AB - Shisa is an antagonist of Wnt and FGF signaling, that functions cell autonomously in the endoplasmic reticulum (ER) to inhibit the post-translational maturation of Wnt and FGF receptors. In this paper we report the isolation of a second Xenopus shisa gene (Xshisa-2). Xenopus Shisa-2 shows 30.7% identity to Xshisa. RT-PCR analysis indicated that Xshisa-2 mRNA is present throughout early development and shows an increased expression during neurula and tailbud stages. At neurula stages Xenopus shisa-2 is initially expressed in the presomitic paraxial mesoderm and later in the developing somites. The expression profiles and pattern of Xshisa and Xshisa-2 differ significantly. During gastrulation only Xshisa mRNA is present in the Spemann-Mangold organizer and later on becomes restricted to the neuroectoderm and the prechordal plate.
