Predicted to enable DNA binding activity; DNA-directed 5'-3' RNA polymerase activity; and ribonucleoside binding activity. Predicted to contribute to RNA polymerase I activity. Predicted to be involved in transcription by RNA polymerase I. Located in nucleolus. Expressed in several structures, including intestine. Human ortholog(s) of this gene implicated in Treacher Collins syndrome 4. Is an ortholog of human POLR1B (RNA polymerase I subunit B).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
