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]. FGFs are mitogens, which stimulate growth or differentiation of cells of mesodermal or neuroectodermal origin. 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. FGFs have internal pseudo-threefold symmetry (beta-trefoil topology) [PMID: 10830168]. 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. Upon binding to FGF, the receptors dimerize and their intracellular tyrosine kinase domains become active [PMID: 7583099].

This entry represents fibroblast growth factor 14 (FGF14), also known as fibroblast growth factor homologous factor 4. In mouse, FGF14 is widely expressed in the brain, spinal cord, major arteries and thymus [PMID: 10640713]. The protein is involved in neuronal development and function. FGF14-deficient mice suffer from severe ataxia and other neurological deficits [PMID: 17678857]. Defects in the human FGF14 gene cause Spinocerebellar ataxia, characterised by ataxia with tremor, orofacial dyskinesia, psychiatric symptoms and cognitive deficits [PMID: 12489043].
