Also known as: BEX2; HBEX2; HGR74-h
Summary: Enables RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in positive regulation of DNA-binding transcription factor activity and positive regulation of transcription by RNA polymerase II. Part of transcription regulator complex. [provided by Alliance of Genome Resources, Dec 2024]
Annotation information: Note: The BEX1 and BEX2 genes appear to have undergone gene conversion, exchanging bits of coding sequence with each other. This complicates determination of orthologs in other species. For this reason, gene name assignments may not be consistent between species. [06 Dec 2023]
Expression: Biased expression in brain (RPKM 178.4), testis (RPKM 38.4) and 3 other tissues See more
Orthologs: mouse all

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.
