Pabpn1 Gene Summary [Mouse]
Enables RNA polymerase binding activity. Involved in MAPK cascade; cellular response to lipopolysaccharide; and positive regulation of polynucleotide adenylyltransferase activity. Located in nucleus. Part of ribonucleoprotein complex. Is expressed in central nervous system; sensory organ; and thymus. Used to study oculopharyngeal muscular dystrophy. Human ortholog(s) of this gene implicated in oculopharyngeal muscular dystrophy. Orthologous to human PABPN1 (poly(A) binding protein nuclear 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 Pabpn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
