Enteropathogenic Escherichia coli (EPEC), Salmonella typhimurium, and Listeria monocytogenes usurp the actin cytoskeleton for their attachment, internalization and transport within and amongst infected cells. To try to gain a greater understanding of the molecular components utilized by these microbes during their infections we previously concentrated actin‐rich structures generated during EPEC infections (called pedestals) and identified the heat shock cognate 70 protein (Hsc70) as a potential candidate. This multifunctional protein classically acts as a chaperone for the proper folding of a variety of proteins and is involved in uncoating clathrin from coated pits. Here we demonstrated that Hsc70 is recruited to actin structures generated during EPEC, Listeria and Salmonella infections, but not to the same location as clathrin.
