FGF2

FGF2‏‎ or Fibroblast Growth Factor 2 is a type of protein and a member of the Fibroblast Growth Factor (FGF) family. It is also known as basic fibroblast growth factor (bFGF) and FGF-β. FGF2‏‎ plays a crucial role in cell proliferation, cell differentiation, and angiogenesis, which is the formation of new blood vessels from pre-existing ones.

Function

FGF2‏‎ is a potent modulator of cell growth and cell differentiation. It is involved in a variety of biological processes, including embryonic development, tissue repair, tumor growth, and invasion. FGF2‏‎ achieves its functions by binding to its receptors, known as FGF receptors (FGFRs), which triggers a cascade of downstream signal transduction pathways.

Structure

FGF2‏‎ is a single-chain polypeptide composed of 146 amino acids. It lacks a signal peptide, which is unusual for a secreted protein. Instead, FGF2‏‎ is exported from cells by a non-classical pathway, which is not yet fully understood.

Clinical Significance

Due to its role in cell growth and differentiation, FGF2‏‎ has been implicated in a variety of diseases, including cancer, diabetes, and atherosclerosis. It is also being investigated for its potential use in tissue engineering and regenerative medicine.
