CKAP5

Cytoskeleton-associated protein 5 is a microtubule-associated protein that in humans is encoded by the CKAP5 gene.^[5][6][7] It is the homolog of the Xenopus protein XMAP215^[8] and is also known as ch-Tog.

It has at least two distinct roles in spindle formation: it protects kinetochore microtubules from depolymerization by MCAK (KIF2C), and ch-Tog plays an essential role in centrosomal microtubule assembly, a function independent of MCAK activity.^[9]
