CC -!- FUNCTION: May act as receptor for class I MHC antigens. Becomes
CC activated upon coligation with immune receptors, such as FCGR2B and the
CC B-cell receptor. Down-regulates antigen-induced B-cell activation by
CC recruiting phosphatases to its immunoreceptor tyrosine-based inhibitor
CC motifs (ITIM). {ECO:0000250|UniProtKB:P97484}.
CC -!- SUBUNIT: Interacts with LYN, PTPN6/SHP-1 and PTPN11/SHP-2.
CC {ECO:0000250|UniProtKB:P97484}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P97484};
CC Single-pass membrane protein {ECO:0000255}.
CC -!- DOMAIN: Contains 3 copies of a cytoplasmic motif that is referred to as
CC the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is
CC involved in modulation of cellular responses. The phosphorylated ITIM
CC motif can bind the SH2 domain of several SH2-containing phosphatases,
CC including PTPN6/SHP-1, resulting in the dephosphorylation of the
CC downstream protein kinases SYK and BTK. {ECO:0000250|UniProtKB:P97484}.
CC -!- PTM: Phosphorylated on tyrosine residues by LYN. Phosphorylation at
CC Tyr-697 and Tyr-727 is important for interaction with PTPN6/SHP-1 and
CC PTPN11/SHP-2. {ECO:0000250|UniProtKB:P97484}.
