WebHIF-1α and HIF-1β can dimerize, and bind to the enhancer region to increase its promoter activity. HIF-1 commonly has the binding site “RCGTG” in the enhancer region.41,42,44 Web4 de set. de 2024 · Since YAP has no DNA-binding domains, and binds to its target genes promoters by interacting with DNA-binding transcription factors [33, 34], so we focused on HIF-1a and analyzed HIF-1a and PKM2 gene sequence. Finally, we found a candidate HRE (HIF-1a binding site 5’-ACGTG-3′) in PKM2 promoter.
Web20 de jun. de 2024 · The asparagine residues of HIF-α subunits are also hydroxylated by factors inhibiting HIFs (FIHs), which inhibits the binding of HIF with co-activators p300/CREB-binding protein. WebNational Center for Biotechnology Information
WebTo understand how HIF-1α regulates ASAP3 expression, we identified two potential HIF-1α–binding sites (HRE1-2) within the promoter and upstream of the transcription start site . To determine whether HIF-1α binds these HREs, we performed a CHIP assay using anti-HIF-1α antibodies in A549 cells cultured under hypoxic (1.5% O 2 ) or normoxic (21% O … Web15 de fev. de 2024 · Hydroxylation of HIF-1α provides an essential binding site for the E3 ligase von Hippel–Lindau (VHL), leading to the ubiquitination and proteasome-mediated degradation of HIF-1α [6, 7].
Web1 de mai. de 2002 · The structure shows that a 15–amino acid portion of HIF-1α (residues 561 to 575) adopts an extended, β strand–like conformation ( Fig. 1 A). It binds pVHL in a bipartite manner, with two discontinuous HIF-1α segments interacting with a continuous site on pVHL.
