. "Interacts with MAPRE1; this interaction is required for efficient accumulation at microtubule plus ends (By similarity). Interacts with KIF2C at microtubule tips; this interaction increases the affinity of both partners for microtubule plus ends and is required for robust microtubule depolymerization (By similarity). KIF2C phosphorylation by AURKA or AURKB strongly reduces KIF18B-binding (By similarity)." . . .
