Intracellular localization of p49 and NDUFAB1. Fluorescent images of H9C2 cells transfected with NDUFAB1-RFP expression plasmids (a, top left) and RFP control (b, top right), demonstrate both nuclear and cytoplasmic distribution. The p49-GFP fusion protein appears to be primarily localized within the nucleus, especially the nucleoli (c, bottom left). The GFP-only control protein is distributed evenly throughout the cells (d, bottom right). GFP = green fluorescent protein; RFP red fluorescent protein.
