WebEnzyme-linked receptors are also transmembrane proteins, and the extracellular ligands bind to them on the extracellular side. They comprise a very large family, and a major subclass includes receptor tyrosine kinases that phosphorylate the tyrosine residue on the cytosolic side of these proteins. WebWhen a ligand binds to a cell-surface receptor, the receptor’s intracellular domain (part inside the cell) changes in some way. Generally, it takes on a new shape, which may make it active as an enzyme or let it bind other molecules. The change in the receptor sets off a series of signaling events.
