CET1/YPL228W Summary Help

Standard Name CET1 1
Systematic Name YPL228W
Alias CES5 2
Feature Type ORF, Verified
Description RNA 5'-triphosphatase; beta subunit of the mRNA capping enzyme, a heterodimer (the other subunit is CEG1, a guanylyltransferase) involved in adding the 5' cap to mRNA; the mammalian enzyme is a single bifunctional polypeptide; CET1 has a paralog, CTL1, that arose from the whole genome duplication (1, 3, 4, 5, 6)
Name Description Capping Enzyme Triphosphatase 1
