BDP1 and cancer: After rabbit-anti M6PR was added to the immunoprecipitate of Gimap5, the mass spectrometry results indicated that M6RP interacted with protein-arginine deiminase type-4 (PADI4), actin, cytoplasmic 2 (ACTG1), Keratin, type II cytoskeletal 6A (KRT6A), breast cancer anti-estrogen resistance protein 1 (BCAR1), and transcription factor TFIIIB component B homolog (BDP1) (Figure 5F).
