Table 1.

The number of proteins in the training, validation and test sets for the PPI and PPI_extendedSFD datasets.

Structural information	PPI dataset		PPI_extendedSFD
Structural information	SF + PPI	Only SF	SF + PPI	Only SF
Training set	2842	0	2842	5961
Validation set	353	0	353	749
Test set	356	0	356	746

The PPI dataset only contains proteins for which both structural features and PPI interface annotations are available. The PPI_extendedSFD dataset contains additional proteins for which only structural features are available.
