COPB2 and cancer: Several signaling pathways—especially inflammation‐ and immunity‐related pathways—were enriched in the COPB2 high expression phenotype, including B‐cell receptor, T‐cell receptor, natural killer (NK) cell‐mediated cytotoxicity, antigen processing and presentation, Fc gamma R‐mediated phagocytosis, cytokine‐cytokine receptor interaction, leukocyte transendothelial migration, and other pathways in cancer (please see Figure 3 and Table 4).
