Pdgfrb Gene Summary [Rat]
Enables phosphatidylinositol 3-kinase binding activity and platelet-derived growth factor receptor activity. Involved in several processes, including metanephros development; positive regulation of Rho protein signal transduction; and regulation of apoptotic process. Located in several cellular components, including apical plasma membrane; cell surface; and nucleus. Used to study extrahepatic cholestasis; middle cerebral artery infarction; and prostate cancer. Biomarker of hypertension; metabolic dysfunction-associated steatohepatitis; oligohydramnios; and sciatic neuropathy. Human ortholog(s) of this gene implicated in basal ganglia calcification; glioblastoma; infantile myofibromatosis; myeloproliferative neoplasm; and renal cell carcinoma. Orthologous to human PDGFRB (platelet derived growth factor receptor beta). [provided by Alliance of Genome Resources, Jul 2025]
