Description

Predicted to contribute to RNA polymerase I activity. Involved in embryonic viscerocranium morphogenesis and neural crest cell development. Predicted to localize to RNA polymerase I complex. Human ortholog(s) of this gene implicated in acrofacial dysostosis Cincinnati type. Is expressed in several structures, including alar plate midbrain region; digestive system; nervous system; pectoral fin musculature; and segmental plate. Orthologous to human POLR1A (RNA polymerase I subunit A).
