Coronin 1 was first isolated from Dictyostelium, but similar proteins have been identified in many species and individual cell types. The coronin-like protein in yeast promotes actin polymerization and also interacts with microtubules. Dictyostelium mutants lacking coronin are impaired in cytokinesis and all actin-mediated processes. Analysis of coronin-GFP fusions and knockout mutants shows that coronin participates in the remodelling of the cortical actin cytoskeleton that is responsible for phagocytosis and macropinocytosis. Likewise, in mammalian neutrophils, a coronin-like protein is also associated with the phagocytic apparatus. Coronin 1 binds actin and is found in noninfected macrophages, localised to the cortical microtubule network; in mycobacteria-infected macrophages, progressively relocalized and retained around the mycobacterial phagosomes.
