DEGRONOPEDIA is a web server that combines experimental data on degron motifs with their multilayer context annotation. It allows the study of peptide motifs that can act as a primary degron in a tripartite degron architecture. In this model, the secondary degron refers to a lysine to which ubiquitin can be attached, while the tertiary degron points to a flexible, internally disordered region close to the secondary degron, acting as an initiating site for proteasomal degradation.

DEGRONOPEDIA annotates not only lysine as a potential ubiquitination site but also cysteine/threonine/serine, as ubiquitin can be attached to these. The server also provides information on post-translational modifications and pathogenic mutations within the degron and its flanking regions, as these can modulate degron accessibility. Since degrons can be formed after cleavage by proteases, we simulate sequence pruning based on user-defined sites, experimental data and theoretical predictions and search for emerging new degrons. Furthermore, DEGRONOPEDIA allows you to analyze your own sequence/structure to examine it for degrons and use machine learning to predict its N-/C-terminal stability.
