Zebrafish lypd6 Is a Wnt/β-Catenin Target Gene that Codes for a GPI-Anchored Plasma Membrane Protein

(A) lypd6 whole-mount in situ hybridization (WMISH) showing downregulation in transgenic embryos expressing Axin1 or Dkk1 at gastrula and somitogenesis stages (n [85% epiboly]: Axin1 16/17 embryos, Dkk1 19/19; n [10-somites]: Axin1 21/21, Dkk1 18/18). hs, heat shock.

(B) lypd6 expression levels determined by qRT-PCR in hs:Axin1, hs:Dkk1, and hs:Wnt8 transgenic embryos treated as in (A) and shown relative to those in wild-type embryos. Error bars, SEM.

(C) Domain structure of N-terminally GFP-tagged wild-type (spGFP-Lypd6) and C-terminally truncated Lypd6 (spGFP-Lypd6ΔGPI).

(D) Localization of spGFP-Lypd6 and spGFP-Lypd6ΔGPI in enveloping layer (EVL) cells of dome stage zebrafish embryos and in Chinese hamster ovary (CHO) cells.

(E) Release of spGFP-Lypd6 and spGFP-GPI from the plasma membrane of HEK293T cells upon treatment with phosphatidylinositol-specific phospholipase C (PiplC). spGFP-Lypd6ΔGPI and spGFP are detectable in the conditioned media without PiplC treatment.
