Description

Platelet-derived growth factor (PDGF) is a growth factor that plays a significant role in cell proliferation and embryonic develpment. It is regulated through the platelet-derived growth factor receptor (PDGFR), a tyrosine kinase (RTK) [PMID: 1653029]. There are two types of PDGFR: alpha and beta. This entry represents the beta type PDGFR (PGFRB).

In human, there are four genes expressing PDGF chains: PDGF-A, B, C and D. They can form isoforms with each other, such as PDGF-AA, AB, BB, CC and DD [PMID: 11331881, PMID: 1709159]. PDGF isoforms bind two distinct receptors, PDGF-alpha and -beta, and this mechanism induces receptor autophosphorylation and activates signal transduction [PMID: 17656670]. PDGFR beta acts as a receptor for homodimeric PDGF-BB and PDGF-DD and for heterodimers formed by PDGF-AB [PMID: 11331882].The activities of the PDGFs have been extensively studied at the molecular and cellular level and in in vivo model systems [PMID: 9285559, PMID: 21938754, PMID: 2550144, PMID: 2554309, PMID: 1653029, PMID: 1709159, PMID: 1846866, PMID: 1314164, PMID: 1396585, PMID: 1313434]. The chromosomal aberrations involving PGFRB have been linked to several human cancers. PDGF beta is a potential target in tumor treatment [PMID: 17419949].
