Anti-METTL1

Protein function: Methyltransferase that mediates the formation of N(7)- methylguanine in a subset of RNA species, such as tRNAs, mRNAs and microRNAs (miRNAs) (PubMed:12403464, PubMed:31031084, PubMed:31031083). Catalyzes the formation of N(7)-methylguanine at position 46 (m7G46) in tRNA (PubMed:12403464, PubMed:31031084). Also acts as a methyltransferase for a subset of internal N(7)-methylguanine in mRNAs (PubMed:31031084). Internal N(7)-methylguanine methylation of mRNAs regulates translation (PubMed:31031084). Also methylates a specific subset of miRNAs, such as let-7 (PubMed:31031083). N(7)-methylguanine methylation of let-7 miRNA promotes let-7 miRNA processing by disrupting an inhibitory secondary structure within the primary miRNA transcript (pri-miRNA) (PubMed:31031083). Acts as a regulator of embryonic stem cell self-renewal and differentiation. [The UniProt Consortium] Buffer: 40% glycerol and PBS (pH 7.2). 0.02% sodium azide is added as preservative.
