Alpha tubulin binds directly to mGluR7a. Protein overlay blots probed with anti-GST antibody show that the GST-mGluR7a CT fusion protein binds specifically to purified tubulin (Tub, 10 μg; 60 kDa) and calmodulin (CaM, 1 μg; 17 kDa), but not to bovine serum albumin (BSA, 10 μg; 66 kDa) (a). Control experiments show that the GST fusion protein (1 μg; 27 kDa) does not bind to tubulin or calmodulin, but is specifically recognized by the anti-GST antibody (b).
