Methylphosphate Capping Enzyme (MEPCE) ELISA Kit for Mouse

BCDIN3: a CDK9-associated enzyme that forms the distinctive gamma-methylphosphate cap structure of 7SK, a noncoding RNA that regulates CDK9 activity. An adenosyl-L-methionine-dependent methyltransferase that adds a methylphosphate cap at the 5'-end of 7SK snRNA, leading to its stabilization. Component of the 7SK snRNP complex that contains P-TEFb (composed of CDK9 and CCNT1), HEXIM1, HEXIM2, BCDIN3, SART3 proteins and 7SK and U6 snRNAs. Expressed in chronic myeloid leukemia cells, adrenal gland, brain, cerebellum, kidney, lung, mammary gland and testis. Weakly or not expressed in other tissues. Contains a Bin3 domain found in a number of protein methyltransferases that modify RNA-binding proteins.
