Fig. 7. Protein 4.1R associates with
- and
-tubulin. (A) Coomassie-stained gels showing the purified (P) GST fusion proteins used in the binding assays and the eluates (E) from glutathione beads coupled with the indicated GST fusion proteins and incubated with COS-7 cell extracts. (B) Immunoblots of the eluates revealed with antibodies against
- and
-tubulin. Positions of molecular-weight markers are indicated on the left.
