CKAP5
Cytoskeleton-associated protein 5 is a microtubule-associated protein that in humans is encoded by the CKAP5 gene.[3][4][5] It is the homolog of the Xenopus protein XMAP215[6] 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.[7]
Interactions
CKAP5 has been shown to interact with TACC1.[8][9]
