Reaction: Nuclear PHD1,3 hydroxylates proline residues on HIF1A
Proline hydroxylases PHD1 (EGLN2) and PHD3 (EGLN3) located in the nucleus (Metzen et al. 2003) hydroxylate HIF1A at proline-402 and proline-564 (Buick and McKnight 2001, Jaakkola et al. 2001, Ivan et al. 2001, Ivan et al. 2002, Berra et al. 2003, Hirsila et al. 2003, Appelhoff et al. 2004, Tuckerman et al. 2004, Fedulova et al. 2007, Tian et al. 2011). The amount of hydroxylation occurring in the nucleus is controversial. Most hydroxylation is believed to occur in the cytosol.
