Endoplasmic reticulum calcium ATPases positively regulate Notch precursor trafficking
In Drosophila, mutations that lead to the loss of function of endoplasmic reticulum membrane calcium ATPase Ca-P60A result in impaired Notch cleavage by furin (although furin is not directly affected) and Notch trafficking to the cell surface. This could be due to Notch misfolding in the endoplasmic reticulum at suboptimal concentrations of calcium.
