  • Publication number: 20180271851
    Abstract: A novel class of hydroxylases is described having the amino acid sequence of SEQ ID NO: 2, 4, 6 and 8, and variants and fragments thereof having HIF hydroxylation activity. The polypeptides of the invention have in particular prolyl hydroxylase activity. An assay method monitors the interaction of the HIF hydroxylase with a substrate. Modulators of HIF hydroxylase are provided for use in the treatment of a condition associated with increased or decreased HIF levels or activity or for the treatment of a condition where it is desirable to modulate HIF levels or activity.
