Description
Product Characteristics: O-methyltransferase that specifically monomethylates 5'-monophosphate of cytoplasmic histidyl tRNA (tRNA(His, acting as a capping enzyme by protecting tRNA(His from cleavage by DICER1. Also able, with less efficiently, to methylate the 5' monophosphate of a subset of pre-miRNAs, acting as a negative regulator of miRNA processing. The 5' monophosphate of pre-miRNAs is recognized by DICER1 and is required for pre-miRNAs processing: methylation at this position reduces the processing of pre-miRNAs by DICER1. Was also reported to mediate dimethylation of pre-miR-145, however dimethylation cannot be reproduced by another group which observes a monomethylation of pre-miR-145.,AV138748, 4930556P03Rik,Bcdin3d
Target Information: Probable methyltransferase (By similarity)
