|FUNCTION: Plays a role as adhesion receptor functioning by homophilic interactions and by clustering. Recruits SH2 domain- containing proteins SH2D1A/SAP. Increases proliferative responses of activated T-cells and SH2D1A/SAP does not seen be required for this process. Homophilic interactions enhance interferon gamma/IFNG secretion in lymphocytes and induce platelet stimulation via a SH2D1A/SAP-dependent pathway. May serve as a marker for hematopoietic progenitor cells. SUBUNIT: Homodimer; via its extracellular domain. Forms a head to tail dimer with a CD48 molecule from another cell. Interacts with SH2 domain-containing proteins SH2D1A/SAP and SH2D1B/hEAT-2. Interacts with tyrosine-protein phosphatases PTPN6 and PTPN11 via its phosphorylated cytoplasmic domain, and this interaction is blocked by SH2D1A. TISSUE SPECIFICITY: Predominantly expressed in hematopoietic tissues, such as lymph node, spleen and peripheral leukocytes. Expressed in macrophages, B-cells, monocytes, platelets, thymocytes, T-cells and dendritic cells. Highly expressed in memory T-cells. DEVELOPMENTAL STAGE: Expression is slightly increased in naive B- cells after the first dividion. By contrast, expression on memory B-cells decreased with each successive division. DOMAIN: ITSM (immunoreceptor tyrosine-based switch motif) motif is a cytoplasmic motif which may bind SH2D1A.|
