Genes affected

KIF3A (HGNC:6319): (kinesin family member 3A) Enables protein phosphatase binding activity; small GTPase binding activity; and spectrin binding activity. Involved in protein localization to cell junction and protein transport. Located in centriole and centrosome. Part of kinesin II complex. Colocalizes with spindle microtubule.
