>gnl|CDD|212681 cd10241, HSPA5-like_NBD, Nucleotide-binding domain of human HSPA5
and similar proteins. This subfamily includes human
HSPA5 (also known as 70-kDa heat shock protein 5,
glucose-regulated protein 78/GRP78, and immunoglobulin
heavy chain-binding protein/BIP, MIF2; the gene encoding
HSPA5 maps to 9q33.3.), Sacchaormyces cerevisiae Kar2p
(also known as Grp78p), and related proteins. This
subfamily belongs to the heat shock protein 70 (HSP70)
family of chaperones that assist in protein folding and
assembly and can direct incompetent "client" proteins
towards degradation. HSPA5 and Kar2p are chaperones of
the endoplasmic reticulum (ER). Typically, HSP70s have a
nucleotide-binding domain (NBD) and a substrate-binding
domain (SBD). The nucleotide sits in a deep cleft formed
between the two lobes of the NBD. The two subdomains of
each lobe change conformation between ATP-bound,
ADP-bound, and nucleotide-free states. ATP binding opens
up the substrate-binding site; substrate-binding
increases the rate of ATP hydrolysis. HSP70 chaperone
activity is regulated by various co-chaperones: J-domain
proteins and nucleotide exchange factors (NEFs).
Multiple ER DNAJ domain proteins have been identified
and may exist in distinct complexes with HSPA5 in
various locations in the ER, for example DNAJC3-p58IPK
in the lumen. HSPA5-NEFs include SIL1 and an atypical
HSP70 family protein HYOU1/ORP150. The ATPase activity
of Kar2p is stimulated by the NEFs: Sil1p and Lhs1p.

HSPA1-A, -B, -L, HSPA-2, -6, -7, -8, and similar
proteins. This subfamily includes human HSPA1A (70-kDa
heat shock protein 1A, also known as HSP72; HSPA1;
HSP70I; HSPA1B; HSP70-1; HSP70-1A), HSPA1B (70-kDa heat
shock protein 1B, also known as HSPA1A; HSP70-2;
HSP70-1B), and HSPA1L (70-kDa heat shock protein 1-like,
also known as HSP70T; hum70t; HSP70-1L; HSP70-HOM). The
genes for these three HSPA1 proteins map in close
proximity on the major histocompatibility complex (MHC)
class III region on chromosome 6, 6p21.3. This subfamily
also includes human HSPA8 (heat shock 70kDa protein 8,
also known as LAP1; HSC54; HSC70; HSC71; HSP71; HSP73;
NIP71; HSPA10; the HSPA8 gene maps to 11q24.1), human
HSPA2 (70-kDa heat shock protein 2, also known as
HSP70-2; HSP70-3, the HSPA2 gene maps to 14q24.1), human
HSPA6 (also known as heat shock 70kDa protein 6
(HSP70B') gi 94717614, the HSPA6 gene maps to 1q23.3),
human HSPA7 (heat shock 70kDa protein 7 , also known as
HSP70B; the HSPA7 gene maps to 1q23.3) and Saccharmoyces
cerevisiae Stress-Seventy subfamily B/Ssb1p. This
subfamily belongs to the heat shock protein 70 (HSP70)
family of chaperones that assist in protein folding and
assembly and can direct incompetent "client" proteins
towards degradation. Typically, HSP70s have a
nucleotide-binding domain (NBD) and a substrate-binding
domain (SBD). The nucleotide sits in a deep cleft formed
between the two lobes of the NBD. The two subdomains of
each lobe change conformation between ATP-bound,
ADP-bound, and nucleotide-free states. ATP binding opens
up the substrate-binding site; substrate-binding
increases the rate of ATP hydrolysis. HSP70 chaperone
activity is regulated by various co-chaperones: J-domain
proteins and nucleotide exchange factors (NEFs).
Associations of polymorphisms within the MHC-III HSP70
gene locus with longevity, systemic lupus erythematosus,
Meniere's disease, noise-induced hearing loss,
high-altitude pulmonary edema, and coronary heart
disease, have been found. HSPA2 is involved in cancer
cell survival, is required for maturation of male
gametophytes, and is linked to male infertility. The
induction of HSPA6 is a biomarker of cellular stress.
HSPA8 participates in the folding and trafficking of
client proteins to different subcellular compartments,
and in the signal transduction and apoptosis process; it
has been shown to protect cardiomyocytes against
oxidative stress partly through an interaction with
alpha-enolase. S. cerevisiae Ssb1p, is part of the
ribosome-associated complex (RAC), it acts as a
chaperone for nascent polypeptides, and is important for
translation fidelity; Ssb1p is also a [PSI+]
prion-curing factor.

chaperones but instead, function as NEFs to remove ADP
from their HSP70 chaperone partners during the ATP
hydrolysis cycle, some may function as both chaperones
and NEFs.

family are the chaperone DnaK, of the DnaK-DnaJ-GrpE
chaperone system. All members of the seed alignment were
taken from completely sequenced bacterial or archaeal
genomes and (except for Mycoplasma sequence) found
clustered with other genes of this systems. This model
excludes DnaK homologs that are not DnaK itself, such as
the heat shock cognate protein HscA (TIGR01991).
However, it is not designed to distinguish among DnaK
paralogs in eukaryotes. Note that a number of dnaK genes
have shadow ORFs in the same reverse (relative to dnaK)
reading frame, a few of which have been assigned
glutamate dehydrogenase activity. The significance of
this observation is unclear; lengths of such shadow ORFs
are highly variable as if the presumptive protein
product is not conserved [Protein fate, Protein folding
and stabilization].

and similar proteins. Human HSPA13 (also called 70-kDa
heat shock protein 13, STCH, "stress 70 protein
chaperone, microsome-associated, 60kD", "stress 70
protein chaperone, microsome-associated, 60kDa"; the
gene encoding HSPA13 maps to 21q11.1) belongs to the
heat shock protein 70 (HSP70) family of chaperones that
assist in protein folding and assembly and can direct
incompetent "client" proteins towards degradation.
Typically, HSP70s have a nucleotide-binding domain (NBD)
and a substrate-binding domain (SBD). The nucleotide

HSP70 chaperone activity is regulated by various
co-chaperones: J-domain proteins and nucleotide exchange
factors (NEFs). STCH contains an NBD but lacks an SBD.
STCH may function to regulate cell proliferation and
survival, and modulate the TRAIL-mediated cell death
pathway. The HSPA13 gene is a candidate stomach cancer
susceptibility gene; a mutation in the NBD coding region
of HSPA13 has been identified in stomach cancer cells.
The NBD of HSPA13 interacts with the ubiquitin-like
proteins Chap1 and Chap2, implicating HSPA13 in
regulating cell cycle and cell death events. HSPA13 is
induced by the Ca2+ ionophore A23187.

Escherichia coli DnaK, and similar proteins. This
subgroup includes human mitochondrial HSPA9 (also known
as 70-kDa heat shock protein 9, CSA; MOT; MOT2; GRP75;
PBP74; GRP-75; HSPA9B; MTHSP75; the gene encoding HSPA9
maps to 5q31.1), Escherichia coli DnaK, and
Saccharomyces cerevisiae Stress-Seventy subfamily
C/Ssc1p (also called mtHSP70, Endonuclease SceI 75 kDa
subunit). It belongs to the heat shock protein 70
(HSP70) family of chaperones that assist in protein
folding and assembly, and can direct incompetent
"client" proteins towards degradation. Typically, HSP70s
have a nucleotide-binding domain (NBD) and a

two subdomains of each lobe change conformation between
ATP-bound, ADP-bound, and nucleotide-free states. ATP
binding opens up the substrate-binding site;
substrate-binding increases the rate of ATP hydrolysis.
Hsp70 chaperone activity is regulated by various
co-chaperones: J-domain proteins and nucleotide exchange
factors (NEFs); for Escherichia coli DnaK, these are the
DnaJ and GrpE, respectively. HSPA9 is involved in
multiple processses including mitochondrial import,
antigen processing, control of cellular proliferation
and differentiation, and regulation of glucose
responses. During glucose deprivation-induced cellular
stress, HSPA9 plays an important role in the suppression
of apoptosis by inhibiting a conformational change in
Bax that allow the release of cytochrome c. DnaK
modulates the heat shock response in Escherichia coli.
It protects E. coli from protein carbonylation, an
irreversible oxidative modification that increases
during organism aging and bacterial growth arrest. Under
severe thermal stress, it functions as part of a
bi-chaperone system: the DnaK system and the
ring-forming AAA+ chaperone ClpB (Hsp104) system, to
promote cell survival. DnaK has also been shown to
cooperate with GroEL and the ribosome-associated
Escherichia coli Trigger Factor in the proper folding of
cytosolic proteins. S. cerevisiae Ssc1p is the major
HSP70 chaperone of the mitochondrial matrix, promoting
translocation of proteins from the cytosol, across the
inner membrane, to the matrix, and their subsequent
folding. Ssc1p interacts with Tim44, a peripheral inner
membrane protein associated with the TIM23 protein
translocase. It is also a subunit of the endoSceI
site-specific endoDNase and is required for full
endoSceI activity. Ssc1p plays roles in the import of
Yfh1p, a nucleus-encoded mitochondrial protein involved
in iron homeostasis (and a homolog of human frataxin,
implicated in the neurodegenerative disease,
Friedreich's ataxia). Ssc1 also participates in
translational regulation of cytochrome c oxidase (COX)
biogenesis by interacting with Mss51 and
Mss51-containing complexes.

cerevisiae Ssq1 and similar proteins. Ssq1p (also
called Stress-seventy subfamily Q protein 1, Ssc2p,
Ssh1p, mtHSP70 homolog) belongs to the heat shock
protein 70 (HSP70) family of chaperones that assist in
protein folding and assembly, and can direct incompetent
"client" proteins towards degradation. Typically, HSP70s
have a nucleotide-binding domain (NBD) and a
substrate-binding domain (SBD). The nucleotide sits in a
deep cleft formed between the two lobes of the NBD. The
two subdomains of each lobe change conformation between
ATP-bound, ADP-bound, and nucleotide-free states. ATP
binding opens up the substrate-binding site;
substrate-binding increases the rate of ATP hydrolysis.
Hsp70 chaperone activity is regulated by various
co-chaperones: J-domain proteins and nucleotide exchange
factors (NEFs). S. cerevisiae Ssq1p is a mitochondrial
chaperone that is involved in iron-sulfur (Fe/S) center
biogenesis. Ssq1p plays a role in the maturation of
Yfh1p, a nucleus-encoded mitochondrial protein involved
in iron homeostasis (and a homolog of human frataxin,
implicated in the neurodegenerative disease,
Friedreich's ataxia).

it is in complex with Ssz1. Ssz1 binds ATP but neither
nucleotide-binding, hydrolysis, or its SBD, is needed
for its in vivo function.

C-terminal substrate-binding domain (SBD). For HSP70
chaperones, the nucleotide sits in a deep cleft formed
between the two lobes of the NBD. The two subdomains of
each lobe change conformation between ATP-bound,
ADP-bound, and nucleotide-free states. ATP binding opens
up the substrate-binding site; substrate-binding
increases the rate of ATP hydrolysis. HSP70 chaperone
activity is also regulated by J-domain proteins.

>gnl|CDD|212673 cd10231, YegD_like, Escherichia coli YegD, a putative chaperone
protein, and related proteins. This bacterial subfamily
includes the uncharacterized Escherichia coli YegD. It
belongs to the heat shock protein 70 (HSP70) family of
chaperones that assist in protein folding and assembly
and can direct incompetent "client" proteins towards
degradation. Typically, HSP70s have a nucleotide-binding
domain (NBD) and a substrate-binding domain (SBD). The
nucleotide sits in a deep cleft formed between the two
lobes of the NBD. The two subdomains of each lobe change
conformation between ATP-bound, ADP-bound, and
nucleotide-free states. ATP binding opens up the
substrate-binding site; substrate-binding increases the
rate of ATP hydrolysis. YegD lacks the SBD. HSP70
chaperone activity is regulated by various
co-chaperones: J-domain proteins and nucleotide exchange
factors (NEFs). Some family members are not chaperones
but instead, function as NEFs for their Hsp70 partners,
other family members function as both chaperones and
NEFs.

>gnl|CDD|212689 cd11739, HSPH1_NBD, Nucleotide-binding domain of HSPH1. Human
HSPH1 (also known as heat shock 105kDa/110kDa protein 1,
HSP105; HSP105A; HSP105B; NY-CO-25; the human HSPH1 gene
maps to 13q12.3) suppresses the aggregation of denatured
proteins caused by heat shock in vitro, and may
substitute for HSP70 family proteins to suppress the
aggregation of denatured proteins in cells under severe
stress. It reduces the protein aggregation and
cytotoxicity associated with Polyglutamine (PolyQ)
diseases, including Huntington's disease, which are a
group of inherited neurodegenerative disorders sharing
the characteristic feature of having insoluble protein
aggregates in neurons. The expression of HSPH1 is
elevated in various malignant tumors, including
malignant melanoma, and there is a direct correlation
between HSPH1 expression and B-cell non-Hodgkin
lymphomas (B-NHLs) aggressiveness and proliferation.
HSPH1 belongs to the 105/110 kDa heat shock protein
(HSP105/110) subfamily of the HSP70-like family.
HSP105/110s are believed to function generally as
co-chaperones of HSP70 chaperones, acting as nucleotide
exchange factors (NEFs), to remove ADP from their HSP70
chaperone partners during the ATP hydrolysis cycle.
HSP70 chaperones assist in protein folding and assembly,
and can direct incompetent "client" proteins towards
degradation. Like HSP70 chaperones, HSP105/110s have an
N-terminal nucleotide-binding domain (NBD) and a
C-terminal substrate-binding domain (SBD). For HSP70

each lobe change conformation between ATP-bound,

activity is also regulated by J-domain proteins.

(GATase1)-like domain found in Human DJ-1. Type 1
glutamine amidotransferase (GATase1)-like domain found
in Human DJ-1. DJ-1 is involved in multiple
physiological processes including cancer, Parkinson's
disease and male fertility. It is unclear how DJ-1
functions in these. DJ-1 has been shown to possess
chaperone activity. DJ-1 is preferentially expressed in
the testis and moderately in other tissues; it is
induced together with genes involved in oxidative
stress response. The Drosophila homologue (DJ-1A) plays
an essential role in oxidative stress response and
neuronal maintenance. Inhibition of DJ-1A function
through RNAi, results in the cellular accumulation of
reactive oxygen species, organismal hypersensitivity to
oxidative stress, and dysfunction and degeneration of
dopaminergic and photoreceptor neurons. DJ-1 has lacks
enzymatic activity and the catalytic triad of typical
GATase1 domains, however it does contain the highly
conserved cysteine located at the nucelophile elbow
region typical of these domains. This cysteine been
proposed to be a site of regulation of DJ-1 activity by
oxidation. DJ-1 is a dimeric enzyme.
