>gnl|CDD|239282 cd02984, TRX_PICOT, TRX domain, PICOT (for PKC-interacting cousin
of TRX) subfamily; PICOT is a protein that interacts
with protein kinase C (PKC) theta, a calcium independent
PKC isoform selectively expressed in skeletal muscle and
T lymphocytes. PICOT contains an N-terminal TRX-like
domain, which does not contain the catalytic CXXC motif,
followed by one to three glutaredoxin domains. The
TRX-like domain is required for interaction with PKC
theta. PICOT inhibits the activation of c-Jun N-terminal
kinase and the transcription factors, AP-1 and NF-kB,
induced by PKC theta or T-cell activating stimuli.

>gnl|CDD|239326 cd03028, GRX_PICOT_like, Glutaredoxin (GRX) family, PKC-interacting
cousin of TRX (PICOT)-like subfamily; composed of PICOT
and GRX-PICOT-like proteins. The non-PICOT members of
this family contain only the GRX-like domain, whereas
PICOT contains an N-terminal TRX-like domain followed by
one to three GRX-like domains. It is interesting to note
that PICOT from plants contain three repeats of the
GRX-like domain, metazoan proteins (except for insect)
have two repeats, while fungal sequences contain only
one copy of the domain. PICOT is a protein that
interacts with protein kinase C (PKC) theta, a calcium
independent PKC isoform selectively expressed in
skeletal muscle and T lymphocytes. PICOT inhibits the
activation of c-Jun N-terminal kinase and the
transcription factors, AP-1 and NF-kB, induced by PKC
theta or T-cell activating stimuli. Both GRX and TRX
domains of PICOT are required for its activity.
Characterized non-PICOT members of this family include
CXIP1, a CAX-interacting protein in Arabidopsis
thaliana, and PfGLP-1, a GRX-like protein from
Plasmodium falciparum.

>gnl|CDD|239245 cd02947, TRX_family, TRX family; composed of two groups: Group I,
which includes proteins that exclusively encode a TRX
domain; and Group II, which are composed of fusion
proteins of TRX and additional domains. Group I TRX is a
small ancient protein that alter the redox state of
target proteins via the reversible oxidation of an
active site dithiol, present in a CXXC motif, partially
exposed at the protein's surface. TRX reduces protein
disulfide bonds, resulting in a disulfide bond at its
active site. Oxidized TRX is converted to the active
form by TRX reductase, using reducing equivalents
derived from either NADPH or ferredoxins. By altering
their redox state, TRX regulates the functions of at
least 30 target proteins, some of which are enzymes and
transcription factors. It also plays an important role
in the defense against oxidative stress by directly
reducing hydrogen peroxide and certain radicals, and by
serving as a reductant for peroxiredoxins. At least two
major types of functional TRXs have been reported in
most organisms; in eukaryotes, they are located in the
cytoplasm and the mitochondria. Higher plants contain
more types (at least 20 TRX genes have been detected in
the genome of Arabidopsis thaliana), two of which (types
f amd m) are located in the same compartment, the
chloroplast. Also included in the alignment are TRX-like
domains which show sequence homology to TRX but do not
contain the redox active CXXC motif. Group II proteins,
in addition to either a redox active TRX or a TRX-like
domain, also contain additional domains, which may or
may not possess homology to known proteins.

>gnl|CDD|239017 cd02066, GRX_family, Glutaredoxin (GRX) family; composed of GRX,
approximately 10 kDa in size, and proteins containing a
GRX or GRX-like domain. GRX is a glutathione (GSH)
dependent reductase, catalyzing the disulfide reduction
of target proteins such as ribonucleotide reductase. It
contains a redox active CXXC motif in a TRX fold and
uses a similar dithiol mechanism employed by TRXs for
intramolecular disulfide bond reduction of protein
substrates. Unlike TRX, GRX has preference for mixed GSH
disulfide substrates, in which it uses a monothiol
mechanism where only the N-terminal cysteine is
required. The flow of reducing equivalents in the GRX
system goes from NADPH -> GSH reductase -> GSH -> GRX ->
protein substrates. By altering the redox state of
target proteins, GRX is involved in many cellular
functions including DNA synthesis, signal transduction
and the defense against oxidative stress. Different
classes are known including human GRX1 and GRX2, as well
as E. coli GRX1 and GRX3, which are members of this
family. E. coli GRX2, however, is a 24-kDa protein that
belongs to the GSH S-transferase (GST) family.

regulators of G protein functions. Phd and PhLPs
specifically bind G protein betagamma (Gbg)-subunits
with high affinity, resulting in the solubilization of
Gbg from the plasma membrane and impeding G
protein-mediated signal transduction by inhibiting the
formation of a functional G protein trimer (G protein
alphabetagamma). Phd also inhibits the GTPase activity
of G protein alpha. Phd can be phosphorylated by protein
kinase A and G protein-coupled receptor kinase 2,
leading to its inactivation. Phd was originally isolated
from the retina, where it is highly expressed and has
been implicated to play an important role in light
adaptation. It is also found in the pineal gland, liver,
spleen, striated muscle and the brain. The C-terminal
domain of Phd adopts a thioredoxin fold, but it does not
contain a CXXC motif. Phd interacts with G protein beta
mostly through the N-terminal helical domain. Also
included in this family is a PhLP characterized as a
viral inhibitor of apoptosis (IAP)-associated factor,
named VIAF, that functions in caspase activation during
apoptosis.

>gnl|CDD|239259 cd02961, PDI_a_family, Protein Disulfide Isomerase (PDIa) family,
redox active TRX domains; composed of eukaryotic
proteins involved in oxidative protein folding in the
endoplasmic reticulum (ER) by acting as catalysts and
folding assistants. Members of this family include PDI
and PDI-related proteins like ERp72, ERp57 (or ERp60),
ERp44, P5, PDIR, ERp46 and the transmembrane PDIs. PDI,
ERp57, ERp72, P5, PDIR and ERp46 are all oxidases,
catalyzing the formation of disulfide bonds of newly
synthesized polypeptides in the ER. They also exhibit
reductase activity in acting as isomerases to correct
any non-native disulfide bonds, as well as chaperone
activity to prevent protein aggregation and facilitate
the folding of newly synthesized proteins. These
proteins usually contain multiple copies of a redox
active TRX (a) domain containing a CXXC motif, and may
also contain one or more redox inactive TRX-like (b)
domains. Only one a domain is required for the oxidase
function but multiple copies are necessary for the
isomerase function. The different types of PDIs may
show different substrate specificities and
tissue-specific expression, or may be induced by
stress. PDIs are in their reduced form at steady state
and are oxidized to the active form by Ero1, which is
localized in the ER through ERp44. Some members of this
family also contain a DnaJ domain in addition to the
redox active a domains; examples are ERdj5 and Pfj2.
Also included in the family is the redox inactive
N-terminal TRX-like domain of ERp29.

>gnl|CDD|239286 cd02988, Phd_like_VIAF, Phosducin (Phd)-like family, Viral
inhibitor of apoptosis (IAP)-associated factor (VIAF)
subfamily; VIAF is a Phd-like protein that functions in
caspase activation during apoptosis. It was identified
as an IAP binding protein through a screen of a human
B-cell library using a prototype IAP. VIAF lacks a
consensus IAP binding motif and while it does not
function as an IAP antagonist, it still plays a
regulatory role in the complete activation of caspases.
VIAF itself is a substrate for IAP-mediated
ubiquitination, suggesting that it may be a target of
IAPs in the prevention of cell death. The similarity of
VIAF to Phd points to a potential role distinct from
apoptosis regulation. Phd functions as a cytosolic
regulator of G protein by specifically binding to G
protein betagamma (Gbg)-subunits. The C-terminal domain
of Phd adopts a thioredoxin fold, but it does not
contain a CXXC motif. Phd interacts with G protein beta
mostly through the N-terminal helical domain.

diverse group of proteins containing a TRX-fold. Many
members contain a classic TRX domain with a redox
active CXXC motif. They function as protein disulfide
oxidoreductases (PDOs), altering the redox state of
target proteins via the reversible oxidation of their
active site dithiol. The PDO members of this
superfamily include TRX, protein disulfide isomerase
(PDI), tlpA-like, glutaredoxin, NrdH redoxin, and the
bacterial Dsb (DsbA, DsbC, DsbG, DsbE, DsbDgamma)
protein families. Members of the superfamily that do
not function as PDOs but contain a TRX-fold domain
include phosducins, peroxiredoxins and glutathione
(GSH) peroxidases, SCO proteins, GSH transferases (GST,
N-terminal domain), arsenic reductases, TRX-like
ferredoxins and calsequestrin, among others.

characterized as intermediate chains (ICs) of axonemal
outer arm dynein. Dyneins are molecular motors that
generate force against microtubules to produce cellular

Axonemal dyneins form two structures, the inner and
outer arms, which are attached to doublet microtubules
throughout the cilia and flagella. The human homolog is
the sperm-specific Sptrx-2, presumed to be a component
of the human sperm axoneme architecture. Included in
this group is another human protein, TRX-like protein 2,
a smaller fusion protein containing one TRX and one NDPK

Phd is a cytosolic regulator of G protein functions. It
specifically binds G protein betagamma (Gbg)-subunits
with high affinity, resulting in the solubilization of
Gbg from the plasma membrane. This impedes the formation
of a functional G protein trimer (G protein
alphabetagamma), thereby inhibiting G protein-mediated
signal transduction. Phd also inhibits the GTPase
activity of G protein alpha. Phd can be phosphorylated
by protein kinase A and G protein-coupled receptor
kinase 2, leading to its inactivation. Phd was
originally isolated from the retina, where it is highly
expressed and has been implicated to play an important
role in light adaptation. It is also found in the pineal
gland, liver, spleen, striated muscle and the brain. The
C-terminal domain of Phd adopts a thioredoxin fold, but
it does not contain a CXXC motif. Phd interacts with G
protein beta mostly through the N-terminal helical
domain.

class 1 and 2 (h_1_2)-like subfamily; composed of
proteins similar to human GRXs, approximately 10 kDa in
size, and proteins containing a GRX or GRX-like domain.
GRX is a glutathione (GSH) dependent reductase,
catalyzing the disulfide reduction of target proteins
such as ribonucleotide reductase. It contains a redox
active CXXC motif in a TRX fold and uses a similar
dithiol mechanism employed by TRXs for intramolecular
disulfide bond reduction of protein substrates. Unlike
TRX, GRX has preference for mixed GSH disulfide
substrates, in which it uses a monothiol mechanism where
only the N-terminal cysteine is required. The flow of
reducing equivalents in the GRX system goes from NADPH
-> GSH reductase -> GSH -> GRX -> protein substrates. By
altering the redox state of target proteins, GRX is
involved in many cellular functions including DNA
synthesis, signal transduction and the defense against
oxidative stress. Different classes are known including
human GRX1 and GRX2, which are members of this
subfamily. Also included in this subfamily are the
N-terminal GRX domains of proteins similar to human
thioredoxin reductase 1 and 3.

subfamily; composed of the C-terminal redox active a'
domains of PDI, ERp72, ERp57 (or ERp60) and EFP1. PDI,
ERp72 and ERp57 are endoplasmic reticulum (ER)-resident
eukaryotic proteins involved in oxidative protein
folding. They are oxidases, catalyzing the formation of
disulfide bonds of newly synthesized polypeptides in
the ER. They also exhibit reductase activity in acting
as isomerases to correct any non-native disulfide
bonds, as well as chaperone activity to prevent protein
aggregation and facilitate the folding of newly
synthesized proteins. PDI and ERp57 have the abb'a'
domain structure (where a and a' are redox active TRX
domains while b and b' are redox inactive TRX-like
domains). PDI also contains an acidic region (c domain)
after the a' domain that is absent in ERp57. ERp72 has
an additional a domain at the N-terminus (a"abb'a'
domain structure). ERp57 interacts with the lectin
chaperones, calnexin and calreticulin, and specifically
promotes the oxidative folding of glycoproteins, while
PDI shows a wider substrate specificity. ERp72
associates with several ER chaperones and folding
factors to form complexes in the ER that bind nascent
proteins. EFP1 is a binding partner protein of thyroid
oxidase, which is responsible for the generation of
hydrogen peroxide, a crucial substrate of
thyroperoxidase, which functions to iodinate
thyroglobulin and synthesize thyroid hormones.

thioltransferases (disulfide reductases) which utilize
glutathione and NADPH as cofactors. Oxidized glutathione
is regenerated by glutathione reductase. Together these
components compose the glutathione system. Glutaredoxins
utilize the CXXC motif common to thioredoxins and are
involved in multiple cellular processes including
protection from redox stress, reduction of critical
enzymes such as ribonucleotide reductase and the
generation of reduced sulfur for iron sulfur cluster
formation. Glutaredoxins are capable of reduction of
mixed disulfides of glutathione as well as the formation
of glutathione mixed disulfides. This family of
glutaredoxins includes the E. coli protein GrxC (Grx3)
which appears to have a secondary role in reducing
ribonucleotide reductase (in the absence of GrxA)
possibly indicating a role in the reduction of other
protein disulfides [Energy metabolism, Electron
