The STGC3 protein contains a glycosylation site, a protein kinase C (PKC) phosphorylation site, a casein kinase II phosphorylation site, three myristoylation sites and a laminin G domain.[8] It plays important roles in NPC cells.[9,10] The expression of STGC3 protein was down-regulated in NPC tissues and cell lines. Here, PRRT2 is linked to nasopharyngeal carcinoma.
