AP-2β can target multiple features of obesity and T2D centrally and peripherally by modulating key-obesity linked genes such as IRS-1, GLUT4, adipocytokines related genes, as well as catecholaminergic and serotonergic genes involved in reward, consummatory behaviour and insulin resistance (Table 3). Here, SLC2A4 is linked to obesity due to melanocortin 4 receptor deficiency.
