Also known as SKAP55
Summary
SKAP1 (src kinase associated phosphoprotein 1, HGNC:15605) is a protein-coding gene on chromosome 17q21.32, encoding Src kinase-associated phosphoprotein 1 (Q86WV1). Positively regulates T-cell receptor signaling by enhancing the MAP kinase pathway.
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. 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.
Subunit / interactions. Homodimer. Interacts with FYN. Interacts with PTPRC. Interacts with GRB2 when phosphorylated on Tyr-271. Interacts with FYB1, which is required for SKAP2 protein stability. Part of a complex consisting of SKAP1, FYB1 and CLNK. Interacts with RASGRP1. Interacts with FYB2.
Subcellular location. Cytoplasm. Nucleus. Cell membrane.
Tissue specificity. Highly expressed in thymocytes and peripheral blood lymphocytes. Also expressed in spleen cells and testis. Present in T-cells (at protein level).
Post-translational modifications. Phosphorylated on tyrosines. Phosphorylation by FYN on Tyr-271 is required for GRB2 interaction. Phosphorylation by FYN on Tyr-295 abolishes interaction with FYB1. Tyr-232 is dephosphorylated by PTPRC.
Domain organisation. The SH3 domain interacts with FYB1.
Similarity. Belongs to the SKAP family.
