Receptor: 1. In cell biology, a structure on the surface of a cell (or inside a cell) that selectively receives and binds a specific substance. There are many receptors.
The most common is EPNS (Electro Plated Nickel Silver) but many other symbols are used: 1  EPBM (Electro Plated Britannia Metal). 2  EPCA (Electro Plated Copper Alloy). 3  ESM (Electro Plated Silver Mounts).he most common is EPNS (Electro Plated Nickel Silver) but many other symbols are used: 1  EPBM (Electro Plated Britannia Metal). 2  EPCA (Electro Plated Copper Alloy). 3  ESM (Electro Plated Silver Mounts).
The erythropoietin receptor (EpoR) is a protein that in humans is encoded by the EPOR gene. EpoR is a 59 kDa peptide and is a member of the cytokine receptor family. EpoR pre-exists as dimers which upon binding of a 34 kDa ligand erythropoietin (Epo), changes its homodimerized state.
