Enzyme type: methyltransferase
Position of modification - modification: m:many - m6A


Ime4 catalyses the AdoMet-dependent N6-methylation of internal adenosine in yeast mRNA, including mRNA coding for Ime4 (regulatory role). Like the MT-A70 human homolog, Sce-Ime4 works within a multiprotein complex and requires additional subunits, e.g. Kar4p, GI140396. While Mum2 and Slz1 interact and co-immunoprecipitate with Ime4, including mRNA coding for Ime4. The methyl group of m6A in mRNA can be removed by FTO/AlkB-like demethylase enzyme.
