Kinesin family member KIF18A is a humanprotein encoded by theKIF18Agene.[5][6] It is part of thekinesin family ofmotor proteins.

Function

[edit]

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 theseminiferous tubules.[8] The mice were otherwise normal, suggesting KIF18a is not essential for cell divisions in non-germ cells.

Therapeutic Target

[edit]

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]
