cd05861: Ig_PDGFR-alphabeta (this model, PSSM-Id:143269 is obsolete and has been replaced by 409447)
Immunoglobulin (Ig)-like domain of platelet-derived growth factor (PDGF) receptors (R), alpha (CD140a), and beta (CD140b)
Ig_PDGFR-alphabeta: immunoglobulin (Ig)-like domain of platelet-derived growth factor (PDGF) receptors (R), alpha (CD140a), and beta (CD140b). PDGF is a potent mitogen for connective tissue cells. PDGF-stimulated processes are mediated by three different PDGFs (PDGF-A,-B, and C). PDGFRalpha binds to all three PDGFs, whereas the PDGFRbeta binds only to PDGF-B. PDGFRs alpha and beta have similar organization: an extracellular component with five Ig-like domains, a transmembrane segment, and a cytoplasmic portion having protein tyrosine kinase activity. In mice, PDGFRalpha and PDGFRbeta are essential for normal development.
