Consistent with the mRNA data, lung squamous ecll carcinoma and HNSCC tumors exhibited high expression of ULBP6/2/5, with variable patterns of membranous and nonmembranous ULBP6/2/5 indicative of a differential degree of ULBP6/2/5 shedding (Fig. 2C). Here, RAET1L is linked to head and neck squamous cell carcinoma.
