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 …
