The endoplasmic reticulum (ER) is a cellular organelle in charge of multiple important cellular functions including the biosynthesis and folding of newly synthesized proteins destined for secretion such as insulin. conditions such as (Inositol requiring enzyme 1) and ATF6 (activating transcription element 6). Under unstressed conditions these three proteins are held from the abundant ER… Continue reading The endoplasmic reticulum (ER) is a cellular organelle in charge of
