GroEL is a type of molecular chaperone that belongs to the family of heat shock proteins (Hsp60). It plays a crucial role in assisting the proper folding of proteins within cells. This protein is particularly important in conditions where cells are under stress, such as high temperature or other physiological stresses, which can cause proteins to misfold. GroEL works in conjunction with its co-chaperonin, GroES, to form a complex that provides an isolated environment for proteins to fold correctly.
