MAPRE3, also known as EB3, is a member of the RP/EB family. MAPRE3 localizes to the cytoplasmic microtubule network and binds APCL. MAPRE3 regulates the dynamics of the microtubule cytoskeleton. It also promotes microtubule growth. MAPRE3 may be involved in spindle function by stabilizing microtubules and anchoring them at centrosomes. MAPRE3 may also play a role in cell migration.
