Purified recombinant hARD1 does not catalyse acetylation of Lys532 of HIF-1alpha fragments in vitro.
In humans, many responses to hypoxia including angiogenesis and erythropoiesis are mediated by the alpha/beta-heterodimeric transcription factor hypoxia inducible factor (HIF). The stability and/or activity of human HIF-1alpha are modulated by post-translational modifications including prolyl and asparaginyl hydroxylation, phosphorylation, and reportedly by acetylation of the side-chain of Lys532 by ARD1 (arrest defective protein 1 homologue), an acetyltransferase. Using purified recombinant ...Expand abstract
