Component of a cytoskeletal structure that is required for the formation of endocytic vesicles at the plasma membrane level. Could be implicated in cytoskeletal reorganization in response to environmental stresses and could act in the budding site selection mechanism. Binds to actin. Interacts with ABP1, GYL1, GYP5, PCL2 and YBR108W. Phosphorylated redundantly by cyclin-dependent kinase PHO85 in association with PCL1,2-type cyclins or by MAP kinase FUS3. Phosphorylation inhibits interaction with complexes involved in actin cytoskeleton function. Present with 14600 molecules/cell in log phase SD medium.
