Abstract:
:A mitochondrial fraction, purified from pig brain, was found to contain associated polypeptides with the same electrophoretic migration and isoelectric points as the alpha- and beta-tubulin subunits present in brain microtubules. When analyzed by Western blotting these polypeptides reacted specifically with purified tubulin antibodies. The tubulin-like proteins were then visualized in mitochondrial membranes by protein A-gold complexes after the incubation of purified mitochondria with tubulin antibodies. When membrane and microtubule proteins were compared by isoelectric focussing and two-dimensional gel electrophoresis, differences were observed in the patterns of tubulin isoforms. An additional polypeptide, with the electrophoretic migration of beta-tubulin but the isoelectric point of alpha-tubulin, was found to be enriched in the mitochondrial fraction. This peptide had several Staphylococcus aureus V8 protease peptides in common with alpha-tubulin and may result from a posttranslational modification of that subunit.
