^aRefer to Table 1 for mutations. WT, wild type.

^bMitotic chromosome binding activity is expressed as ability to bind to mitotic chromosomes. ON, exclusive colocalization with mitotic chromosomes; Both, E2 protein localized both on and off mitotic chromosomes; OFF, exclusion from mitotic chromosomes; No E2, no E2 expression; %, percentage of mitotic cells with E2 bound to mitotic chromosome (ON and Both).
