Commun. 3:876-876(2012). CC -!- FUNCTION: Plasma glycoprotein that binds a number of ligands such as CC heme, heparin, heparan sulfate, thrombospondin, plasminogen, and CC divalent metal ions. Inhibits rosette formation. Acts as an adapter CC protein and implicated in regulating many processes such as immune CC complex and pathogen clearance, cell adhesion, angiogenesis, CC coagulation and fibrinolysis. Mediates clearance of necrotic cells CC through enhancing the phagocytosis of necrotic cells in a heparan CC sulfate-dependent pathway. This process can be regulated by the CC presence of certain HRG ligands such as heparin and zinc ions. Binds to CC IgG subclasses of immunoglobins containing kappa and lambda light CC chains with different affinities regulating their clearance and CC inhibiting the formation of insoluble immune complexes. Tethers CC plasminogen to the cell surface. Binds T-cells and alters the cell CC morphology. Modulates angiogenesis by blocking the CD6-mediated CC antiangiongenic effect of thrombospondins, THBS1 and THBS2 (By CC similarity). {ECO:0000250}. CC -!- SUBUNIT: Interacts with THBS1 (via the TSP type I repeats); the CC interaction blocks the antiangiogenic effect of THBS1 with CD36. CC Interacts with HPSE; the interaction is enhanced at acidic pH, CC partially inhibits binding of HPSE to cell surface receptors and CC modulates its enzymatic activity. Interacts (via the HRR domain) with CC TMP1; the interaction partially mediates the antiangiogenic properties CC of HRG. Interacts with kappa and lambda light chains of IgG molecules. CC Interacts with ATP5F1A; the interaction occurs on the surface of T- CC cells and alters their cell morphology in concert with CONA. Binds IgG CC molecules containing kappa and lambda light chains and inhibits the CC formation of insoluble immunoglobulin complexes. Interacts with F12; CC the interaction, which is enhanced in the presence of zinc ions and CC inhibited by heparin-binding to HRG, inhibits factor XII autoactivation CC and contact-initiated coagulation (By similarity). Interacts with PLG CC (via its Kringle domains); the interaction tethers PLG to the cell CC surface and enhances its activation. Interacts (via the HRR domain) CC with TPM1; the interaction appears to contribute to the antiangiogenic CC properties of the HRR domain. Interacts with THBS2; the interaction CC blocks the antiangiogenic effect of THBS2 with CD36 (By similarity). CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:10849117}. CC -!- TISSUE SPECIFICITY: Expressed in liver, blood plasma, serum and in CC platelets. Also present in fibrin clots, wound fluid from acute wounds CC and chronic leg ulcers. {ECO:0000269|PubMed:10849117}. CC -!- DOMAIN: The His-rich (HRR) region contains approximately 12 tandem CC internal repeats of the 5-residue G[H/P][H/P]PH consensus sequence. HRR CC binds heparan sulfate and possesses antiangiogenic, antibacterial and CC antifungal properties through binding Candida cells, and preferentially CC lysing the ergosterol-containing liposomes at low pH. The tandem CC repeats also bind divalent metal ions and heme (By similarity). CC {ECO:0000250}. CC -!- DOMAIN: The cystatin domains can also bind heparan sulfate. Binding is CC enhanced in the presence of zinc ions (By similarity). {ECO:0000250}. CC -!- PTM: N-glycosylated. {ECO:0000250}. CC -!- PTM: Proteolytic cleavage produces several HRG fragments which are CC mostly disulfide-linked and, therefore, not released. Cleavage by CC plasmin is inhibited in the presence of heparin, zinc ions or in an CC acidic environment. Cleavage reduces binding of HRG to heparan sulfate, CC but enhances the ability of HRG to bind and tether plasminogen to the CC cell surface. On platelet activation, releases a 33 kDa antiangiogenic CC peptide which encompasses the HRR. Also cleaved in the C-terminal by CC plasmin (By similarity). {ECO:0000250}.
