Aberrant PCM1 accumulation in Trisomy 21 mislocalizes E3 ligases, delaying primary ciliogenesis
Primary cilia are microtubule-based extracellular signaling structures essential for development and tissue homeostasis, and their defects can cause ciliopathies. Trisomy 21, the cause of Down syndrome, also disrupts cilia formation and function. Here we show that Pericentrin (PCNT), a chromosome 21 resident gene whose protein is elevated in Trisomy 21, impairs primary ciliogenesis by delaying…
