Function

METL9_HUMAN Protein-histidine N-methyltransferase that specifically catalyzes 1-methylhistidine (pros-methylhistidine) methylation of target proteins (PubMed:33563959, PubMed:34562450, PubMed:37015930, PubMed:37398635). Specifically methylates the second His of proteins with a His-x-His (HxH) motif (where 'x' is preferably a small amino acid), while exploiting the first one as a recognition signature (PubMed:37398635). Catalyzes methylation of target proteins such as S100A9, NDUFB3, SLC39A5, SLC39A7, ARMC6 and DNAJB12; 1-methylhistidine modification may affect the binding of zinc and other metals to its target proteins (PubMed:33563959, PubMed:34562450, PubMed:37015930, PubMed:37398635). Constitutes the main methyltransferase for the 1-methylhistidine modification in cell (PubMed:33563959).^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Protein histidine N1-methylation (1-methylhistidine, 1-MH) is a prevalent yet underexplored post-translational modification in mammals. The methyltransferase METTL9 acts as an important enzyme catalyzing 1-MH of histidine in diverse protein substrates, with mounting evidence suggesting its involvement in tumor progression. Despite its potential significance, no inhibitors targeting METTL9 have been previously identified. Here, we introduce compound METTL9i as a first-in-class, highly potent, and selective METTL9 inhibitor. METTL9i inhibits METTL9 with a half-maximum inhibitory concentration (IC(50)) of 0.067 +/- 0.009 microM and exhibits selectivity over other methyltransferases. Structural analysis via crystallography reveals that METTL9i binds within the S-adenosylmethionine (SAM) binding pocket. In cells, METTL9i engages METTL9 and leads to a reduction in global 1-MH levels. These results support METTL9i as a useful tool compound for investigating METTL9 biology and the functions of histidine 1-MH, while also serving as a promising lead compound for drug discovery targeting METTL9.
