Involved in cytokinesis and spindle organization. May play a role in actin cytoskeleton organization and microtubule stabilization and hence required for proper cell adhesion and migration (By similarity). May interact with both microtubules and actin cytoskeleton. Colocalizes with beta-tubulin, acetylated alpha-tubulin and F-actin. Also observed in a ring around gamma-tubulin containing centrioles possibly in the microtubule organizing center (By similarity). Belongs to the cytospin-A family.
