Predicted to enable protein kinase activity. Acts upstream of or within chromosome segregation and positive regulation of intrinsic apoptotic signaling pathway. Located in kinetochore. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in colorectal cancer. Orthologous to human BUB1 (BUB1 mitotic checkpoint serine/threonine kinase). [provided by Alliance of Genome Resources, Apr 2022]
