>gnl|CDD|212672 cd10230, HYOU1-like_NBD, Nucleotide-binding domain of human HYOU1
and similar proteins. This subgroup includes human
HYOU1 (also known as human hypoxia up-regulated 1,
GRP170; HSP12A; ORP150; GRP-170; ORP-150; the human
HYOU1 gene maps to11q23.1-q23.3) and Saccharomyces
cerevisiae Lhs1p (also known as Cer1p, SsI1). Mammalian
HYOU1 functions as a nucleotide exchange factor (NEF)
for HSPA5 (alos known as BiP, Grp78 or HspA5) and may
also function as a HSPA5-independent chaperone. S.
cerevisiae Lhs1p, does not have a detectable endogenous
ATPase activity like canonical HSP70s, but functions as
a NEF for Kar2p; it's interaction with Kar2p is
stimulated by nucleotide-binding. In addition, Lhs1p
has a nucleotide-independent holdase activity that
prevents heat-induced aggregation of proteins in vitro.
This subgroup 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 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 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|233830 TIGR02350, prok_dnaK, chaperone protein DnaK. Members of this
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].

>gnl|CDD|212683 cd11733, HSPA9-like_NBD, Nucleotide-binding domain of human
HSPA9, 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
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); 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.

are chaperones of the endoplasmic reticulum (ER).

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.

>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
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.

family. HSP70 (70-kDa heat shock protein) family
chaperones 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

HSP70 chaperone activity is regulated by various
co-chaperones: J-domain proteins and nucleotide
exchange factors (NEFs). Some HSP70 family members are
not 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.
