Enables histone serine kinase activity and ubiquitin protein ligase binding activity. Acts upstream of or within several processes, including microtubule cytoskeleton organization; positive regulation of oocyte maturation; and protein localization to centrosome. Located in axon hillock; microtubule cytoskeleton; and nucleus. Is expressed in several structures, including alimentary system; bone; brain; eye; and genitourinary system. Human ortholog(s) of this gene implicated in colorectal cancer; ovarian cancer; and uterine cancer. Orthologous to human AURKA (aurora kinase A). [provided by Alliance of Genome Resources, Apr 2022]
