標靶描述

Fibroblast growth factor receptor 4 (UniProt: P22455; also known as EC: 2.7.10.1, FGFR-4, CD334) is encoded by the FGRF4 (also known as JTK2, TKF) gene (Gene ID: 2264) in human. FGFR-4 is a highly conserved, single-pass type I membrane protein with tyrosine kinase activity that serves as a cell surface receptor for fibroblast growth factors and regulates cell proliferation differentiation, and migration. FGFR-4 is expressed in gastrointestinal epithelial cells, pancreas, and gastric and pancreatic cancer cell lines. In the absence of a ligand, it is present as a monomer in an inactive conformation. Upon ligand binding it homodimerizes into an active conformation with autophosphorylation of tyrosine residues. FGFR-4 is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off in the mature form. It contains an extracellular domain (aa 22-369), a transmembrane domain (aa 370-390), and a cytoplasmic domain (aa 391-802). FGFR-4 undergoes N-glycosylation, and when not fully glycosylated, it can undergo proteasomal degradation. FGFR-4 signaling is down-regulated by receptor internalization and degradation. MMP14 is reported to promote internalization and degradation of FGFR-4. Mutations that lead to constitutive kinase activation or impair normal FGFR-4 inactivation lead to aberrant signaling leading to tumor growth. Over-expression of FGFR4 is reported in almost all human prostate cancers and its R388G mutation is associated with tumor progression. It leads to increased receptor stability and sustained receptor activation. (Ref.: Turkington, RC et al. (2014). Cell Death Dis. 5; e1046; Wang, J., et al. (2008). Neoplasia. 10(8); 847-856).
