Abstract

Like in most eukaryotic cells, the plant endoplasmic reticulum (ER) network is physically linked to the plasma membrane (PM), forming ER-PM contact sites (EPCS). The protein complex required for maintaining the EPCS is composed of ER integral membrane proteins (e.g., VAP27, synaptotagmins), PM-associated proteins (e.g., NET3C), and the cytoskeleton. Here, we describe methods for identifying possible EPCS-associated proteins. These include GFP-tagged protein expression followed by image analysis, and immuno-gold labeling at the ultrastructural level. In combination, these methods can be used to identify the localization of putative EPCS proteins as well as used to postulate their subcellular function.
