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).
EPH. A gene on chromosome 7q32-q36 that encodes a member of the ephrin-A receptor subfamily of receptor tyrosine kinases, which promiscuously bind membrane-bound ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signalling into neighbouring cells. gene on chromosome 7q32-q36 that encodes a member of the ephrin-A receptor subfamily of receptor tyrosine kinases, which promiscuously bind membrane-bound ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signalling into neighbouring cells.
