Reasoning on structural clustering and protein function in Ras GTPases

InferenceChain·arcadia

Explains why proteins clustered by ProteinCartography may function similarly: clusters are primarily composed of a single Ras subfamily, share similar folds as measured by TM-score, and typically share key sequence/structural features underlying functional similarity. Differences in annotation quality, taxonomic distribution, and structural compactness between clusters support the hypothesis that proteins in different clusters have different functions.
