Table I. IDO2 interacting proteins.

Full-length cDNA for mouse IDO2 was cloned as a C-terminal fusion to LexA. The construct was screened against a mouse spleen cDNA library using a mating approach with YHGX13 and L40ΔGal4 yeast strains. His⁺ colonies were selected on a medium lacking tryptophan, leucine, and histidine. Predicted biological score (PBS): A: Very high confidence interaction; B: High confidence interaction; C: Good confidence interaction; D: Moderate confidence interaction.

PBS	Prey Protein
B	Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)
D	Runt related transcription factor 1 (Runx1)
D	Meningioma expressed antigen 5 (Mgea5)
B	RAN binding protein 10 (Ranbp10)
