Figure 1. Location of membrane contact sites.
A. Endoplasmic reticulum (ER) - plasma membrane (PM) B. ER - Mitochondria (Mito) C. ER - Late endosome (LE)/ multivesicular bodies (MVB) and ER - lysosome. In yeast there are contacts between the nucleus and vacuole. D. ER – Golgi complex. E. ER and chloroplast (chloro). F. ER – peroxisome (Pex) G. ER and lipid droplets (LD). H. Contact sites between the inner and outer membranes of mitochondria and chloroplasts. Similar contacts are also found in Gram negative bacteria (not shown).
