G endoplasmic reticulum

Endoplasmic reticulum, continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins. All eukaryotic cells contain an endoplasmic reticulum The endoplasmic reticulum is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits - rough endoplasmic reticulum, and smooth endoplasmic reticulum. The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae, and tubular structures in the SER. The membranes of the ER are. G-Endoplasmic Reticulum. The endoplasmic reticulum is made of two parts. The Rough ER is bumpy because of its ribosome coating. It resembles a maze by its look, and uses flattened sacs to produce and export proteins, glycoproteins, and hormones. Its other part is the Smooth ER. It produces lipids and steroids, without the use of proteins What is Endoplasmic Reticulum? Endoplasmic reticulum transpires in two forms: a type with ribosome-studded surface and another with a smooth surface. The latter is called the smooth endoplasmic reticulum, and the former is called the rough endoplasmic reticulum. These membranes form continuous folds, eventually joining the outer layer of the nuclear membrane. Except for sperm cells and red blood cells, the endoplasmic reticulum is observed in every other type of eukaryotic cell

The endoplasmic reticulum (ER) is a large organelle made of membranous sheets and tubules that begin near the nucleus and extend across the cell. The endoplasmic reticulum creates, packages, and secretes many of the products created by a cell. Ribosomes, which create proteins, line a portion of the endoplasmic reticulum. Endoplasmic Reticulum Overvie Hence it is referred as a rough endoplasmic reticulum. The smooth endoplasmic reticulum consists of tubules, which are located near the cell periphery. This network increases the surface area for the storage of key enzymes and the products of these enzymes. Rough endoplasmic reticulum synthesizes proteins, while smooth endoplasmic reticulum synthesizes lipids and steroids. It also metabolizes carbohydrates and regulates calcium concentration, drug detoxification, and attachment of receptors. Efficient export of the vesicular stomatitis virus G protein from the endoplasmic reticulum requires a signal in the cytoplasmic tail that includes both tyrosine-based and di-acidic motifs The vesicular stomatitis virus (VSV) G protein is a model transmembrane glycoprotein that has been extensively used to study the exocytotic pathway In HEC50 cells, GPR30 (red signal in Fig. 2, H and N) did not colocalize with cadherin (green signal in Fig. 2, G and I) or the Golgi apparatus (green signal in Fig. 2, M and O) but was expressed in the endoplasmic reticulum (yellow signal in Fig. 2L) as evidenced by costaining with antibodies against the endoplasmic reticulum marker KDEL. The endoplasmic reticulum (ER) is the largest, membrane-bound intracellular organelle found in eukaryotic cells (prokaryotes lack membrane-bound organelles). It's a highly dynamic organelle that radiates from the nuclear envelope towards the plasma membrane
