Mepce - methylphosphate capping enzyme

Predicted to enable 7SK snRNA binding activity and RNA 5'-methyltransferase activity. Predicted to be involved in RNA modification; positive regulation of protein localization to Cajal body; and positive regulation of snRNA transcription by RNA polymerase II. Predicted to act upstream of or within negative regulation of chromatin binding activity; negative regulation of transcription by RNA polymerase II; and positive regulation of G1/S transition of mitotic cell cycle. Predicted to be located in nucleus. Predicted to be part of 7SK snRNP. Orthologous to human MEPCE (methylphosphate capping enzyme). [provided by Alliance of Genome Resources, Apr 2022]
