title: OS-9: another piece in the HIF complex story.
abstract: In this issue of Molecular Cell, the Semenza group reports that OS-9, a common protein of unassigned function, promotes the O2-dependent degradation of hypoxia inducible factor (HIF) via binding to both HIF and the HIF prolyl-hydroxylases, implying that OS-9 is part of a multiprotein complex involved in the hypoxic response (Baek et al., 2005).
