Gene: ITGB3 (integrin subunit beta 3) Homo sapiens
Symbol: ITGB3
Name: integrin subunit beta 3
CRRD ID: 1345363
Description: Exhibits several functions, including fibronectin binding activity; protein disulfide isomerase activity; and signaling receptor binding activity. Contributes to C-X3-C chemokine binding activity and growth factor binding activity. Involved in several processes, including negative regulation of lipid localization; negative regulation of macrophage derived foam cell differentiation; and regulation of protein metabolic process. Localizes to several cellular components, including alphav-beta3 integrin-HMGB1 complex; alphav-beta3 integrin-IGF-1-IGF1R complex; and cell projection membrane. Implicated in several diseases, including acute myeloid leukemia; autoimmune thrombocytopenic purpura; blood platelet disease (multiple); end stage renal disease; and non-arteritic anterior ischemic optic neuropathy. Biomarker of several diseases, including Graves' disease; carcinoma (multiple); diabetic retinopathy; myelodysplastic syndrome; and platelet-type bleeding disorder 16.
Type: protein-coding
