Anti-METTL1 antibody [EPR24320-27],Abcam,AB271063

Target data Catalytic component of METTL1-WDR4 methyltransferase complex that mediates the formation of N(7)-methylguanine in a subset of RNA species, such as tRNAs, mRNAs and microRNAs (miRNAs) (PubMed : 12403464, PubMed : 31031083, PubMed : 31031084, PubMed : 36599982, PubMed : 36599985, PubMed : 37369656, PubMed : 37379838). Catalyzes the formation of N(7)-methylguanine at position 46 (m7G46) in a large subset of tRNAs that contain the 5'-RAGGU-3' motif within the variable loop (PubMed : 12403464, PubMed : 34352206, PubMed : 34352207, PubMed : 36599982, PubMed : 36599985, PubMed : 37369656). M7G46 interacts with C13-G22 in the D-loop to stabilize tRNA tertiary structure and protect tRNAs from decay (PubMed : 36599982, PubMed : 36599985). Also acts as a methyltransferase for a subset of internal N(7)-methylguanine in mRNAs (PubMed : 31031084, PubMed : 37379838). Internal N(7)-methylguanine methylation of mRNAs in response to stress promotes their relocalization to stress granules, thereby suppressing their translation (PubMed : 31031084, PubMed : 37379838). 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 (By similarity). See full target information METTL1
