We probe the unification of down quarks and leptons in a supersymmetric SO(10) GUT. The large atmospheric neutrino mixing angle induces b{sub R}-s{sub R} transitions, which can account for the sizeable CP phase oe{sub s} measured in B{sub s}-B{sub s} mixing. Corrections to down-quark-lepton unification from higher-dimensional Yukawa terms translate neutrino mixing also into s{sub R}-d{sub R} and b{sub R}-d{sub R} currents. We find the flavour structure of Yukawa corrections to be strongly constrained by epsilon{sub K}.
