This entry represents the C-terminal domain of protein furry (Fry). Fry plays a crucial role in the structural integrity of mitotic centrosomes and in the maintenance of spindle bipolarity. This domain binds to polo-like kinase 1 (Plk1) through the polo-box domain (PBD) of Plk1 in a manner dependent on the cyclin-dependent kinase 1-mediated Fry phosphorylation, promoting Plk1 activity during early mitosis. Fry also binds to Aurora A and may function as a scaffold promoting the interaction between AURKA and PLK1, thereby enhancing AURKA-mediated PLK1 phosphorylation [].
