Exosc1 Gene Summary [Mouse]
Predicted to enable RNA binding activity. Predicted to be involved in RNA catabolic process and RNA processing. Predicted to be located in cytosol and nucleolus. Predicted to be part of nuclear exosome (RNase complex). Predicted to be active in cytoplasm. Is expressed in several structures, including cerebral cortex; early conceptus; gonad; liver; and submandibular gland primordium. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 1F. Orthologous to human EXOSC1 (exosome component 1). [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 Exosc1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
