We previously demonstrated that p15RS, a newly discovered tumor suppressor, inhibits Wnt/β-catenin signaling by interrupting the formation of β-catenin·TCF4 complex. However, it remains unclear how p15RS helps exert such an inhibitory effect on Wnt signaling based on its molecular structure. In this study, we reported that dimerization of p15RS is required for its inhibition on the transcription regulation of Wnt-targeted genes. We found that p15RS forms a dimer through a highly conserved… Expand
