ABP50: An actin‐binding elongation factor 1α from Dictyostelium discoideum

This is the authors' abstract. We don't add key points for this paper.

ABP50 is a polypeptide elongation factor 1 alpha from Dictyostelium that is associated with the actin cytoskeleton. Upon chemotactic stimulation, ABP50 undergoes a dramatic cytoplasmic redistribution into newly formed surface projections and in vitro binds to and bundles actin filaments. Many questions are raised by this interaction pertaining to the spatiotemporal regulation of protein synthesis and cytoskeletal organization by extracellular signals.
