Next, to identify the kinase involved in N-CoR phosphorylation, we screened a human phospho-kinase antibody array (Proteome ProfilerTM) with the extracts of five AML-M5 (THP-1, Nomo-1, MM1, MV-4–11 and SigM5) and three non-AML-M5 (U937, HL-60 and K562) derived cell lines. This evidence concerns the gene NCOR1 and acute myeloid leukemia.
