General Comments
WDR5 is involved in the formation of heterotrimeric or multiprotein complexes eg the histone acetyltransferase complex and the histone methyltransferase complex [6-7]. It is a chromatin-associated protein that is an essential recruiting factor for the MYC oncoprotein (transcription factor) to MYC-regulated genes. WDR5 is a validated molecular target for oncology drug discovery, whose inhibition is predicted to offer therapeutic benefit in solid and haematological malignancies that are driven by oncogenic MYC activity.
