This protein forms a tetrameric complex with the alpha subunit, and stimulates transcription of target genes. The encoded protein may be involved in activation of cytochrome oxidase expression and nuclear control of mitochondrial function. The crystal structure of a similar protein in mouse has been resolved as a ternary protein complex. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008] 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.
