Binding of heat-shock protein 70 (hsp70) to tubulin.

Binding of heat-shock protein (hsp70) to polymerized tubulin has been investigated by in vitro experiments. The tubulin region involved in binding to hsp70 corresponds to the carboxy-terminal residues 431-444, also involved in the association with other microtubule-associated proteins (MAPs). Additionally, the putative tubulin binding motif in the hsp70 protein contains a sequence related to the motif described for MAP1B protein.
