Pdgfa Gene Summary [Rat]
Predicted to enable several functions, including platelet-derived growth factor binding activity; protein dimerization activity; and signaling receptor binding activity. Involved in several processes, including cellular response to transforming growth factor beta stimulus; response to estradiol; and response to retinoic acid. Predicted to be located in cell surface and microvillus. Predicted to be part of platelet-derived growth factor complex and platelet-derived growth factor receptor-ligand complex. Predicted to be active in extracellular space. Biomarker of chronic ulcer of skin; oligohydramnios; pancreatitis; pulmonary hypertension; and renovascular hypertension. Human ortholog(s) of this gene implicated in high grade glioma. Orthologous to human PDGFA (platelet derived growth factor subunit A). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Pdgfa often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
