basic FUNCTION	potent mitogen for cells of mesenchymal origin, also involved in transformation process
	regulating the development of the craniofacial structures
	induces neovascularization by priming vascular smooth muscle cells /pericytes to release pro-angiogenic mediators (Greenberg 2008)
	regulates salivary gland morphogenesis via fibroblast growth factor expression (Yamamoto 2008)
	mesodermal PDGF signaling is not essential in heart development, although its role may be redundant with other signaling pathways (Kang 2008)
	might be involved in the activation of primordial follicles
	regulates the interaction of MTSS1L with either wild type or constitutively activated MYC-RAC1 proteins
	PDGFA signalling might regulate EZH2 expression and age-dependent pancreatic beta-cell proliferation in islets
	thought to function as a key player in the development and progression of tumor growth by regulating aspects of cell proliferation, angiogenesis and metastasis
	regulates chondrocyte proliferation through activation of ERK1/2 pathway by upregulation of GIT1 expression and RAC1 phosphorylation
	PDGFA and TGFB1 regulate acute respiratory distress syndrome (ARDS)-associated lung fibrosis through distinct signaling pathway-mediated activation of fibrosis-related proteins

a component

homodimerizing or heterodimerizing with PDGFB

INTERACTION

DNA

RNA

small molecule

protein	PDGFRA, PDGFRB
	CSPG4
	interacting with KDR and VEGFA
	PLCG1 is involved with PDGFA in phosphorylation of PEA15
	by mediating intensive F-actin accumulation at the sites of cell infiltration, WASF2, WASL, and ENAH are crucial for PI3K-dependent cell invasion induced by PDGFA
	association of MUC1 with PDGFA and MUC1 regulates the expression and secretion of PDGFA
	activates the proximal 980-bp region of the IL13 promoter
	RDX, EZR, MSN exert a redundant control on PDGFA-induced vascular smooth muscle cells (VSMC) migration by regulating focal adhesion turn-over and cell adhesion to substrate
	SOX11 promotes tumor angiogenesis through transcriptional regulation of PDGFA in mantle cell lymphoma
	SRF regulates craniofacial development through selective recruitment of MKL1 cofactors by PDGFA signaling
	PDGFA-induced migration of mesenchymal cells requires NOX4 and DUOX1/2 enzymes, which mediate redox-sensitive activation of PI3-kinase pathway and PKB/AKT1
	PI3CA/AKT2 is a direct PDGFA target that is activated in f adipocyte stem cells (ASCs) during white adipose tissue (WAT) hyperplasia and is functionally required for dermal ASC proliferation
	PDGFA/PDGFRA signalling as a tissue-autonomous regulator of contact inhibition of locomotion (CIL) by controlling N-cadherin upregulation during epithelial-to-mesenchymal transition (EMT)
