (linker for activation of T cells family member 2).
MGI Description
PHENOTYPE: Mice homozygous for a null allele have abnormal mast cell physiology and increased anti-nuclear antigen antibody level. Mice homozygous for another null allele show abnormal mast cell physiology, hyperactivated T cells, higher cytokine production, spleenhyperplasia and increased autoantibody level.
