Exosc9 Gene Summary [Rat]
Enables RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in positive regulation of transcription by RNA polymerase II. Predicted to be located in cytosol and nuclear lumen. Predicted to be part of cytoplasmic exosome (RNase complex) and nuclear exosome (RNase complex). Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 1D. Orthologous to human EXOSC9 (exosome component 9). [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 Exosc9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
