Subcellular colocalization of vacuolar H+-ATPase and c-src. Cells maintained on tissue culture plates for 3 d were lysed (S 0), and the lysate was centrifuged at 1,000 g to remove nuclei and large cell debris. Supernatant was centrifuged at 27,000 g and the membrane pellet (P 3) was fractionated on a sucrose density gradient. An equal amount of protein from each gradient fraction was subjected to immunoblot using antibodies to c-src, H+-ATPase, and F4/80. GLF, Golgi light; GHF, Golgi heavy; CVCF, crude vesicle fractions.
