Erythrocyte protein 4.1 associates with tubulin.
Protein 4.1 binds to tubulin, as determined by sedimentation and immunoelectron-microscopy analyses, at a molar ratio similar to that described for brain microtubule-associated proteins. The binding site appears to be located at the C-terminal region of tubulin. Experiments performed in situ by adding exogenous protein 4.1 to permeabilized 3T3 cells show that this protein binds to microtubule and nuclear components.
