Target

  • Function

    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.
  • Sequence similarities

    Belongs to the peptidase M24A family. Methionine aminopeptidase eukaryotic type 2 subfamily.
  • Post-translational
    modifications

    Contains approximately 12 O-linked N-acetylglucosamine (GlcNAc) residues. O-glycosylation is required for EIF2S1 binding.
  • Cellular localization

    Cytoplasm. About 30% of expressed METAP2 associates with polysomes.

Images

  • Paraffin-embedded human testis tissue stained for Methionine Aminopeptidase 2/p67 using ab236755 at 1/100 dilution in immunohistochemical analysis.

    After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30 minutes at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

  • HepG2 (Human liver hepatocellular carcinoma cell line) cells stained for Methionine Aminopeptidase 2/p67 (green) using ab236755 at 1/100 dilution in ICC/IF. Secondary antibody is an Alexa-Fluor® 488-conjugated Goat Anti-Rabbit IgG (H+L). The nuclear counterstain is DAPI (blue).

    The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal goat serum. The cells were then incubated with the antibody overnight at 4°C.
