Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. The encoded protein is a cell surface glycoprotein that is known to complex with integrins. It may function as a blood platelet activation marker. Deficiency of this protein is associated with Hermansky-Pudlak syndrome. Also this gene has been associated with tumor progression. Alternative splicing results in multiple transcript variants encoding different protein isoforms. [provided by RefSeq, Apr 2012]. * **UniProt Summary**: Functions as cell surface receptor for TIMP1 and plays a role in the activation of cellular signaling cascades. Plays a role in the activation of ITGB1 and integrin signaling, leading to the activation of AKT, FAK/PTK2 and MAP kinases. Promotes cell survival, reorganization of the actin cytoskeleton, cell adhesion, spreading and migration, via its role in the activation of AKT and FAK/PTK2. Plays a role in VEGFA signaling via its role in regulating the internalization of KDR/VEGFR2. Plays a role in intracellular vesicular transport processes, and is required for normal trafficking of the PMEL luminal domain that is essential for the development and maturation of melanocytes. Plays a role in the adhesion of leukocytes onto endothelial cells via its role in the regulation of SELP trafficking. May play a role in mast cell degranulation in response to Ms4a2/FceRI stimulation, but not in mast cell degranulation in response to other stimuli. {ECO:0000269|PubMed:16917503, ECO:0000269|PubMed:21803846, ECO:0000269|PubMed:21962903, ECO:0000269|PubMed:23632027, ECO:0000269|PubMed:24635319}. |Tetraspannin| |multivesicular body, internal vesicle| |platelet dense granule membrane| |positive regulation of integrin-mediated signaling pathway| |pigment granule maturation| |endosome to melanosome transport| |endosome to pigment granule transport| |multivesicular body membrane| |pigment accumulation| |cellular pigment accumulation| |regulation of integrin-mediated signaling pathway| |regulation of vascular endothelial growth factor signaling pathway| |endosome lumen| |regulation of cellular response to vascular endothelial growth factor stimulus| |positive regulation of receptor internalization| |pigment cell differentiation| |intrinsic component of plasma membrane| |developmental pigmentation| |cellular pigmentation| |positive regulation of receptor-mediated endocytosis| |regulation of receptor internalization| |azurophil granule membrane| |regulation of potassium ion transmembrane transport| |pigmentation| |regulation of potassium ion transport| |regulation of receptor-mediated endocytosis| |positive regulation of endocytosis| |melanosome| |late endosome membrane| |cell-matrix adhesion| |platelet degranulation| |cell-substrate adhesion| |regulation of endocytosis| |endosome membrane| |developmental maturation| |regulation of cellular response to growth factor stimulus| |lysosomal membrane| |regulation of cation transmembrane transport| |regulation of metal ion transport| |regulation of ion transmembrane transport| |neutrophil degranulation| |neutrophil activation involved in immune response| |neutrophil mediated immunity| |neutrophil activation| |granulocyte activation| |leukocyte degranulation| |myeloid leukocyte mediated immunity| |myeloid cell activation involved in immune response| |regulation of vesicle-mediated transport| |regulation of transmembrane transport| |myeloid leukocyte activation| |cell surface| |leukocyte activation involved in immune response| |cell activation involved in immune response| |regulation of ion transport| |regulated exocytosis| |leukocyte mediated immunity| |exocytosis| |leukocyte activation| |cell adhesion| |biological adhesion| |cell migration| |positive regulation of transport| |secretion by cell| |export from cell| |cell activation| |cell motility| |localization of cell| |immune effector process| |secretion| |positive regulation of cellular component organization| |locomotion| |integral component of plasma membrane| |protein transport| |intracellular transport| |peptide transport| |movement of cell or subcellular component| |amide transport| |cellular protein localization| |extracellular space| |cellular macromolecule localization| |establishment of protein localization| |positive regulation of signal transduction| |positive regulation of cell communication| |positive regulation of signaling| |establishment of localization in cell| |nitrogen compound transport| |regulation of transport| |immune response| |vesicle-mediated transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp53|Suberoylanilide-Hydroxamic-Acid 0.02μM R01 exp53]]|-1.76| |[[:results:exp16|DABN 2μM R00 exp16]]|-1.71| No correlation found to any other genes in chemogenomics.
