 In our experience, degrons that are similar to each other will tend to overlap with each other in which query sequences from the database are scored favorably. Thus, the output from DegronID can be harnessed to cluster degron motifs into related groups. Illustration of the clustering result from Zhang et al. and related visualizations are accessible at https://brandonsie.shinyapps.io/DegronID/.

 ## Other Applications 
 
-Although we used this method to characterize saturation mutagenesis of degrons, this algorithm could conceivably be applied to various other applications involving saturation mutagenesis, such as for investigation of cross reactivity between TCR epitopes.
