The WHHERE coactivator complex is required for retinoic acid-dependent regulation of embryonic symmetry

Abstract

Retinoic acid (RA) regulates the maintenance of somitogenesis symmetry. Here, the authors use a proteomic approach to identify a protein complex of Wdr5, Hdac1, Hdac2 that act together with RA and coactivator Rere/Atrophin2 and a histone methyltransferase Ehmt2 to regulate embryonic symmetry.
