Usp3 Gene Summary [Rat]
Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and promoter-specific chromatin binding activity. Involved in negative regulation of transcription by RNA polymerase II. Predicted to be located in several cellular components, including Flemming body; cytoplasmic ribonucleoprotein granule; and nucleoplasm. Predicted to be active in cytoplasm and nucleus. Orthologous to human USP3 (ubiquitin specific peptidase 3). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Usp3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
