-In a few seconds or a few minutes, ARCTIC-3D will return a set of clusters representing possible binding surfaces with respect to protein functions. Take a look at the “ARCTIC3D clustering” plot - you’ll see that some amino acids are found in the interfaces of the multiple clusters, e.g. 93-V - clusters 2, 3 and 4, while some residues are found only in a single cluster e.g. 105-R - cluster 2.

+_**NOTE**_ this ARCTIC-3D run was performed in September 2025 and thus used strucutes available online at that time.
+With the time, new structures of MDM2_human may became available, which may lead to the change in the number and numbering of clusters.
+So if you're running ARCTIC-3D in the future, don't be surprised if the output looks a bit different!
