Protein

Platelet-derived growth factor subunit A

Gene

Pdgfa

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Growth factor that plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. Potent mitogen for cells of mesenchymal origin. Required for normal lung alveolar septum formation during embryogenesis, normal development of the gastrointestinal tract, normal development of Leydig cells and spermatogenesis. Required for normal oligodendrocyte development and normal myelination in the spinal cord and cerebellum. Plays an important role in wound healing. Signaling is modulated by the formation of heterodimers with PDGFB.7 Publications
