PDGFRA (T674I Mutant) Proteins

Protein Information

PDGFRA is a cell surface receptor tyrosine kinase which binds members of the platelet-derived growth factor family. PDGFRA T674I is a Gleevec resistant form of PDGFRA. These growth factors are mitogens for cells of mesenchymal origin. The identity of the growth factor bound to a receptor monomer determines whether the functional receptor is a homodimer or a heterodimer, composed of both platelet-derived growth factor receptor alpha and beta polypeptides. Studies in knockout mice, where homozygosity is lethal, indicate that the alpha form of the platelet-derived growth factor receptor is particularly important for kidney development since mice heterozygous for the receptor exhibit defective kidney phenotypes.
