Supplementary information

METTL1 also known as Methyltransferase-Like 1 is an enzyme responsible for catalyzing the methylation of specific substrates. This protein has a molecular mass of approximately 50 kDa. METTL1 is expressed across various tissues but shows higher expression levels in the brain and testes. Its enzymatic activity involves transferring a methyl group through its interaction with S-adenosylmethionine (SAM) to form N7-methylguanosine (m7G) on tRNA molecules which is essential for regulating their stability and function.
Biological function summary

METTL1 is important in modulating the processes of cellular growth and differentiation. METTL1 forms a complex with WDR4 which assists its function in tRNA modification. This complex is necessary for the precise modification of tRNA ensuring accurate protein synthesis and cellular homeostasis. Investigations reveal METTL1's role in cellular processes such as proliferation and stem cell maintenance highlighting its functional importance in cell cycle control and organismal development.

Pathways

METTL1 integrates into significant molecular pathways like mRNA translation and tRNA processing. METTL1 associates with proteins like SAM and FTO within these pathways. The enzyme influences the mTOR signaling pathway which plays a major role in regulating cellular growth and metabolism. Through its methyltransferase activity METTL1 impacts the proper functioning of ribosomes and protein synthesis linking it to the translational control of gene expression.

Research links METTL1 to various cancers including glioblastoma and lung cancer. Aberrant METTL1 expression or activity correlates with tumor progression and malignancy due to its role in altered protein synthesis. METTL1 dysregulation also relates to intellectual disabilities highlighting its importance in brain function. In the context of cancer proteins like mTOR and MYC have been connected to METTL1 by affecting pathways which influence tumor cell survival and proliferation.

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).
