Summary
Enables chromatin binding activity. Predicted to be involved in transcription by RNA polymerase II. Predicted to be located in nucleoplasm. Predicted to be part of RNA polymerase II, core complex. Predicted to colocalize with chromosome, telomeric region. Is expressed in several structures, including alimentary system; brain; integumental system; respiratory system; and sensory organ. Orthologous to human POLR2B (RNA polymerase II subunit B). [provided by Alliance of Genome Resources, Nov 2024]

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.
