MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the cytosolic form of a metalloaminopeptidase that catalyzes the cleavage of the N-terminal amino acid adjacent to a proline residue. The gene product may play a role in degradation and maturation of tachykinins, neuropeptides, and peptide hormones. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Nov 2009]
PHENOTYPE: Mice homozygous for a gene trap allele exhibit pre and postnatal lethality, reduced male survival, growth retardation with decreased body weight, size and length, microcephaly and peptiduria. [provided by MGI curators]
