Keratinocyte Growth Factor Receptor (FGFR2)

Target
FGFR2
Molecular classification
Receptor, Transmembrane Tyrosine Kinase
01

Overview

Keratinocyte growth factor receptor (FGFR2) is a transmembrane tyrosine kinase receptor belonging to the fibroblast growth factor receptor family. It plays a crucial role in cell proliferation, differentiation, mitogenesis, tissue repair, and embryonic development by binding to fibroblast growth factors and initiating downstream signaling cascades. Mutations and dysregulation of FGFR2 are associated with various congenital disorders and cancers.
