PDGFRA

Overview
PDGFRA a receptor tyrosine kinase of the PDGFR family that binds members of the platelet-derived growth factor family. The identity of the growth factor bound determines whether the functional receptor is a homodimer or a heterodimer, composed of both PDGFR-alpha and -beta. Ligand binding induces receptor dimerization and autophosphorylation. Particularly important for kidney development since mice heterozygous for the receptor exhibit defective kidney phenotypes. Chromosomal rearrangments activate PDGFRalpha by fusion to BCR, causing atypical chronic myelogenous leukemia (CML), and to FIP1L1, causing idiopathic hypereosinophilic syndrome. Activating point mutations cause a minority of gastrointestinal stromal tumors (GIST). Promoter polymorphisms linked to neural tube defects including spina bifida, verified by mouse mutant model. Inhibitors: Gleevec, Sutent. OMIM: Two alternatively-spliced isoforms have been described. Note: This description may include information from UniProtKB.
