Linker of activated T cells : ウィキペディア英語版 | Linker of activated T cells
The Linker for Activation of T cells, also known as LAT, is a protein which in humans is encoded by the ''LAT'' gene. Alternative splicing results in multiple transcript variants encoding different isoforms. == Function ==
The protein encoded by this gene is phosphorylated by ZAP70/Syk protein tyrosine kinases following activation of the T-cell antigen receptor (TCR) signal transduction pathway. This transmembrane protein localizes to lipid rafts (also known as glycosphingolipid-enriched microdomains or GEMs) and acts as a docking site for SH2 domain-containing proteins. Upon phosphorylation, this protein recruits multiple adaptor proteins and downstream signaling molecules into multimolecular signaling complexes located near the site of TCR engagement.〔
