An interaction study of the SLC2A4 gene, predicted by ProteomicsDB [70], shows its relationship with pathways such as T2DM, FoxO signaling, adipocytokine signaling, insulin signaling, and AMPK signaling, as well as interactions with the protein coding genes SNAP23, HDAC3, RHOQ, NCOR1, and STXBP3. The interacting pathways for these protein–protein interactions with GLUT4 were assessed by automatic mapping of identifiers using STRING [71] and the functional pathways were determined by KEGG [72] as shown in Figure 2. The gene discussed is SLC2A4; the disease is type 2 diabetes mellitus.
