  • A p120-catenin-CK1epsilon complex regulates Wnt signaling
    Casagolda, David; Valle Pérez, Beatriz del; Valls, Gabriela; Lugilde, Ero; Vinyoles, Meritxell; Casado Vela, Juan; Solanas, Guiomar; Batlle Gómez, Eduard; Reynolds, Albert B.; Casal, José Ignacio; García de Herreros, Antonio; Duñach, Mireia (Company of Biologists, 2010)
    p120-catenin is an E-cadherin-associated protein that modulates E-cadherin function and stability. We describe here that p120-catenin is required for Wnt pathway signaling. p120-catenin binds and is phosphorylated by CK1ε ...
  • Activation of CK1ɛ by PP2A/PR61ɛ is required for the initiation of Wnt signaling
    Vinyoles, Meritxell; Valle Pérez, Beatriz del; Curto, Josué; Padilla, Mary; Villarroel, Aida; Yang, J.Y.; García de Herreros, Antonio; Duñach, Mireia (Springer Nature, 2017)
    Canonical Wnt signaling induces the stabilization of β-catenin, its translocation to the nucleus and the activation of target promoters. This pathway is initiated by the binding of Wnt ligands to the Frizzled receptor, the ...
  • CK1ε and p120-catenin control Ror2 function in noncanonical wnt signaling
    Curto, Josué; Valle Pérez, Beatriz del; Villarroel, Aida; Fuertes, Guillem; Vinyoles, Meritxell; Peña, Raúl; García de Herreros, Antonio; Duñach, Mireia (Wiley, 2018)
    Canonical and noncanonical Wnt pathways share some common elements but differ in the responses they evoke. Similar to Wnt ligands acting through the canonical pathway, Wnts that activate the noncanonical signaling, such ...
  • Multivesicular GSK3 sequestration upon wnt signaling is controlled by p120-catenin/cadherin interaction with LRP5/6
    Vinyoles, Meritxell; Valle Pérez, Beatriz del; Curto, Josué; Viñas Castells, Rosa, 1985-; Alba Castellón, Lorena, 1984-; García de Herreros, Antonio; Duñach, Mireia (Elsevier, 2014)
    The Wnt canonical ligands elicit the activation of β-catenin transcriptional activity, a response dependent on, but not limited to, β-catenin stabilization through the inhibition of GSK3 activity. Two mechanisms have been ...
  • Upon Wnt stimulation, Rac1 activation requires Rac1 and Vav2 binding to p120-catenin
    Valls, Gabriela; Codina, Montserrat; Miller, Rachel K.; Valle Pérez, Beatriz del; Vinyoles, Meritxell; Caelles Franch, Carme; McCrea, Pierre D.; García de Herreros, Antonio; Duñach, Mireia (Company of Biologists, 2012)
    A role for Rac1 GTPase in canonical Wnt signaling has recently been demonstrated, showing that it is required for β-catenin translocation to the nucleus. In this study, we investigated the mechanism of Rac1 stimulation by ...
