Target Information
S-adenosyl-L-methionine-dependent methyltransferase that adds a methylphosphate cap at the 5'-end of 7SK snRNA (7SK RNA), stabilizing it (PubMed:17643375, PubMed:19906723, PubMed:30559425).
Also has a non-enzymatic function as part of the 7SK RNP complex, which sequesters the positive transcription elongation factor b (P-TEFb) in an inactive complex, preventing RNA polymerase II phosphorylation and transcriptional elongation (PubMed:17643375).
The 7SK RNP complex also promotes snRNA gene transcription by RNA polymerase II via interaction with the little elongation complex (LEC) (PubMed:28254838).
In the 7SK RNP complex, MEPCE stabilizes 7SK RNA and facilitates complex assembly (PubMed:19906723).
Interaction with LARP7 within the 7SK RNP complex occludes its catalytic center (PubMed:19906723).
