Description
Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays a role in the regulation of cell proliferation, differentiation and migration, and in regulation of lipid metabolism, bile acid biosynthesis, glucose uptake, vitamin D metabolism and phosphate homeostasis. Required for normal down-regulation of the expression of CYP7A1, the rate-limiting enzyme in bile acid synthesis, in response to FGF19. Phosphorylates PLCG1 and FRS2. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Promotes SRC-dependent phosphorylation of the matrix protease MMP14 and its lysosomal degradation. FGFR4 signaling is down-regulated by receptor internalization and degradation; MMP14 promotes internalization and degradation of FGFR4. Mutations that lead to constitutive kinase activation or impair normal FGFR4 inactivation lead to aberrant signaling.

Descripción
Fibroblast growth factor receptor 4 (FGFR4) FGFR4 is a member of the fibroblast growth factor receptor (FGFR) family, characterized as a transmembrane tyrosine kinase receptor that binds FGFs to regulate cell proliferation, differentiation, migration, and survival. Structurally, FGFR4 consists of an extracellular ligand-binding domain composed of three immunoglobulin-like loops, a single transmembrane domain, and an intracellular tyrosine kinase domain. FGFR4 plays essential roles in embryonic development, metabolism, and tissue homeostasis, particularly in liver, muscle, and endocrine tissues. Ligand binding activates downstream signaling cascades, including the MAPK, PI3K-AKT, and STAT pathways, which are critical for cell growth and survival. Dysregulation of FGFR4 signaling has been implicated in various cancers, such as hepatocellular carcinoma and rhabdomyosarcoma, where overexpression or mutation drives tumor growth and metastasis. Its selective expression in specific tissues and its involvement in metabolic regulation, including bile acid synthesis, highlight its specialized biological functions and potential as a therapeutic target in oncology and metabolic disorders.
