Summary: Enables core promoter sequence-specific DNA binding activity. Predicted to be involved in DNA-templated transcription termination; positive regulation of RNA splicing; and transcription by RNA polymerase II. Located in euchromatin and nucleus. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Orthologous to human POLR2A (RNA polymerase II subunit A). [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.
