Genes affected

KLHL22 (HGNC:25888): (kelch like family member 22) Enables 14-3-3 protein binding activity. Involved in several processes, including cellular protein metabolic process; cellular response to leucine; and mitotic spindle assembly checkpoint signaling. Located in several cellular components, including cytosol; intercellular bridge; and microtubule cytoskeleton. Part of Cul3-RING ubiquitin ligase complex. Colocalizes with lysosome and nucleus.
