^aNumbers are the mean and standard deviation of at least three independent experiments, n = 300.

^b+, GFP puncta localized to mitochondrial tubules.

^cYeast two-hybrid assays. −, No growth on His or Ade minus medium; +, growth on His but not Ade minus medium; ++, growth on both His and Ade minus media. Growth on Ade minus medium is the more stringent indicator of protein–protein interaction.
