Calcium (Ca2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum (ER), a cellular organelle that synthesizes and transports proteins, has not been elucidated. This control system of protein quality, known as proteostasis, was put under a micr oscope by researchers to find a more thorough understanding of the process, potentially revealing clues about how to prevent Type 2 diabetes, Alzheimer's and amyotrophic lateral sclerosis (ALS). ...read more read less
