Predicted to enable microtubule-severing ATPase activity. Involved in several processes, including male meiotic nuclear division; osteoblast differentiation; and osteoblast proliferation. Acts upstream of or within negative regulation of intrinsic apoptotic signaling pathway. Located in nucleus and perinuclear region of cytoplasm. Is expressed in brain ventricular layer and inferior colliculus. Orthologous to human FIGNL1 (fidgetin like 1). [provided by Alliance of Genome Resources, Apr 2022]
