POPDC proteins participate in multiple protein complexes and subcellular compartments. Shown here is a schematic depiction of the different protein complexes that POPDC1 is part of. Most of the interacting proteins are localized to the sarcolemma. However Popdc1 and Popdc2 are also localized to specialized membrane compartments such as caveolae, t-tubuli, nuclear envelope, nucleoplasm and intercalated disk. While a ventricular cardiac myocyte has been depicted here, some of the protein complexes have not been characterized in this cell type. The interacting proteins in the nuclear envelope and t-tubules have not yet been identified.
