We performed our IP and mass spectrometry experiments similarly to Takao et al., where they IP’ed MYB to identify 724 unique proteins associated with MYB in nuclear extracts of MV411 AML cells.37 After immunoprecipitating with an antibody to NDUFA4L2 in RCC4-P and RCC4-KO-643 cells, we performed mass spectrometry on these IP’ed samples. Here, SLC49A4 is linked to acute myeloid leukemia.
