KinAce: a web portal for exploring kinase-substrate interactions

Abstract

Interactions between protein kinases and their substrates are critical for the modulation of complex signaling pathways. Currently, there is a large amount of information available about kinases and their substrates in disparate public databases. However, these data are difficult to interpret in the context of cellular systems, which can be facilitated by examining interactions among multiple proteins at once, such as the network of interactions that constitute a signaling pathway. We present KinAce, a user-friendly web portal that integrates and shares information about kinase-substrate interactions from multiple databases of post-translational modifications. KinAce enables the visual exploration of these interactions in systems contexts, such as pathways, domain families, and custom protein set inputs, in an interactive fashion. We expect KinAce to be useful as a knowledge discovery tool for kinase-substrate interactions, and the aggregated KinAce dataset to be useful for protein kinase studies and systems-level analyses. The portal is available at https://kinace.kinametrix.com/.
