  1. Feature types found to be significantly (Fisher’s Exact test, E-value < 0.05) over-/under-represented in the unstable protein class when compared to stable and non-assigned proteins. E-values for over-represented features are indicated with the symbol ‡, otherwise the E-value represents an under-representation. Features include domain/architecture types, PTMs, and disorder classifications based on three disorder types (loops/coils, hotloops and rem465) and percentage of sequence containing the disorder type. Lastly, the presence of a destabilizing N-terminal residue is shown, defined as the N-terminal residue of a mature protein being one of R, K, H, F, L, W, I or Y. These results are from the full data set (without removal of transmembrane or secreted proteins).
