The thyroid adenoma associated gene (THADA) maintains the residency of cPD‐L1 in the Golgi, thus promoting its maturation and facilitating intracellular transport.[105] Mechanistically, THADA fastens cPD‐L1 to COPII vesicles by Sec24A‐mediated anchoring, thereby enabling cPD‐L1 transport from ER to the Golgi and stabilizing its Golgi residency. The gene discussed is THADA; the disease is Thyroid adenoma.
