Anti-POLR1E Antibody Picoband® Biotin Conjugated

Predicted to enable DNA binding activity and RNA polymerase I general transcription initiation factor binding activity. Involved in nucleolar large rRNA transcription by RNA polymerase I and transcription initiation at RNA polymerase I promoter. Located in fibrillar center and nucleoplasm. Part of RNA polymerase I complex.
