Kinesin family member KIF18A is a human protein encoded by the KIF18A gene. [5] [6] It is part of the kinesin family of motor proteins.
KIF18A is a plus-end directed motor protein, and migrates to the plus ends of the spindle during early mitosis. It first accumulates there during prophase and metaphase, and is depleted during anaphase. [7]
KIF18a(-/-) knockout in mice results in complete sterility in males, but not females, due to abnormal development of the seminiferous tubules. [8] The mice were otherwise normal, suggesting KIF18a is not essential for cell divisions in non-germ cells.
KIF18A has been considered as a cancer target because it is overexpressed in many cancer types and mouse studies suggest it is dispensable in somatic cells. [9] As such, small molecule inhibitors of KIF18A have been developed to block its activity. [9]
