Xrn2 Gene Summary [Rat]
Predicted to enable several functions, including RNA exonuclease activity, producing 5'-phosphomonoesters; identical protein binding activity; and transcription termination site sequence-specific DNA binding activity. Involved in hippocampus development; neuron differentiation; and retina development in camera-type eye. Predicted to be located in aggresome; nucleolus; and nucleoplasm. Predicted to be active in nucleus. Biomarker of status epilepticus. Human ortholog(s) of this gene implicated in adenoid cystic carcinoma and lung cancer. Orthologous to human XRN2 (5'-3' exoribonuclease 2). [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 Xrn2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
