Nicotinamide adenine dinucleotide (NAD) is an essential metabolite in normal cellular physiology and its deregulation may lead to several pathological conditions. NAD interacts with a vast number of proteins, acting as a coenzyme, as a substrate and regulating the interaction between proteins. The goals of this study were to characterize the proteins involved in NAD metabolism and to identify putative new NAD regulated proteins. Using an in silico approach, we first defined a NAD-binding dataset, that we characterized through pathway enrichment analysis and protein structural domains analysis. We then screened the full human proteome and further analyzed a selection of potential NAD-binding proteins. This global study of the NAD interactome resulted in the identification of new potentially NAD-binding proteins (NADPBs), including TRPC3 and a few isoforms of DGA kinases, which are involved in calcium signaling. NADBPs participate in several metabolic pathways and signaling processes in the cell, while proteins interacting with NADPBs are mostly involved in signaling pathways, including pathways related to disease, namely three major neurodegenerative diseases, Alzheimer’s, Huntington’s, and Parkinson’s.
