WebHIF1b, or the aryl-hydrocarbon-nuclear receptor trans-locator [ARNT].2 Active HIF is termed by its (1)alpha subunit; hence, HIF1 is the active transcription factor consisting of HIF1a and ARNT, HIF2 is the dimer of HIF2a and ARNT, etc. HIF1 and HIF2 are the major hypoxia-inducible factors in humans, mice, and rats. Web24 de jul. de 2012 · HIF1A and HIF2A are the best-known substrates for the product of the VHL gene (pVHL). In normoxic conditions, specific proline residues on HIF1A and HIF2A are hydroxylated; this allows pVHL to bind them. Conversely, under hypoxic condi-tions, pVHL cannot bind and the HIFA subunits are stabilized. A common subunit known as …
