The REF values for such proteins as ERLIN2 (ER membrane lipid raft-associated 2), FANCI (Fanconi anemia complementation group I) and BAG2 (BAG family molecular chaperone regulator 2) were 0.72, 0.72 and 0.3 in only AIMP2 immunoprecipitates unlike those of AIMP1 and KARS (Table S3). This evidence concerns the gene FANCI and Fanconi anemia.
