Gene Symbol CD84
Gene Full Name CD84 molecule
Background CD84 is a highly glycosylated homophilic receptor of SLAM family. It is expressed on platelets and various types of leukocytes, especially following their activation. Ligation of CD84 leads to its phosphorylation on tyrosine residues within the cytoplasmic tail. These docking sites are recognized by downstream signaling molecules, such as phosphatase SHP-2 and adaptor protein SAP/SH2D1A. The function of CD84 has not been fully elucidated yet. Although predominantly activating receptor, its modulating activity was also demonstrated.
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. [UniProt]
Research Area Developmental Biology antibody; Immune System antibody
Calculated MW 39 kDa
PTM Phosphorylated by tyrosine-protein kinase LCK on tyrosine residues following ligation induced by agonist monoclonal antibody. The association with SH2D1A is dependent of tyrosine phosphorylation of its cytoplasmic domain. Phosphorylated on Tyr-296 and Tyr-316 following platelet aggregation. Phosphorylated on tyrosine residues upon high affinity immunoglobulin epsilon receptor aggregation in mast cells.
