>gnl|CDD|189008 cd09601, M1_APN_2, Peptidase M1 Aminopeptidase N family incudes
tricorn interacting factor F3, Endoplasmic reticulum
aminopeptidase 1 (ERAP1), Aminopeptidase Q (APQ). This
M1 peptidase family includes eukaryotic and bacterial
members: aminopeptidase N (APN), aminopeptidase Q (APQ,
laeverin), endoplasmic reticulum aminopeptidase 1
(ERAP1) as well as tricorn interacting factor F3.
Aminopeptidase N (APN; CD13; Alanyl aminopeptidase; EC
3.4.11.2), a Type II integral membrane protease,
consists of a small N-terminal cytoplasmic domain, a
single transmembrane domain and a large extracellular
ectodomain that contains the active site. It
preferentially cleaves neutral amino acids from the
N-terminus of oligopeptides and is present in a variety
of human tissues and cell types (leukocyte, fibroblast,
endothelial and epithelial cells). APN expression is
dysregulated in inflammatory diseases such as chronic
pain, rheumatoid arthritis, multiple sclerosis, systemic
sclerosis, systemic lupus erythematosus,
polymyositis/dermatomyosytis and pulmonary sarcoidosis,
and is enhanced in tumor cells such as melanoma, renal,
prostate, pancreas, colon, gastric and thyroid cancers.
It is considered a marker of differentiation since it is
predominantly expressed on stem cells and on cells of
the granulocytic and monocytic lineages at distinct
stages of differentiation. Thus, APN inhibition may lead
to the development of anti-cancer and anti-inflammatory
drugs. ERAP1 also known as endoplasmic reticulum
aminopeptidase associated with antigen processing
(ERAAP), adipocyte derived leucine aminopeptidase
(A-LAP) or aminopeptidase regulating tumor necrosis
factor receptor I (THFRI) shedding (ARTS-1), associates
with the closely related ER aminopeptidase ERAP2, for
the final trimming of peptides within the ER for
presentation by MHC class I molecules. ERAP1 is
associated with ankylosing spondylitis (AS), an
inflammatory arthritis that predominantly affects the
spine. ERAP1 also aids in the shedding of membrane-bound
cytokine receptors. The tricorn interacting factor F3,
together with factors F1 and F2, degrades the tricorn
protease products, producing free amino acids, thus
completing the proteasomal degradation pathway. F3 is
homologous to F2, but not F1, and shows a strong
preference for glutamate in the P1' position. APQ, also
known as laeverin, is specifically expressed in human
embryo-derived extravillous trophoblasts (EVTs) that
invade the uterus during early placentation. It cleaves
the N-terminal amino acid of various peptides such as
angiotensin III, endokinin C, and kisspeptin-10, all
expressed in the placenta in large quantities. APN is a
receptor for coronaviruses, although the virus receptor
interaction site seems to be distinct from the enzymatic
site and aminopeptidase activity is not necessary for
viral infection. APNs are also putative Cry toxin
receptors. Cry1 proteins are pore-forming toxins that
bind to the midgut epithelial cell membrane of
susceptible insect larvae, causing extensive damage.
Several different toxins, including Cry1Aa, Cry1Ab,
Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to
bind to APNs; however, a direct role of APN in
cytotoxicity has been yet to be firmly established.

>gnl|CDD|189002 cd09595, M1, Peptidase M1 family contains aminopeptidase N and
leukotriene A4 hydrolase. M1 Peptidase family includes
aminopeptidase N (APN) and leukotriene A4 hydrolase
(LTA4H). All peptidases in this family bind a single
catalytic zinc ion which is tetrahedrally co-ordinated
by three amino acid ligands and a water molecule that
forms the nucleophile on activation during catalysis.
APN consists of a small N-terminal cytoplasmic domain, a
single transmembrane domain and a large extracellular
ectodomain that contains the active site. It
preferentially cleaves neutral amino acids from the
N-terminus of oligopeptides and is present in a variety
of human tissues and cell types. APN expression is
dysregulated in many inflammatory diseases and is
enhanced in numerous tumor cells, making it a lead
target in the development of anti-cancer and
anti-inflammatory drugs. LTA4H is a bifunctional enzyme,
possessing an aminopeptidase as well as an epoxide
hydrolase activity. The two activities occupy different,
but overlapping sites. The activity and physiological
relevance of the aminopeptidase in LTA4H is as yet
unknown while the epoxide hydrolase converts leukotriene
A4 (LTA4) into leukotriene B4 (LTB4), a potent
chemotaxin that is fundamental to the inflammatory
response of mammals.

>gnl|CDD|233858 TIGR02414, pepN_proteo, aminopeptidase N, Escherichia coli type.
The M1 family of zinc metallopeptidases contains a
number of distinct, well-separated clades of proteins
with aminopeptidase activity. Several are designated
aminopeptidase N, EC 3.4.11.2, after the Escherichia
coli enzyme, suggesting a similar activity profile (see
SP|P04825 for a description of catalytic activity). This
family consists of all aminopeptidases closely related
to E. coli PepN and presumed to have similar (not
identical) function. Nearly all are found in
Proteobacteria, but members are found also in
Cyanobacteria, plants, and apicomplexan parasites. This
family differs greatly in sequence from the family of
aminopeptidases typified by Streptomyces lividans PepN
(TIGR02412), from the membrane bound aminopeptidase N
family in animals, etc [Protein fate, Degradation of
proteins, peptides, and glycopeptides].
