| endoplasma | <biology> Same as Entoplasm and Endosarc. Origin: NL. See Endoplasm. Source: Websters Dictionary (01 Mar 1998) |
| endoplasmic | Referring to the endoplasm. (05 Mar 2000) |
| endoplasmic reticulum | <cell biology> Membrane system that ramifies through the cytoplasm. The membranes of the endoplasmic reticulum are separated by 50-200 nm and the cisternal space thus enclosed constitutes a separate compartment. The Golgi region is composed of flattened sacs of membrane that together with endoplasmic reticulum and lysosomes constitute the GERL system. See: smooth endoplasmic reticulum, rough endoplasmic reticulum. (18 Nov 1997) |
| endoplasmic reticulum, rough | A type of endoplasmic reticulum (er) where polyribosomes are present on the cytoplasmic surfaces of the er membranes. This form of er is prominent in cells specialised for protein secretion and its principal function is to segregate proteins destined for export or intracellular utilization. (12 Dec 1998) |
| endoplasmic reticulum, smooth | A type of endoplasmic reticulum lacking associated ribosomes on the membrane surface. It exhibits a wide range of specialised metabolic functions including supplying enzymes for steroid synthesis, detoxification, and glycogen breakdown. In muscle cells, smooth endoplasmic reticulum is called sarcoplasmic reticulum. (12 Dec 1998) |
| endoplasmin | <protein> most abundant protein in microsomal preparations from mammalian cells (100 fold more concentrated in endoplasmic reticulum than elsewhere). A glycoprotein (100 kD) with calcium binding properties. Same as glucose related protein. A member of the hsp90 family of heat-shock proteins. (18 Nov 1997) |
