Summary
Contributes to DNA-directed RNA polymerase activity. Involved in tRNA transcription by RNA polymerase III and transcription by RNA polymerase I. Part of RNA polymerase I complex and RNA polymerase III complex. Used to study Treacher Collins syndrome 2 and leukodystrophy. Human ortholog(s) of this gene implicated in Treacher Collins syndrome 2. Orthologous to human POLR1D (RNA polymerase I and III subunit D). [provided by Alliance of Genome Resources, Jul 2025]
