  "summary": "TMEM165 is a Golgi-resident multi-pass membrane protein involved in divalent cation homeostasis and associated with congenital disorders of glycosylation, yet its N-terminal biogenesis has remained unresolved. Here, we demonstrate that TMEM165 contains a functional cleavable signal peptide required for correct Golgi targeting and membrane topology. Loss of this signal peptide causes protein…",
