      Calle Mustienes, Elisa de la; Gómez Skarmeta, José Luis (2000)
      Ligand-bound nuclear receptors (NRs) recruit cofactors such as members of the p160 family and CREB-binding protein (CBP) to activate transcription. We have cloned the Xenopus homologue of the human transcription intermediary ...
    • Xyloglucan fucosyltransferase, an enzyme involved in plant cell wall biosynthesis 
      Perrin, Robyn M.; DeRocher, Amy E.; Bar-Peled, Maor; Zeng, Weiqing; Norambuena Morales, Lorena; Orellana, Ariel; Raikhel, Natasha V.; Keegstra, Kenneth (1999)
      Cell walls are crucial for development, signal transduction, and disease resistance in plants. Cell walls are made of cellulose, hemicelluloses, and pectins. Xyloglucan (XG), the principal load-bearing hemicellulose of ...
