KIF4A and neoplasm: In addition, KIF4A provides power to the movement of intracellular organs such as microtubules and plays a key role in anaphase; its abnormalities can lead to abnormal mitotic checkpoints and DNA damage repair processes, as well as chromosomal instability and the formation of aneuploidy, which can cause cellular abnormal proliferation and differentiation leading to tumor formation [29, 30].
