Distinct roles of centriole distal appendage proteins in ciliary assembly and disassembly.

The primary cilium is a cellular organelle whose assembly and disassembly are closely linked to the cell cycle. The centriole distal appendage (DA) is essential for the early stages of ciliogenesis by anchoring the mother centriole to the cell surface. Despite the identification of over twelve proteins constituting the DA, including CEP83, CEP89, CEP164, FBF1, and SCLT1, their specific functions in ciliary dynamics are not fully understood.

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

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.
