Abstract excerpt
The glucose-regulated protein GRP94 is a molecular chaperone that is located in the endoplasmic reticulum (ER). Here, we demonstrate in pull down experiments an interaction between GRP94 and sucrase-isomaltase (SI), the most prominent disaccharidase of the small intestine. GRP94 binds to SI exclusively via its mannose-rich form compatible with an interaction occurring in the ER. We have also examined the...
