Predicted to enable RNA polymerase binding activity. Predicted to be involved in several processes, including cellular response to lipopolysaccharide; poly(A)+ mRNA export from nucleus; and positive regulation of polynucleotide adenylyltransferase activity. Located in nuclear inclusion body. Human ortholog(s) of this gene implicated in oculopharyngeal muscular dystrophy. Orthologous to human PABPN1 (poly(A) binding protein nuclear 1).
