background:
The N-terminal methionine excision pathway is an essential process in which the N-terminal methionine is removed from many proteins, thus facilitating subsequent protein modification. In mitochondria, enzymes that catalyze this reaction are celled methionine aminopeptidases (MetAps, or MAPs; EC 3.4.11.18) (Serero et al., 2003 [PubMed 14532271]).[supplied by OMIM, Mar 2008]
Function:
Removes the amino-terminal methionine from nascent proteins (By similarity). May play a role in colon tumorigenesis.
Subcellular Location:
Mitochondrion.
Tissue Specificity:
Overexpressed in colon cancer cell lines and colon tumors as compared to normal tissues (at protein level).
Similarity:
Belongs to the peptidase M24A family.
