Abstract
The emergence of the basement membrane (BM), a specialized form of extracellular matrix, was essential in the unicellular transition to multicellularity. However, the mechanism is unknown. Goodpasture antigen-binding protein (GPBP), a BM protein, was uniquely poised to play diverse roles in this transition owing to its multiple isoforms (GPBP-1, -2, and -3) with varied intracellular and extracellular functions (ceramide trafficker and protein kinase). We sought to determine the evolutionary origin of GPBP isoforms. Our findings reveal the presence of GPBP in unicellular protists, with GPBP-2 as the most ancient isoform. In vertebrates, GPBP-1 assumed extracellular function that is further enhanced by membrane-bound GPBP-3 in mammalians, whereas GPBP-2 retained intracellular function. Moreover, GPBP-2 possesses a dual intracellular/extracellular function in cnidarians, an early nonbilaterian group. We conclude that GPBP functioning both inside and outside the cell was of fundamental importance for the evolutionary transition to animal multicellularity and tissue evolution.

Abstract
Diabetes is characterized, in part, by activation of toxic oxidative and glycoxidative pathways that are triggered by persistent hyperglycemia and contribute to diabetic complications. Inhibition of these pathways may benefit diabetic patients by delaying the onset of complications. One such inhibitor, pyridoxamine (PM), had shown promise in clinical trials. However, the mechanism of PM action in vivo is not well understood. We have previously reported that hypohalous acids can cause disruption of the structure and function of renal collagen IV in experimental diabetes (K.L. Brown et al., Diabetes 64:2242-2253, 2015). In the present study, we demonstrate that PM can protect protein functionality from hypochlorous and hypobromous acid-derived damage via a rapid direct reaction with and detoxification of these hypohalous acids. We further demonstrate that PM treatment can ameliorate specific hypohalous acid-derived structural and functional damage to the renal collagen IV network in a diabetic animal model. These findings suggest a new mechanism of PM action in diabetes, namely sequestration of hypohalous acids, which may contribute to known therapeutic effects of PM in human diabetic nephropathy.

Abstract
In diabetes, toxic oxidative pathways are triggered by persistent hyperglycemia and contribute to diabetes complications. A major proposed pathogenic mechanism is the accumulation of protein modifications that are called advanced glycation end products. However, other nonenzymatic post-translational modifications may also contribute to pathogenic protein damage in diabetes. We demonstrate that hypohalous acid-derived modifications of renal tissues and extracellular matrix (ECM) proteins are significantly elevated in experimental diabetic nephropathy. Moreover, diabetic renal ECM shows diminished binding of α1β1 integrin consistent with the modification of collagen IV by hypochlorous (HOCl) and hypobromous acids. Noncollagenous (NC1) hexamers, key connection modules of collagen IV networks, are modified via oxidation and chlorination of tryptophan and bromination of tyrosine residues. Chlorotryptophan, a relatively minor modification, has not been previously found in proteins. In the NC1 hexamers isolated from diabetic kidneys, levels of HOCl-derived oxidized and chlorinated tryptophan residues W(28) and W(192) are significantly elevated compared with nondiabetic controls. Molecular dynamics simulations predicted a more relaxed NC1 hexamer tertiary structure and diminished assembly competence in diabetes; this was confirmed using limited proteolysis and denaturation/refolding. Our results suggest that hypohalous acid-derived modifications of renal ECM, and specifically collagen IV networks, contribute to functional protein damage in diabetes.
