== Function ==
 +
[https://www.uniprot.org/uniprot/MAP2_HUMAN MAP2_HUMAN] 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). The catalytic activity of human METAP2 toward Met-Val peptides is consistently two orders of magnitude higher than that of METAP1, suggesting that it is responsible for processing proteins containing N-terminal Met-Val and Met-Thr sequences in vivo. Protects eukaryotic initiation factor EIF2S1 from translation-inhibiting phosphorylation by inhibitory kinases such as EIF2AK2/PKR and EIF2AK1/HCR. Plays a critical role in the regulation of protein synthesis.

== Publication Abstract from PubMed ==
 +
Human methionine aminopeptidase type 2 (hMetAP-2) was identified as the molecular target of anti-angiogenic agents such as fumagillin and its analogues. We describe here the crystal structure of hMetAP-2 in complex with l-methionine and d-methionine at 1.9 and 2.0A resolution, respectively. The comparison of the structure of the two complexes establishes the basis of enantiomer discrimination and provides some considerations for the design of selective MetAP-2 inhibitors.
