TMEM132A regulates Wnt/β-catenin signaling through stabilizing LRP6 during mouse embryonic development.

ABSTRACT: The Wnt/β-catenin signaling pathway is crucial for embryonic development and adult tissue homeostasis. Dysregulation of Wnt signaling is linked to various developmental anomalies and diseases, notably cancer. Although numerous regulators of the Wnt signaling pathway have been identified, their precise function during mouse embryo development remains unclear. Here, we revealed that TMEM132A is a crucial regulator of canonical Wnt/β-catenin signaling in mouse development. Mouse embryos lacking Tmem132a displayed a range of malformations, including open spina bifida, caudal truncation, syndactyly, and renal defects, similar to the phenotypes of Wnt/β-catenin mutants. Tmem132a knockdown in cultured cells suppressed canonical Wnt/β-catenin signaling. In developing mice, loss of Tmem132a also le
