Fibroblast Growth Factor Receptor 3 (FGFR3)

Target
FGFR3
Molecular classification
Receptor, Tyrosine Kinase, Fibroblast Growth Factor Receptor Family
01

Overview

Fibroblast Growth Factor Receptor 3 (FGFR3) is a transmembrane receptor tyrosine kinase that plays a crucial role in regulating cell growth, differentiation, and development. It is involved in various processes including bone growth, angiogenesis, and tumorigenesis. Mutations in FGFR3 are associated with skeletal dysplasias like achondroplasia and cancers such as bladder urothelial carcinoma. Targeting FGFR3 is of therapeutic interest, with drugs like erdafitinib showing efficacy against specific mutations.
