RER or rough endoplasmic reticulum is found on attached on the nucleus and does the work mainly of protein synthsesis.We call the RER rough because it has a special feature that is the ribosomes attached to themselves. It is well known as according to research conducted by experts in the field of cell biology,that Rough Endoplasmic Reticulum Function or RER function is the synthesis of special kind of proteins.Thet also process these proteins and also release various kinds of enzymes which play an important role in the metabolism of the animal as well as plant cell.Thses membranous structures found attached to the nucleus and also found floating in the cytoplasm have been assigned various functions. The ribosomes which are found attached to them have to manufacture specific proteins which are transported to various parts of the cell with the help of the rough endoplasmic reticulum. You can conduct a thorough search on the internet if you are not aware of the functions of the RER by just typing in the related keyword on the Google search engine and you can get all the details regarding the same displayed before you in a short time period.

The Rough Endoplasmic Reticulum Function is mainly to manufacture two kinds of proteins, on which is attached to the membrane of the endoplasmic reticulum. The other kind of protein is easily soluble or we can say that it easily gets mixed with water. They are transported to the lumen with the help of the cytoplasm and reach the required site. Proteins are mainly composes of amino acids. We can say that the information regarding the manufacture of a specific kind of protein is coded in the ribosomes.Ribosomes are regarded as autonomous units responsible for protein synthsesis.Thus we should understand the functions of ribosomes before we come to the functions of endoplasmic reticulum. It is well known that Ribosome's play an important role in protein synthesis and in the formation of enzymes. These enzymes which are synthesized within the ribosomes play an important role in various chemical reactions which occur within the cell. It is estimated that the endoplasmic reticulum and that to the RER is responsible for the formation of various kinds of membranes and is also found to be associated with the Golgi apparatus at times. Scientists are of the opinion that if there were no such units as the ribosome's found attached to the ER, then proteins would not be synthesized which are the main buildings blocks of cell and play a vital role in formation of the structural components of a cell.
