Fig. 5. The subcellular localization of Bro1 requires ESCRT-III components. (A,B)
Subcellular fractionation and western blotting was performed as described in
the legend to Fig. 4A. (C) The
P13 fraction was collected from vps4
cells, then resuspended
in buffer containing 1% Triton X-100 and separated by centrifugation at
100,000 g for 1 hour into a soluble fraction (S100) and a
pellet fraction (P100). The total protein content of each fraction was
resolved by SDS-PAGE and examined by western blotting.
