>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.

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

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|189006 cd09599, M1_LTA4H, Peptidase M1 family contains leukotriene A4
hydrolase. This family includes leukotriene A4
hydrolase (LTA4H; E.C. 3.3.2.6) and the close homolog
cold-active aminopeptidase (Colwellia
psychrerythraea-type peptidase; ColAP), both members of
the aminopeptidase M1 family. 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 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. It accepts a variety of substrates,
including some opioid, di- and tripeptides, as well as
chromogenic aminoacyl-p-nitroanilide derivatives. The
aminopeptidase activity of LTA4H is possibly involved in
the processing of peptides related to inflammation and
host defense. Kinetic analysis shows that LTA4H
hydrolyzes arginyl tripeptides with high efficiency and
specificity, indicating its function as an arginyl
aminopeptidase. LTA4H is overexpressed in certain human
cancers, and has been identified as a functionally
important target for mediating anticancer properties of
resveratrol, a well known red wine polyphenolic compound
with cancer chemopreventive activity.

>gnl|CDD|240817 cd12371, RRM2_PUF60, RNA recognition motif 2 in
(U)-binding-splicing factor PUF60 and similar proteins.
This subfamily corresponds to the RRM2 of PUF60, also
termed FUSE-binding protein-interacting repressor
(FBP-interacting repressor or FIR), or Ro-binding
protein 1 (RoBP1), or Siah-binding protein 1 (Siah-BP1).
PUF60 is an essential splicing factor that functions as
a poly-U RNA-binding protein required to reconstitute
splicing in depleted nuclear extracts. Its function is
enhanced through interaction with U2 auxiliary factor
U2AF65. PUF60 also controls human c-myc gene expression
by binding and inhibiting the transcription factor far
upstream sequence element (FUSE)-binding-protein (FBP),
an activator of c-myc promoters. PUF60 contains two
central RNA recognition motifs (RRMs), also termed RBDs
(RNA binding domains) or RNPs (ribonucleoprotein
domains), and a C-terminal U2AF (U2 auxiliary factor)
homology motifs (UHM) that harbors another RRM and binds
to tryptophan-containing linear peptide motifs (UHM
ligand motifs, ULMs) in several nuclear proteins.
Research indicates that PUF60 binds FUSE as a dimer, and
only the first two RRM domains participate in the
single-stranded DNA recognition. .
