Function
[MCES_HUMAN] mRNA-capping methyltransferase that methylates the N7 position of the added guanosine to the 5'-cap structure of mRNAs. Binds RNA containing 5'-terminal GpppC.[1] [2] [3] [4] [RAM_HUMAN] Required for efficient mRNA cap methylation. Regulates RNMT expression by a post-transcriptional stabilizing mechanism.[5]
