DPEP3 and melanoma: These eight genes were dipeptidase 3 (DPEP3), enhancer of zest homologs inhibitory protein (EZHIP), three melanoma‐associated antigens (MAGEA4, MAGEB2, and MAGEC2), prostate‐associated antigen 1 (PAGE1), preferentially expressed antigen in melanoma (PRAME), and transketolase‐like 1 (TKTL1), corresponding to both highly characterized and poorly characterized proteins with regard to their function (Fig. S1).
