FIG. 2.

Representative immunoblots are presented for tubulins and motor proteins in P3 pellets of control and HD (400 and 175 mg/kg/day dose rates) microtubule preparations. Proteins were loaded on gels at 0.25–10 μg per lane. The corresponding immunoblots from supernatant preparations did not reveal HD-induced changes in protein distribution (data not shown). AMPPNP refers to the protocol used for preparation of these fractions (see “Materials and Methods” section). Respective MWs for individual proteins or peptides are presented to the right of the immunoblots.
