SKAP1 Polyclonal Antibody

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 FYB, which is required for SKAP2 protein stability. Part of a complex consisting of SKAP1, FYB and CLNK. Interacts with RASGRP1.,tissue specificity:Highly expressed in thymocytes and peripheral blood lymphocytes. Also expressed in spleen cells and testis. Present in T-cells (at protein level).,
