Summary: Enables histone binding activity. Involved in several processes, including metaphase plate congression; mitotic spindle assembly checkpoint signaling; and mitotic spindle organization. Located in microtubule cytoskeleton; nucleus; and polytene chromosome interband. Is expressed in several structures, including adult head; embryonic brain; embryonic/larval digestive system; and energid. [provided by Alliance of Genome Resources, Apr 2022]
