Exosc4 Gene Summary [Mouse]
Predicted to enable RNA binding activity. Predicted to be involved in DNA deamination; RNA metabolic process; and positive regulation of cell growth. Predicted to act upstream of or within defense response to virus. Predicted to be located in cytosol; euchromatin; and nucleoplasm. Predicted to be part of cytoplasmic exosome (RNase complex) and nuclear exosome (RNase complex). Predicted to be active in nucleolus. Is expressed in several structures, including early conceptus; gonad; liver; metanephros; and muscle tissue. Orthologous to human EXOSC4 (exosome component 4).

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 Exosc4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- 3' exoribonuclease family, domain 2
- RNase PH-like 3'-5' exoribonucleases
- mRNA 3' UTR binding
- protein binding
