>gnl|CDD|212680 cd10238, HSPA14-like_NBD, Nucleotide-binding domain of human
HSPA14 and similar proteins. Human HSPA14 (also known
as 70-kDa heat shock protein 14, HSP70L1, HSP70-4; the
gene encoding HSPA14 maps to 10p13), is
ribosome-associated and 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). HSPA14
interacts with the J-protein MPP11 to form the
mammalian ribosome-associated complex (mRAC). HSPA14
participates in a pathway along with Nijmegen breakage
syndrome 1 (NBS1, also known as p85 or nibrin), heat
shock transcription factor 4b (HSF4b), and HSPA4
(belonging to a different subfamily), that induces
tumor migration, invasion, and transformation. HSPA14
is a potent T helper cell (Th1) polarizing adjuvant
that contributes to antitumor immune responses.

>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.

heat shock proteins including HSPA4 and similar
proteins. This subgroup includes the human proteins,
HSPA4 (also known as 70-kDa heat shock protein 4,
APG-2, HS24/P52, hsp70 RY, and HSPH2; the human HSPA4
gene maps to 5q31.1), HSPA4L (also known as 70-kDa heat
shock protein 4-like, APG-1, HSPH3, and OSP94; the
human HSPA4L gene maps to 4q28), and HSPH1 (also known
as heat shock 105kDa/110kDa protein 1, HSP105; HSP105A;
HSP105B; NY-CO-25; the human HSPH1 gene maps to
13q12.3), Saccharomyces cerevisiae Sse1p and Sse2p, and
a sea urchin sperm receptor. It belongs to the 105/110
kDa heat shock protein (HSP105/110) subfamily of the
HSP70-like family, and includes proteins 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.

>gnl|CDD|212674 cd10232, ScSsz1p_like_NBD, Nucleotide-binding domain of
Saccharmomyces cerevisiae Ssz1pp and similar proteins.
Saccharomyces cerevisiae Ssz1p (also known as
/Pdr13p/YHR064C) 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). Some family members are not
chaperones but rather, function as NEFs for their Hsp70
partners, while other family members function as both
chaperones and NEFs. Ssz1 does not function as a
chaperone; it facilitates the interaction between the
HSP70 Ssb protein and its partner J-domain protein Zuo1
(also known as zuotin) on the ribosome. Ssz1 is found
in a stable heterodimer (called RAC, ribosome
associated complex) with Zuo1. Zuo1 can only stimulate
the ATPase activity of Ssb, when it is in complex with
Ssz1. Ssz1 binds ATP but neither nucleotide-binding,
hydrolysis, or its SBD, is needed for its in vivo
function.

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

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.

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

>gnl|CDD|212679 cd10237, HSPA13-like_NBD, Nucleotide-binding domain of human
HSPA13 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 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). 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.

been assigned glutamate dehydrogenase activity. The
significance of this observation is unclear; lengths of
such shadow ORFs are highly variable as if the

>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.
