Parn Gene Summary [Rat]
Predicted to enable several functions, including poly(A)-specific ribonuclease activity; protein kinase binding activity; and telomerase RNA binding activity. Predicted to be involved in RNA metabolic process; regulation of nucleobase-containing compound metabolic process; and regulation of telomerase RNA localization to Cajal body. Is active in glutamatergic synapse and postsynapse. Human ortholog(s) of this gene implicated in autosomal recessive dyskeratosis congenita 6. Orthologous to human PARN (poly(A)-specific ribonuclease). [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 Parn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
