Coronin; cortical actin cytoskeletal component that associates with the Arp2p/Arp3p complex to regulate its activity; plays a role in regulation of actin patch assembly; binds directly to Aim7p, forms a high affinity ternary Crn1-Gmf1-Arp2/3 complex, and binds to F-actin branch junctions to synergistically enhance Aim7p-mediated actin filament debranching
