| Research Abstract |
We examined ERES localization within the peripheral ER, finding that ERES localize on high-curvature ER domains where curvature-stabilizing protein Rtn1 is present. In mutant cells having fewer high-curvature ER domains, ERES accumulate at the remaining high-curvature ER domains on the edge of expanded ER sheets. We propose that membrane curvature is a key geometric feature for the regulation of ERES localization.
