PGAM5 localizes at inner mitochondrial membrane and at the membrane contact sites. a–d STED images of COS7 cells that were either a untransfected or b, c transiently transfected with wild type (WT) or F244E full-length myc-tagged PGAM5. Tom20 was visualized with anti-Tom20 antibody (green), Tim23 with anti-Tim23 antibody (green), and PGAM5 with anti-myc antibody (red). White arrows indicate contact sites between mitochondrial membranes in which myc-tagged PGAM5 was found colocalized with Tom20. Scale bars correspond to 5 µm in a, 5 µm in b, and 1 µm in c. d Upper panels show representative close-up views of PGAM5 localization to the sites of mitochondrial membrane contacts. White arrows indicate sites of PGAM5 (myc, red) overlap with the outer mitochondria membrane marker Tom20 (green)
