Methionyl aminopeptidase type 1D (mitochondrial); 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). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed (By similarity). May play a role in colon tumorigenesis; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
Synonyms: METAP1D, METAP1Dp, hMETAP1D, Q6UB28, MAP1D ...
