Abstract

Accumulating evidence has revealed that the methylation of lysines on nonhistones by histone lysine methyltransferases (HMTs) is crucial for regulating tumo­rigenesis and metastasis. However, whether the methy­lation of lysines on HMT complex components occurs and has functions in cancer progression is less well understood. WD repeat domain 5 (WDR5) is a core component of an HMT complex named mixed lineage leukemia (MLL)/Suppressor of Variegation, Enhancer of Zeste, and Trithorax 1 (SET1). In the present study, it was reported that lysines 207 and 325 (K207 and K325, respectively) of WDR5 were monomethylated by SET‑domain‑containing protein methyltransferase 6. Disrupting the methylation of K207/K325 via a K207R/K325R double‑site mutation attenuated the WDR5 promotion of breast cancer cell proliferation and migration. Methylation of K207/K325 on WDR5 partially contributed to maintaining global histone tri‑methylation of lysine 4 on histone H3 levels, but did not affect MLL/SET1 complex assembly. These results further understanding of a potential post‑translational modification of WDR5, and imply that the methylation of lysines on HMT complex components is crucial for regulating human carcinogenesis.
