target relevance
CD47 (Cluster of Differentiation 47) also known as integrin associated protein (IAP) is a transmembrane protein that in humans is encoded by the CD47 gene. CD47 belongs to the immunoglobulin superfamily and partners with membrane integrins and also binds the ligands thrombospondin-1 (TSP-1) and signal-regulatory protein alpha (SIRPα).CD-47 acts as a don't eat me signal to macrophages of the immune system which has made it a potential therapeutic target in some cancers.
Protein names
Leukocyte surface antigen CD47 (Antigenic surface determinant protein OA3) (Integrin-associated protein) (IAP) (Protein MER6) (CD antigen CD47)
Gene names
CD47,CD47 MER6
FUNCTION: Adhesive protein that mediates cell-to-cell interactions (PubMed:11509594, PubMed:15383453). Acts as a receptor for thrombospondin THBS1 and as modulator of integrin signaling through the activation of heterotrimeric G proteins (PubMed:19004835, PubMed:7691831, PubMed:8550562). Involved in signal transduction, cardiovascular homeostasis, inflammation, apoptosis, angiogenesis, cellular self-renewal, and immunoregulation (PubMed:11509594, PubMed:15383453, PubMed:19004835, PubMed:27742621, PubMed:32679764, PubMed:7691831, PubMed:8550562). Plays a role in modulating pulmonary endothelin EDN1 signaling (PubMed:27742621). Modulates nitrous oxide (NO) signaling, in response to THBS1, hence playing a role as a pressor agent, supporting blood pressure (By similarity). Plays an important role in memory formation and synaptic plasticity in the hippocampus (By similarity). Receptor for SIRPA, binding to which prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells (PubMed:11509594). Interaction with SIRPG mediates cell-cell adhesion, enhances superantigen-dependent T-cell-mediated proliferation and costimulates T-cell activation (PubMed:15383453). Positively modulates FAS-dependent apoptosis in T-cells, perhaps by enhancing FAS clustering (By similarity). Plays a role in suppressing angiogenesis and may be involved in metabolic dysregulation during normal aging (PubMed:32679764). In response to THBS1, negatively modulates wound healing (By similarity). Inhibits stem cell self-renewal, in response to THBS1, probably by regulation of the stem cell transcription factors POU5F1/OCT4, SOX2, MYC/c-Myc and KLF4 (By similarity). May play a role in membrane transport and/or integrin dependent signal transduction (PubMed:7691831). May prevent premature elimination of red blood cells (By similarity). {ECO:0000250|UniProtKB:P97829, ECO:0000250|UniProtKB:Q61735, ECO:0000269|PubMed:11509594, ECO:0000269|PubMed:15383453, ECO:0000269|PubMed:19004835, ECO:0000269|PubMed:27742621, ECO:0000269|PubMed:32679764, ECO:0000269|PubMed:7691831, ECO:0000269|PubMed:8550562}.
Subellular location
SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:7691831}; Multi-pass membrane protein {ECO:0000269|PubMed:7691831}.
TISSUE SPECIFICITY: Very broadly distributed on normal adult tissues, as well as ovarian tumors, being especially abundant in some epithelia and the brain.
SUBUNIT: Monomer (PubMed:18657508). Interacts with THBS1 (via the C-terminal domain) (PubMed:19004835, PubMed:8550562). Interacts with SIRPA (PubMed:11509594). Interacts with FAS/CD95; interaction may be enhanced by functional activation (PubMed:15917238). Interacts with SIRPG, UBQLN1 and UBQLN2 (PubMed:10549293, PubMed:15383453, PubMed:18657508). May interact with fibrinogen (PubMed:22079249). {ECO:0000269|PubMed:10549293, ECO:0000269|PubMed:11509594, ECO:0000269|PubMed:15383453, ECO:0000269|PubMed:15917238, ECO:0000269|PubMed:18657508, ECO:0000269|PubMed:19004835, ECO:0000269|PubMed:22079249, ECO:0000269|PubMed:8550562}.
