Exosc8 Gene Summary [Mouse]
Predicted to enable identical protein binding activity and mRNA 3'-UTR AU-rich region binding activity. Predicted to be involved in RNA metabolic process. Predicted to be located in chromosome; cytosol; and nuclear lumen. Predicted to be part of cytoplasmic exosome (RNase complex) and nuclear exosome (RNase complex). Is expressed in several structures, including alimentary system; brain; genitourinary system; immune system; and integumental system. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 1C. Orthologous to human EXOSC8 (exosome component 8). [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 mouse Exosc8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
