>gnl|CDD|239111 cd02620, Peptidase_C1A_CathepsinB, Cathepsin B group; composed of
cathepsin B and similar proteins, including
tubulointerstitial nephritis antigen (TIN-Ag). Cathepsin
B is a lysosomal papain-like cysteine peptidase which is
expressed in all tissues and functions primarily as an
exopeptidase through its carboxydipeptidyl activity.
Together with other cathepsins, it is involved in the
degradation of proteins, proenzyme activation, Ag
processing, metabolism and apoptosis. Cathepsin B has
been implicated in a number of human diseases such as
cancer, rheumatoid arthritis, osteoporosis and
Alzheimer's disease. The unique carboxydipeptidyl
activity of cathepsin B is attributed to the presence of
an occluding loop in its active site which favors the
binding of the C-termini of substrate proteins. Some
members of this group do not possess the occluding loop.
TIN-Ag is an extracellular matrix basement protein which
was originally identified as a target Ag involved in
anti-tubular basement membrane antibody-mediated
interstitial nephritis. It plays a role in renal
tubulogenesis and is defective in hereditary
tubulointerstitial disorders. TIN-Ag is exclusively
expressed in kidney tissues. .

>gnl|CDD|239112 cd02621, Peptidase_C1A_CathepsinC, Cathepsin C; also known as
Dipeptidyl Peptidase I (DPPI), an atypical papain-like
cysteine peptidase with chloride dependency and
dipeptidyl aminopeptidase activity, resulting from its
tetrameric structure which limits substrate access. Each
subunit of the tetramer is composed of three peptides:
the heavy and light chains, which together adopts the
papain fold and forms the catalytic domain; and the
residual propeptide region, which forms a beta barrel
and points towards the substrate's N-terminus. The
subunit composition is the result of the unique
characteristic of procathepsin C maturation involving
the cleavage of the catalytic domain and the
non-autocatalytic excision of an activation peptide
within its propeptide region. By removing N-terminal
dipeptide extensions, cathepsin C activates granule
serine peptidases (granzymes) involved in cell-mediated
apoptosis, inflammation and tissue remodelling.
Loss-of-function mutations in cathepsin C are associated
with Papillon-Lefevre and Haim-Munk syndromes, rare
diseases characterized by hyperkeratosis and early-onset
periodontitis. Cathepsin C is widely expressed in many
tissues with high levels in lung, kidney and placenta.
It is also highly expressed in cytotoxic lymphocytes and
mature myeloid cells.

>gnl|CDD|239068 cd02248, Peptidase_C1A, Peptidase C1A subfamily (MEROPS database
nomenclature); composed of cysteine peptidases (CPs)
similar to papain, including the mammalian CPs
(cathepsins B, C, F, H, L, K, O, S, V, X and W). Papain
is an endopeptidase with specific substrate preferences,
primarily for bulky hydrophobic or aromatic residues at
the S2 subsite, a hydrophobic pocket in papain that
accommodates the P2 sidechain of the substrate (the
second residue away from the scissile bond). Most
members of the papain subfamily are endopeptidases. Some
exceptions to this rule can be explained by specific
details of the catalytic domains like the occluding loop
in cathepsin B which confers an additional
carboxydipeptidyl activity and the mini-chain of
cathepsin H resulting in an N-terminal exopeptidase
activity. Papain-like CPs have different functions in
various organisms. Plant CPs are used to mobilize
storage proteins in seeds. Parasitic CPs act
extracellularly to help invade tissues and cells, to
hatch or to evade the host immune system. Mammalian CPs
are primarily lysosomal enzymes with the exception of
cathepsin W, which is retained in the endoplasmic
reticulum. They are responsible for protein degradation
in the lysosome. Papain-like CPs are synthesized as
inactive proenzymes with N-terminal propeptide regions,
which are removed upon activation. In addition to its
inhibitory role, the propeptide is required for proper
folding of the newly synthesized enzyme and its
stabilization in denaturing pH conditions. Residues
within the propeptide region also play a role in the
transport of the proenzyme to lysosomes or acidified
vesicles. Also included in this subfamily are proteins
classified as non-peptidase homologs, which lack
peptidase activity or have missing active site residues.

>gnl|CDD|239149 cd02698, Peptidase_C1A_CathepsinX, Cathepsin X; the only
papain-like lysosomal cysteine peptidase exhibiting
carboxymonopeptidase activity. It can also act as a
carboxydipeptidase, like cathepsin B, but has been shown
to preferentially cleave substrates through a
monopeptidyl carboxypeptidase pathway. The propeptide
region of cathepsin X, the shortest among papain-like
peptidases, is covalently attached to the active site
cysteine in the inactive form of the enzyme. Little is
known about the biological function of cathepsin X. Some
studies point to a role in early tumorigenesis. A more
recent study indicates that cathepsin X expression is
restricted to immune cells suggesting a role in
phagocytosis and the regulation of the immune response.

>gnl|CDD|239110 cd02619, Peptidase_C1, C1 Peptidase family (MEROPS database
nomenclature), also referred to as the papain family;
composed of two subfamilies of cysteine peptidases
(CPs), C1A (papain) and C1B (bleomycin hydrolase).
Papain-like enzymes are mostly endopeptidases with some
exceptions like cathepsins B, C, H and X, which are
exopeptidases. Papain-like CPs have different functions
in various organisms. Plant CPs are used to mobilize
storage proteins in seeds while mammalian CPs are
primarily lysosomal enzymes responsible for protein
degradation in the lysosome. Papain-like CPs are
synthesized as inactive proenzymes with N-terminal
propeptide regions, which are removed upon activation.
Bleomycin hydrolase (BH) is a CP that detoxifies
bleomycin by hydrolysis of an amide group. It acts as a
carboxypeptidase on its C-terminus to convert itself
into an aminopeptidase and peptide ligase. BH is found
in all tissues in mammals as well as in many other
eukaryotes. It forms a hexameric ring barrel structure
with the active sites imbedded in the central channel.
Some members of the C1 family are proteins classified as
non-peptidase homologs which lack peptidase activity or
have missing active site residues.

>gnl|CDD|212954 cd12021, SH3_p47phox_1, First or N-terminal Src homology 3 domain
of the p47phox subunit of NADPH oxidase, also called
Neutrophil Cytosolic Factor 1. p47phox, or NCF1, is a
cytosolic subunit of the phagocytic NADPH oxidase
complex (also called Nox2 or gp91phox), which plays a
key role in the ability of phagocytes to defend against
bacterial infections. NADPH oxidase catalyzes the
transfer of electrons from NADPH to oxygen during
phagocytosis forming superoxide and reactive oxygen
species. p47phox is required for activation of NADH
oxidase and plays a role in translocation. It contains
an N-terminal Phox homology (PX) domain, tandem SH3
domains (N-SH3 and C-SH3), a polybasic/autoinhibitory
region, and a C-terminal proline-rich region (PRR). This
model characterizes the first SH3 domain (or N-SH3) of
p47phox. In its inactive state, the tandem SH3 domains
interact intramolecularly with the autoinhibitory
region; upon activation, the tandem SH3 domains are
exposed through a conformational change, resulting in
their binding to the PRR of p22phox and the activation
of NADPH oxidase. SH3 domains are protein interaction
domains that bind to proline-rich ligands with moderate
affinity and selectivity, preferentially to PxxP motifs.
They play versatile and diverse roles in the cell
including the regulation of enzymes, changing the
subcellular localization of signaling pathway
components, and mediating the formation of multiprotein
complex assemblies.
