A 55 kDa protein of transitional endoplasmic reticulum from rat liver binds retinol.
A transitional endoplasmic reticulum fraction from rat liver that responds to retinol by increased formation of 50-70 nm diameter transition vesicles bound retinol. Separation on SDS-PAGE with analysis by fluorography indicated the dominant binding component at 55 kDa. Binding was found with transitional vesicles formed from the transitional endoplasmic reticulum, and the endoplasmic reticulum fractions from which vesicles are derived but not with Golgi apparatus, plasma membranes or cytosol.
