Family relationships

Description

Fibroblast growth factors (FGFs) [PMID: 2549857, PMID: 3072709] are a family of multifunctional proteins, often referred to as 'promiscuous growth factors' due to their diverse actions on multiple cell types [PMID: 1705486, PMID: 8760337]. The function of FGFs in developmental processes include mesoderm induction, anterior-posterior patterning, limb development, and neural induction and development. In mature tissues, they are involved in diverse processes including keratinocyte organisation and wound healing [PMID: 11276432, PMID: 23000357, PMID: 15689573, PMID: 10441498, PMID: 23108135, PMID: 23016864]. FGF involvement is critical during normal development of both vertebrates and invertebrates, and irregularities in their function leads to a range of developmental defects [PMID: 1649700, PMID: 11746231, PMID: 14745970, PMID: 8978613]. Fibroblast growth factors are heparin-binding proteins and interactions with cell-surface-associated heparan sulfate proteoglycans have been shown to be essential for FGF signal transduction. There are currently over 20 different FGF family members that have been identified in mammals, all of which are structurally related signaling molecules [PMID: 8652550, PMID: 11276432]. They exert their effects through four distinct membrane fibroblast growth factor receptors (FGFRs), FGFR1 to FGFR4 [PMID: 7583099], which belong to the tyrosine kinase superfamily.

This entry represents fibroblast growth factor 4 (FGF4), also known as heparin secretory transforming protein 1. This protein plays an important role in the regulation of embryonic development, cell proliferation and differentiation [PMID: 8663044]. Studies on the mouse protein suggest a function in bone morphogenesis and limb development through the sonic hedgehog (SHH) signaling pathway [PMID: 9477322, PMID: 8001146].
