COPB2 and malignant colon neoplasm: Figure 4(a) indicates three COPB2 phosphorylation sites. The S859 and T861 sites indicated higher phosphorylation levels in OV and breast cancer tissues compared with those noted in normal tissues, while the opposite results were obtained in colon cancer samples (Figures 4(b)–4(d)). In addition, the T828 locus was also expressed at significantly increased levels in UCEC (Figure 4(e)).
