lypd6 Acts in Wnt-Receiving Cells at the Level of the Wnt Receptor Complex (A) pBAR luciferase reporter activity in mouse L cells treated with CM produced from control or Wnt3a-producing L cells that were transfected with lypd6 or control siRNA. Error bars, SEM. (B) pBAR luciferase reporter activity in Wnt3a CM treated L cells transfected with lypd6 siRNA. Error bars, SEM. (C) lypd6 enhances Wnt/β-catenin signaling upstream of the β-catenin degradation complex. Coinjection of lypd6 RNA rescues the reduction in reporter activity in 7xTcf:mCherry embryos caused by wnt8 MOs (5 ng each, 17/22), but not by RNAs of axin1 (50 pg, 19/19), gsk3β (150 pg, 17/20), or dominant negative tcf3, tcf3ΔC (125 pg, 23/24) at the 85% epiboly stage.
