Abstract

Abstract

En 中文
• Y654F mutation inhibits phosphorylation of tension-gated β-catenin in hESCs • Mutation prevents BMP4-driven EMT and mesoderm signaling • Mutation prevents junctional to nuclear β-catenin translocation and Wnt secretion • Mesoderm signaling is rescued in mutant with Wnt3a addition or GSK3β inhibition
