Background： This gene encodes a T cell adaptor protein, a class of intracellular molecules with modular domains capable of recruiting additional proteins but that exhibit no intrinsic enzymatic activity. The encoded protein contains a unique N-terminal region followed by a PH domain and C-terminal SH3 domain. Along with the adhesion and degranulation-promoting adaptor protein, the encoded protein plays a critical role in inside-out signaling by coupling T-cell antigen receptor stimulation to the activation of integrins.

Function：domain:The SH3 domain interacts with FYB.,function:Positively regulates T-cell receptor signaling by enhancing the MAP kinase pathway. Required for optimal conjugation between T-cells and antigen-presenting cells by promoting the clustering of integrin ITGAL on the surface of T-cells. May be involved in high affinity immunoglobulin epsilon receptor signaling in mast cells.,PTM:Phosphorylated on tyrosines. Phosphorylation by FYN on Tyr-271 is required for GRB2 interaction. Phosphorylation by FYN on Tyr-295 abolishes interaction with FYB. Tyr-232 is dephosphorylated by PTPRC.,similarity:Belongs to the SKAP family.,similarity:Contains 1 PH domain.,similarity:Contains 1 SH3 domain.,subcellular location:Upon T-cell stimulation, translocates to lipid rafts at the cell membrane.,subunit:Homodimer. Interacts with FYN and PTPRC. Interacts with GRB2 when phosphorylated on Tyr-271. Interacts with F

Subcellular Location：Cytoplasm . Nucleus . Cell membrane . Upon T-cell stimulation, translocates to lipid rafts at the cell membrane. .

Expression：Highly expressed in thymocytes and peripheral blood lymphocytes. Also expressed in spleen cells and testis. Present in T-cells (at protein level).
