Genes affected

OTUD7B (HGNC:16683): (OTU deubiquitinase 7B) Enables Lys48-specific deubiquitinase activity and thiol-dependent deubiquitinase. Involved in several processes, including negative regulation of I-kappaB kinase/NF-kappaB signaling; negative regulation of macromolecule metabolic process; and protein deubiquitination. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
