Background
FGF acidic; also known as ECGF; FGF-1and HBGF-1; is a non-glycosylated heparin binding growth factor that is expressed in the brain; kidney; retina; smooth muscle cells; bone matrix; osteoblasts; astrocytes and endothelial cells. It is a mitogenic peptide that is produced by multiple cell types and stimulates the proliferation of cells of mesodermal; ectodermal; and endodermal origin. Its association with heparan sulfate is a prerequisite for activation of FGF receptors. Internalized FGF acidic migrates to the nucleus where it is phosphorylated by nuclear PKC delta; exported to the cytosol; dephosphorylated; and degraded. Intracellular FGF acidic inhibits p53 activity and proapoptotic signaling.
