Other CTAs involved in proper cell abscission during cytokinesis (Centrosomal protein 55-CEP55 [83] and M-phase phosphorotein1-MPHOSPH1 [96]) and a group identified to positively regulate mitosis but the exact functions of which have yet to be elucidated (coiled-coiled domain-containing protein 110-CCDC110, FMR1 neighbour protein-FMR1NB, nuclear RNA export factor 2-NXF2, testis cancer centrosome-related protein-TCC52 and opa interacting protein 5-OIP5) [84,97,98] were also subsequently added to this growing list of cell-cycle regulatory CTAs. Here, CCDC110 is linked to testicular cancer.
