Genes affected

KIF20B (HGNC:7212): (kinesin family member 20B) Enables several functions, including WW domain binding activity; plus-end-directed microtubule motor activity; and protein homodimerization activity. Involved in positive regulation of cell population proliferation and positive regulation of cytokinesis. Located in several cellular components, including microtubule cytoskeleton; midbody; and nuclear lumen. [provided by Alliance of Genome Resources, Apr 2022]
