An article in the December 24, 2009 issue of Molecular Cell,A Reconfigured Pattern of MLL Occupancy within Mitotic Chromatin Promotes Rapid Transcriptional Reactivation Following Mitotic Exit,” had me thinking how misleading genes and proteins are often named. The publication details the function of a protein, Mixed Leukemia Lineage (MLL), which attaches to DNA prior to cell division. MLL “bookmarks” genes that need to be expressed immediately after the cell divides. The protein’s function is not, however, to cause leukemia.
