- Description
- Enables DNA-directed 5'-3' RNA polymerase activity. Involved in neural crest cell migration and neural crest formation. Predicted to be located in chromosome and nucleolus. Predicted to be part of RNA polymerase I complex. Is expressed in several structures, including alar plate midbrain region; eye; liver; musculature system; and optic tectum. Used to study Treacher Collins syndrome. Human ortholog(s) of this gene implicated in Treacher Collins syndrome 4. Orthologous to human POLR1B (RNA polymerase I subunit B).
