ITGA2B and type 2 diabetes mellitus: LC-MS/MS analysis of GPIIb/IIIa isolated from T2DM patients and control subjects was performed to identify the glycation sites of this integrin In both groups, integrin was glycated; however, the number of glycated lysines identified was higher in T2DM patients (residues K119 in subunit GPIIb and K669, K676, K764, K774 in subunit GPIIIa in control vs. K119, K532, K1025 in subunit GPIIb and K72, K436, K545, K645, K669, K676, K672, K764, K774 in subunit GPIIIa for T2DM) (Figure 4).
