Summary
Enables RNA polymerase II-specific DNA-binding transcription factor binding activity. Predicted to be involved in RNA polymerase II preinitiation complex assembly and positive regulation of transcription initiation by RNA polymerase II. Predicted to be located in cell junction and nucleoplasm. Predicted to be part of transcription factor TFIIA complex and transcription factor TFIID complex. Is expressed in head. Orthologous to human GTF2A2 (general transcription factor IIA subunit 2). [provided by Alliance of Genome Resources, Nov 2024]
Expression

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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) lacks an exon in the internal coding region, which leads to a translational frameshift, compared to variant 1. The encoded isoform (2) has a shorter and distinct C-terminus, compared to isoform 1.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (4) contains an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
