Protein Structure
UniProt Annotation
Function Negatively regulates TCR (T-cell antigen receptor)- mediated signaling in T-cells and FCER1 (high affinity immunoglobulin epsilon receptor)-mediated signaling in mast cells. Promotes CSK activation and recruitment to lipid rafts, which results in LCK inhibition. Inhibits immunological synapse formation by preventing dynamic arrangement of lipid raft proteins. May be involved in cell adhesion signaling. {ECO:0000269PubMed:10790433}.
Subcellular Localization Cell membrane {ECO:0000269PubMed:10790433, ECO:0000269PubMed:18070987}; Single-pass type III membrane protein {ECO:0000269PubMed:10790433, ECO:0000269PubMed:18070987}. Note=Present in lipid rafts.
Disease Associations
Tissue Specificity Ubiquitously expressed. Present in germinal center B-cells, plasma cells, T-cells, monocytes and platelets (at protein level). {ECO:0000269PubMed:10790433, ECO:0000269PubMed:16160011}.
