>gnl|CDD|107229 cd06472, ACD_ScHsp26_like, Alpha crystallin domain (ACD) found in
Saccharomyces cerevisiae (Sc) small heat shock protein
(Hsp)26 and similar proteins. sHsps are molecular
chaperones that suppress protein aggregation and protect
against cell stress, and are generally active as large
oligomers consisting of multiple subunits. ScHsp26 is
temperature-regulated, it switches from an inactive to a
chaperone-active form upon elevation in temperature. It
associates into large 24-mers storage forms which upon
heat shock disassociate into dimers. These dimers
initiate the interaction with non-native substrate
proteins and re-assemble into large globular assemblies
having one monomer of substrate bound per dimer. This
group also contains Arabidopsis thaliana (Ath) Hsp15.7,
a peroxisomal matrix protein which can complement the
morphological phenotype of S. cerevisiae mutants
deficient in Hsps26. AthHsp15.7 is minimally expressed
under normal conditions and is strongly induced by heat
and oxidative stress. Also belonging to this group is
wheat HSP16.9 which differs in quaternary structure from
the shell-type particles of ScHsp26, it assembles as a
dodecameric double disc, with each disc organized as a
trimer of dimers.

alpha-crystallin domain (ACD) of alpha-crystallin-type
small heat shock proteins (sHsps) and a similar domain
found in p23-like proteins. sHsps are small stress
induced proteins with monomeric masses between 12 -43
kDa, whose common feature is this ACD. sHsps are
generally active as large oligomers consisting of
multiple subunits, and are believed to be
ATP-independent chaperones that prevent aggregation and
are important in refolding in combination with other
Hsps. p23 is a cochaperone of the Hsp90 chaperoning
pathway. It binds Hsp90 and participates in the folding
of a number of Hsp90 clients including the progesterone
receptor. p23 also has a passive chaperoning activity.
p23 in addition may act as the cytosolic prostaglandin
E2 synthase. Included in this family is the p23-like
C-terminal CHORD-SGT1 (CS) domain of suppressor of G2
allele of Skp1 (Sgt1) and the p23-like domains of human
butyrate-induced transcript 1 (hB-ind1), NUD (nuclear
distribution) C, Melusin, and NAD(P)H cytochrome b5
(NCB5) oxidoreductase (OR).

alpha crystallin domain (ACD) similar to Lactobacillus
plantarum (Lp) small heat shock proteins (sHsp) HSP
18.5, HSP 18.55 and HSP 19.3. sHsps are molecular
chaperones that suppress protein aggregation and protect
against cell stress, and are generally active as large
oligomers consisting of multiple subunits. Transcription
of the genes encoding Lp HSP 18.5, 18.55 and 19.3 is
regulated by a variety of stresses including heat, cold
and ethanol. Early growing L. plantarum cells contain
elevated levels of these mRNAs which rapidly fall of as
the cells enter stationary phase. Also belonging to this
group is Bifidobacterium breve (Bb) HSP20 and Oenococcus
oenis (syn. Leuconostoc oenos) (Oo) HSP18.
Transcription of the gene encoding BbHSP20 is strongly
induced following heat or osmotic shock, and that of the
gene encoding OoHSP18 following heat, ethanol or acid
shock. OoHSP18 is peripherally associated with the
cytoplasmic membrane.

>gnl|CDD|107227 cd06470, ACD_IbpA-B_like, Alpha-crystallin domain (ACD) found in
Escherichia coli inclusion body-associated proteins IbpA
and IbpB, and similar proteins. IbpA and IbpB are 16
kDa small heat shock proteins (sHsps). sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. IbpA and IbpB are produced during high-level
production of various heterologous proteins,
specifically human prorenin, renin and bovine
insulin-like growth factor 2 (bIGF-2), and are strongly
associated with inclusion bodies containing these
heterologous proteins. IbpA and IbpB work as an
integrated system to stabilize thermally aggregated
proteins in a disaggregation competent state. The
chaperone activity of IbpB is also significantly
elevated as the temperature increases from normal to
heat shock. The high temperature results in the
disassociation of 2-3-MDa IbpB oligomers into smaller
approximately 600-kDa structures. This elevated activity
seen under heat shock conditions is retained for an
extended period of time after the temperature is
returned to normal. IbpA also forms multimers.

mammalian small (s)heat shock protein (Hsp)-27 (also
denoted HspB1 in human) and similar proteins. sHsps are
molecular chaperones that suppress protein aggregation
and protect against cell stress, and are generally
active as large oligomers consisting of multiple
subunits. Hsp27 shows enhanced synthesis in response to
stress. It is a molecular chaperone which interacts with
a large number of different proteins. It is found in
many types of human cells including breast, uterus,
cervix, platelets and cancer cells. Hsp27 has diverse
cellular functions including, chaperoning, regulation of
actin polymerization, keratinocyte differentiation,
regulation of inflammatory pathways in keratinocytes,
and protection from oxidative stress through modulating
glutathione levels. It is also a subunit of
AUF1-containing protein complexes. It has been linked to
several transduction pathways regulating cellular
functions including differentiation, cell growth,
development, and apoptosis. Its activity can be
regulated by phosphorylation. Its unphosphorylated state
is a high molecular weight aggregated form (100-800kDa)
composed of up to 24 subunits, which forms as a result
of multiple interactions within the ACD, and is required
for chaperone function and resistance to oxidative
stress. Upon phosphorylation these large aggregates
rapidly disassociate to smaller oligomers and chaperone
activity is modified. High constitutive levels of Hsp27
have been detected in various cancer cells, in
particular those of carcinoma origin. Over-expression of
Hsp27 has a protective effect against various
diseases-processes, including Huntington's disease.
Mutations in Hsp27 have been associated with a form of
distal hereditary motor neuropathy type II and
Charcot-Marie-Tooth disease type 2.

>gnl|CDD|107220 cd06463, p23_like, Proteins containing this p23_like domain include
p23 and its Saccharomyces cerevisiae (Sc) homolog Sba1.
Both are co-chaperones for the heat shock protein (Hsp)
90. p23 binds Hsp90 and participates in the folding of
a number of Hsp90 clients, including the progesterone
receptor. p23 also has a passive chaperoning activity
and in addition may participate in prostaglandin
synthesis. Both p23 and Sba1p can regulate telomerase
activity. This group includes domains similar to the
C-terminal CHORD-SGT1 (CS) domain of suppressor of G2
allele of Skp1 (Sgt1). Sgt1 interacts with multiple
protein complexes and has the features of a
co-chaperone. Human (h) Sgt1 interacts with both Hsp70
and Hsp90, and has been shown to bind Hsp90 through its
CS domain. Saccharomyces cerevisiae (Sc) Sgt1 is a
subunit of both core kinetochore and SCF
(Skp1-Cul1-F-box) ubiquitin ligase complexes. Sgt1 is
required for pathogen resistance in plants. This group
also includes the p23_like domains of human
butyrate-induced transcript 1 (hB-ind1), NUD (nuclear
distribution) C, Melusin, and NAD(P)H cytochrome b5
(NCB5) oxidoreductase (OR). hB-ind1 plays a role in the
signaling pathway mediated by the small GTPase Rac1,
NUDC is needed for nuclear movement, Melusin interacts
with two splice variants of beta1 integrin, and NCB5OR
plays a part in maintaining viable pancreatic beta
cells.

alphaA-crystallin (HspB4), alphaB-crystallin (HspB5),
and the small heat shock protein (sHsp) HspB6, also
known as Hsp20. sHsps are molecular chaperones that
suppress protein aggregation and protect against cell
stress, and are generally active as large oligomers
consisting of multiple subunits. Alpha crystallin, an
abundant protein in the mammalian lens, is a large (700
kDa) heteropolymer composed of HspB4 and HspB5,
generally in a molar ratio of HspB4:HspB5 of 3:1. Only
trace amounts of HspB4 are found in tissues other than
the lens. HspB5 on the other hand is also expressed
constitutively in other tissues including brain, heart,
and type I and type IIa skeletal muscle fibers, and in
several cancers including gliomas, renal cell
carcinomas, basal-like and metaplastic breast
carcinomas, and head and neck cancer. HspB5's functions
include effects on the apoptotic pathway and on
metastasis. Phosphorylation of HspB5 reduces its
oligomerization and anti-apoptotic activities. HspB5 is
protective in demyelinating disease such as multiple
sclerosis (MS), being a negative regulator of
inflammation. In early active MS lesions it is the most
abundant gene transcript and an autoantigen, the immune
response against it would disrupt its function and
worsen inflammation and demyelination. Given as therapy
for ongoing demyelinating disease it may counteract this
effect. It is an autoantigen in the pathogenesis of
various other inflammatory disorders including
Lens-associated uveitis (LAU), and Behcet's disease.
Mutations in HspB5 have been associated with diseases
including dominant cataract and desmin-related myopathy.
Mutations in HspB4 have been associated with Autosomal
Dominant Congenital Cataract (ADCC). HspB6 (Hsp20) is
ubiquitous and is involved in diverse functions
including regulation of glucose transport and
contraction of smooth muscle, in platelet aggregation,
in cardioprotection, and in the prevention of apoptosis.
It interacts with the universal scaffolding and adaptor
protein 14-3-3, and also with the proapoptotic protein
Bax.

27-like protein (HSPL27, 17-kDa) and similar proteins.
sHsps are molecular chaperones that suppress protein
aggregation and protect against cell stress, and are
generally active as large oligomers consisting of
multiple subunits. HspB3 is expressed in adult skeletal
muscle, smooth muscle, and heart, and in several other
fetal tissues. In muscle cells HspB3 forms an
oligomeric 150 kDa complex with myotonic dystrophy
protein kinase-binding protein (MKBP/ HspB2), this
complex may comprise one of two independent muscle-cell
specific chaperone systems. The expression of HspB3 is
induced during muscle differentiation controlled by the
myogenic factor MyoD. HspB3 may also interact with Hsp22
(HspB8).

related eicosanoids are metabolized by the oxidation of
the 15(S)-hydroxyl group of the NAD+-dependent (type I
15-PGDH) 15-prostaglandin dehydrogenase (15-PGDH)
followed by reduction by NADPH/NADH-dependent (type II
15-PGDH) delta-13 15-prostaglandin reductase (13-PGR) to
15-keto-13,14,-dihydroprostaglandins. 13-PGR is a
bifunctional enzyme, since it also has leukotriene B(4)
12-hydroxydehydrogenase activity. These 15-PGDH and
related enzymes are members of the medium chain
dehydrogenase/reductase family. The medium chain
dehydrogenases/reductase (MDR)/zinc-dependent alcohol
dehydrogenase-like family, which contains the
zinc-dependent alcohol dehydrogenase (ADH-Zn) and
related proteins, is a diverse group of proteins related
to the first identified member, class I mammalian ADH.
MDRs display a broad range of activities and are
distinguished from the smaller short chain
dehydrogenases (~ 250 amino acids vs. the ~ 350 amino
acids of the MDR). The MDR proteins have 2 domains: a
C-terminal NAD(P) binding-Rossmann fold domain of a
beta-alpha form and an N-terminal catalytic domain with
distant homology to GroES.

enzyme acts on the most common type of naturally

phosphonoacetaldehyde hydrolase (EC 3.11.1.1), usually
encoded by an adjacent gene, then cleaves the C-P bond
of phosphonoacetaldehyde, adding water to yield
acetaldehyde plus inorganic phosphate. Species with this

contains 8-13 transmembrane helices and can function
either independently as a chemiosmotic transporter or as
a channel-forming subunit of an ATP-driven anion pump
(ArsAB). The ArsAB complex is similar in many ways to
ATP-binding cassette transporters, which have two groups
of six transmembrane-spanning helical segments and two
nucleotide-binding domains. The ArsB proteins belong to
the ArsB/NhaD superfamily of permeases that translocate
sodium, arsenate, sulfate, and organic anions across
biological membranes in all three kingdoms of life.

Molecular chaperones transiently interact with unfolded

not share similarities. However, their folding does
require BiP, and one of these proteins was

17. Formin Binding Protein 17 (FBP17), also called
FormiN Binding Protein 1 (FNBP1), is involved in
dynamin-mediated endocytosis. It is recruited to
clathrin-coated pits late in the endocytosis process and
may play a role in the invagination and scission steps.
FBP17 binds in vivo to tankyrase, a protein involved in
telomere maintenance and mitogen activated protein
kinase (MAPK) signaling. It contains an N-terminal F-BAR
(FES-CIP4 Homology and Bin/Amphiphysin/Rvs) domain, a
Cdc42-binding HR1 domain, and a C-terminal SH3 domain.
The SH3 domain of the related protein, CIP4, associates
with Gapex-5, a Rab31 GEF. 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.

receptors, the apolipoprotein E receptor 2 (ApoER2) and
the very-low-density lipoprotein receptor (VLDLR),
