Summary
Enables transcription cis-regulatory region binding activity. Acts upstream of or within positive regulation of transcription by RNA polymerase II. Located in nucleus. [provided by Alliance of Genome Resources, Jun 2025]
Annotation information
Note: In August, 2008, the nomenclature of the GA binding protein transcription factors was clarified. The gene on Hsa1q was named GABPB2 and the gene on Hsa15q was named GABPB1. [24 Sep 2008]
Expression
Ubiquitous expression in testis (RPKM 4.7), ovary (RPKM 3.2) and 25 other tissues See more

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.
