The COMPASS-like family of lysine methyltransferases, MLR/MLX complexes, are epigenetic regulators that are essential for normal development through the methylation of the fourth lysine residue on histone 3 (H3K4), a universal epigenetic mark associated with active transcription. This family of complexes is highly conserved from yeast to mammals and the genes encoding the human MLR complexes have been associated with various developmental diseases and cancers (Dingwall and Fagan, 2019). In D. melanogaster, the enzymatic methyltransferase core of this complex is composed of two proteins: Cara Mitad (Cmi, also known as Lpt) and Trithorax-related (Trr). Although these proteins have been shown …

Mixed Lineage Leukemia protein (MLL) is required for proper embryonic development, and hematopoiesis. It is a SET domain containing histone methyl transferase that trimethylates histone H3 on lysine 4 (H3K4Me3), a histone modification that correlates with active transcription. The 3rd PHD finger of MLL binds to H3K4me3. Thus MLL is a "writer" with an embedded "reader" for H3K4Me3. Cyp33 is another known ligand of MLL PHD3. Over expression of Cyp33 results in transcriptional repression of MLL target genes.
The aim of this study is to determine the biological function of MLL PHD3 binding to H3K4Me3 or Cyp33. Cyp33 binding to …
