Growth Factor Receptor (GFR)

Growth factor receptors are a class of transmembrane proteins that bind to specific growth factors, initiating signaling cascades crucial for cell differentiation, proliferation, development, and survival. These receptors typically have an extracellular ligand-binding domain, a transmembrane domain, and a cytoplasmic kinase domain. Activation often involves ligand-induced dimerization and autophosphorylation, triggering downstream pathways like JAK/STAT, MAPK/ERK, and PI3K/Akt. Dysregulation of growth factor receptors is closely linked with oncogenesis and targeted by modern cancer therapeutics.
