Summary
Predicted to enable DNA-directed 5'-3' RNA polymerase activity; DNA/RNA hybrid binding activity; and zinc ion binding activity. Predicted to contribute to RNA polymerase III activity. Predicted to be involved in positive regulation of innate immune response; positive regulation of interferon-beta production; and snRNA transcription by RNA polymerase III. Predicted to be located in cytoplasm. Predicted to be part of RNA polymerase III complex. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease and hypomyelinating leukodystrophy 8. Orthologous to human POLR3B (RNA polymerase III subunit B).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
