Involved in phagocytosis and cell motility. Binds to actin filaments and protects them against depolymerization. Monomer. Binds to F-actin. Accumulates in cell surface projections during movement, phagocytosis and pinocytosis. Detected at the leading edge of the cell during chemotaxis. Expressed throughout development. Seems to consist of two repeat of a full-length coronin. Shows altered chemotaxis and phagocytosis. Cells are slightly smaller, grow more slowly and do not reach the same final density at stationary phase. Affects the infection process by the pathogen L.pneumophila and allows a more efficient internalization of bacteria. Allows a more efficient uptake of dead yeast cells. Belongs to the WD repeat coronin family.
