GtoPdb Ligand ID: 989

Abbreviated name: ET-1
Comment: Endothelin-1 is a 21-amino acid peptide produced in a variety of tissues including endothelial and vascular smooth-muscle cells, neurons and astrocytes in the central nervous system, and endometrial cells. It acts as a modulator of vasomotor tone, cell proliferation, and hormone production (for reviews see [1] and [2] ). As peptides defined by SMILES strings PubChem contains a number of alternative CIDs either with the name "Endothelin-1" and/or Mw 2491.914. Our choice of PubChem CID 16212950 reflects the majority of sources submitting substance structures and assay data.
Species: Human, Mouse, Rat
