Genes affected

USP3 (HGNC:12626): (ubiquitin specific peptidase 3) Enables histone binding activity and thiol-dependent deubiquitinase. Involved in several processes, including DNA repair; histone deubiquitination; and regulation of protein stability. Located in several cellular components, including Flemming body; cytoplasmic ribonucleoprotein granule; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

USP3 (HGNC:):
