WDR5 Inhibitors

WD repeat domain 5 (WDR5) is a core component of the SET1 family of histone methyltransferases, specifically involved in the catalysis of histone H3 lysine 4 (H3K4) methylation, a key epigenetic mark associated with gene activation. WDR5 plays a critical role in various biological processes, including cell cycle regulation, development, and differentiation, by facilitating the assembly of the methyltransferase complex and mediating its interaction with histone substrates. Its interaction with other proteins is not limited to histone modifiers; WDR5 is also involved in the regulation of non-histone protein functions, thereby influencing numerous cellular pathways. The multifaceted roles of WDR5 underscore its importance in maintaining genomic stability and regulating gene expression, positioning it as a central player in epigenetic modulation and cellular function. The precise regulation of H3K4 methylation by WDR5 is crucial for the transcriptional activation of genes necessary for cellular growth and response to environmental stimuli, highlighting its significance in both normal physiology and disease states.

The inhibition of WDR5 involves disrupting its interaction with the SET1 family of methyltransferases or blocking its binding to histone or non-histone proteins. This can be achieved through small molecules or peptides that specifically target the WDR5 interaction domain, disrupting the formation of functional methyltransferase complexes and thereby reducing H3K4 methylation levels. Such inhibition directly impacts gene expression, leading to alterations in cellular pathways regulated by WDR5-mediated methylation. Inhibition strategies focus on the precise mechanisms by which WDR5 contributes to the assembly and function of methyltransferase complexes, aiming to modulate its activity without disrupting essential cellular functions.
