TMEM52B and nasopharyngeal carcinoma: We substantiated that the plasma membrane association of TMEM52B‐P20 distinguishes its role in NPC metastasis from TMEM52B‐P18, by generating TMEM52B‐P20 mutants deficient in membrane localization; unlike wild‐type TMEM52B‐P20, these mutants were not more effective than TMEM52B‐P18 in promoting the migration and invasion of HONE‐1 cells.
