METAP1 Cotranslationally removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Required for normal progression through the cell cycle. Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily. Note: This description may include information from UniProtKB.
