. "Associates with the microtubule network at the growing distal tip (the plus-end) of microtubules, probably through interaction with MTUS2/TIP150 and MAPRE1. Association with microtubule plus ends is also mediated by interaction with KIF18B (By similarity). Centromeric localization requires the presence of BUB1 and SGOL2 (By similarity)." . . . . . . . .
