To investigate whether N-CoR misfolding in AML-M5 was also caused by aberrant serine/threonine phosphorylation, N-CoR immunoprecipitated (IP) from the whole cell extracts of AEBSF or genistein treated THP-1 cells was probed with a generic pan-phospho serine/threonine antibody. The gene discussed is NCOR1; the disease is acute myeloid leukemia.
