EXOSC5 Gene Summary [Human]
Predicted to enable RNA binding activity. Involved in DNA deamination and exonucleolytic catabolism of deadenylated mRNA. Acts upstream of or within defense response to virus. Located in nucleolus; nucleoplasm; and transcriptionally active chromatin. Part of exosome (RNase complex). [provided by Alliance of Genome Resources, Apr 2022]

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 human EXOSC5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
