Antigen: phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser^33,37 of human β-catenin · Host: rabbit · Application(s): WB · β-Catenin is a central component of the cadherin cell adhesion complex and plays an essential role in neural development in the Wingless/Wnt signaling pathway.^1,2 The role of β-catenin in these processes is thought to be regulated by the sequential phosphorylation of Ser²⁹, Ser³³, Ser³⁷, and Thr⁴¹ by glycogen synthase kinase 3β (GSK3β).³ This hyperphosphorylation promotes the ubiquitylation and targeted destruction of β-catenin. Mutations in components of this phosphorylation-regulated process that prevent β-catenin hyperphosphorylation by GSK3β are strongly associated with cancers.^3,2,4
