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[1]. 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)[2]. WD repeat-containing protein 48 and 20 act as regulators of deubiquinating complexes. WD repeat-containing protein 41 is the non-catalytic component of C9orf72-SMCR8 complex which regulates autophagy[3]. Disease Mutant WDR is involved in triple-A syndrome[4]. Structural highlights The of the WDR5 β-propellor structure acting like an anchoring pin [5]. Water molecules are shown as red spheres. 3D Structures of WD-repeat protein WD-repeat protein 3D structures
