WD repeats are ca. 40 amino acid long usually bordered by Gly-His and Trp-Asp (WD). All WDRs form a β-propeller structure. WDRs have critical roles in many biological functions like signal transduction, transcription regulation and apoptosis. WD-repeat protein 5 (WDR5) contains 7 WD repeats. WDR5 contributes to histone modification. It may position the N-terminal of histone H3 for efficient methylation at Lys4. This methylation is implicated in the control of activation of cell lineage genes during embryogenesis. WDR5 interacts with histone-lysine N-methyltransferase (MLL). WD repeat-containing protein 48 and 20 act as regulators of deubiquinating complexes. Disease Mutant WDR is involved in triple-A syndrome. Structural highlights The histone Arg2 residue inserts into the central pore of the WDR5 β-propellor structure acting like an anchoring pin forming numerous hydrogen bonds and cation-π interactions.
