That’s a fancy way of saying that the endoplasmic reticulum is attached to the nucleus itself. The translation is initiated in the cytosol, but a signal peptide guides the nascent protein to the ER where the translation continues. Master key terms, facts, and definitions before your next test with the latest study sets in the Endoplasmic Reticulum Function category. The ER was first noted by Porter, Claude and Fullman in 1945. The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. The endoplasmic reticulum (ehn-duh-PLAZ-mihk rih-TIHK-yuh-luhm), or the ER, is an interconnected network of thin folded membranes. Endoplasmic reticulum (ER), which is an organelle found in eukaryotes, contains flattened membranous sacs, interconnected with each other. 2,secretory proteins. Mechanical support. Function of smooth endoplasmic reticulum in brain cell. Endoplasmic reticulum is the interconnected system of membrane-bounded tubules and vesicles which form irregular reticulum or network in the cytoplasmic matrix.
