FGFR

FGFR (Fibroblast growth factor receptors) are the receptors that bind to members of the fibroblast growth factor family of proteins. Some of these receptors are involved in pathological conditions. A point mutation in FGFR3 can lead to achondroplasia. Five distinct membrane FGFR have been identified in vertebrates and all of them belong to the tyrosine kinase superfamily (FGFR1, FGFR2, FGFR3, FGFR4, FGFR6). The fibroblast growth factor family constitutes one of the most important groups of paracrine factors that act during development. They are responsible for determining certain cells to become mesoderm, for the production of blood vessels, for limb outgrowth, and for the growth and differentiation of numerous cell types.
