Component of the PAN1 actin cytoskeleton-regulatory complex required for the internalization of endosomes during actin-coupled endocytosis. The complex links the site of endocytosis to the cell membrane-associated actin cytoskeleton. Mediates uptake of external molecules and vacuolar degradation of plasma membrane proteins. Plays a role in the proper organization of the cell membrane-associated actin cytoskeleton and promotes its destabilization. Component of the PAN1 actin cytoskeleton-regulatory complex. Interacts with ABP1, KRE6, LAS17, LSB5, RSP5, RVS167, VPS1 and YSC84. Cytoplasmic and cortical actin patches. Is associated with cortical actin patches in its dephosphorylated form and dissociates upon phosphorylation by PRK1. Phosphorylated by PRK1. Present with 952 molecules/cell in log phase SD medium. Belongs to the SLA1 family.
