>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|189009 cd09602, M1_APN_3, Peptidase M1 family containing Aminopeptidase N.
This family contains bacterial and eukaryotic
aminopeptidase N (APN; CD13; Alanyl aminopeptidase; EC
3.4.11.2), a Type II integral membrane protease
belonging to the M1 gluzincin family. 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, in higher eukaryotes,
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 predominantly
expressed on stem cells and on cells of the granulocytic
and monocytic lineages at distinct stages of
differentiation, thus considered a marker of
differentiation. Thus, APN inhibition may lead to the
development of anti-cancer and anti-inflammatory drugs.
APNs are also present in many pathogenic bacteria and
represent potential drug targets, Some APNs have been
used commercially, such as one from Lactococcus lactis
used in the food industry. APN also serves as a receptor
for coronaviruses, although the virus receptor
interaction site seems to be distinct from the enzymatic

>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.

type. This family is a subset of the members of the
zinc metallopeptidase family M1 (pfam01433), with a
single member characterized in Streptomyces lividans 66
and designated aminopeptidase N. The spectrum of
activity may differ somewhat from the aminopeptidase N
clade of E. coli and most other Proteobacteria, well
separated phylogenetically within the M1 family. The M1

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].
