Jmjd6 catalyses lysyl-hydroxylation of U2AF65, a protein associated with RNA splicing.
The finding that the metazoan hypoxic response is regulated by oxygen-dependent posttranslational hydroxylations, which regulate the activity and lifetime of hypoxia-inducible factor (HIF), has raised the question of whether other hydroxylases are involved in the regulation of gene expression. We reveal that the splicing factor U2 small nuclear ribonucleoprotein auxiliary factor 65-kilodalton subunit (U2AF65) undergoes posttranslational lysyl-5-hydroxylation catalyzed by the Fe(II) and 2-oxog...Expand abstract
