Protein virilizer homolog (VIRMA)

Associated component of the WMM complex, a complex that mediates N6-methyladenosine (m6A) methylation of RNAs, a modification which plays a role in the efficiency of mRNA splicing and RNA processing (PubMed:24981863, PubMed:29507755). Acts as a key regulator of m6A methylation by encouraging m6A methylation of mRNAs in the 3'-UTR close to the stop codon: recruits the catalytic core elements METTL3 and METTL14, thereby directing m6A methylation at specific sites (PubMed:29507755).

Required for mRNA polyadenylation through its role in selective m6A methylation: m6A methylation of mRNAs in the 3'-UTR close to the stop codon correlating with other polyadenylation (APA) (PubMed:29507755). .
