Abstract: Voltage dependent anion channel (VDAC) is a vital ion channel in mitochondrial outer membranes and its structure was recently shown to be a 19 stranded beta-barrel. However the orientation of VDAC in the membrane remains unclear. We probe here the topology and membrane orientation of yeast Saccharomyces cerevisiae in vivo. Five FLAG-epitopes were independently inserted into scVDAC1 and their surface exposure in intact and disrupted mitochondria detected by immunoprecipitation. Functionality was confirmed by measurements of respiration. Two epitopes suggest that VDAC (scVDAC) has its C-terminus exposed to the cytoplasm whilst two others are more equivocal and, when combined with published data, suggest a dynamic behavior. โข Keywords: Mitochondrial membrane channels
