Web3 de ago. de 2024 · The accumulated HIF-1α is then transferred to the nucleus, forms dimers with HIF-1β (ARNT), and interacts with the transcriptional coactivator CBP/p300 to form a transcription initiation complex that recognizes hypoxia response elements (HREs) in the promoters of target genes to induce transcription (23,39,44,50) (Figure 1). WebHIF-1 is where p300 interacts with the -subunit to fully activate the HIF-1 transcription factor. To confirm that the increase in transcriptional activity of HIF-1 was indeed attributable to …
