>gnl|CDD|212675 cd10233, HSPA1-2_6-8-like_NBD, Nucleotide-binding domain of
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.

>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.

>gnl|CDD|212670 cd10228, HSPA4_like_NDB, Nucleotide-binding domain of 105/110 kDa
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|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.

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

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.

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

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.

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].

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.

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.

nuclear ribonucleoprotein auxiliary factor U2AF 65 kDa
subunit (U2AF65) and similar proteins. This subfamily
corresponds to the RRM3 of U2AF65 and dU2AF50. U2AF65,
also termed U2AF2, is the large subunit of U2 small
nuclear ribonucleoprotein (snRNP) auxiliary factor
(U2AF), which has been implicated in the recruitment of
U2 snRNP to pre-mRNAs and is a highly conserved
heterodimer composed of large and small subunits.
U2AF65 specifically recognizes the intron
polypyrimidine tract upstream of the 3' splice site and
promotes binding of U2 snRNP to the pre-mRNA
branchpoint. U2AF65 also plays an important role in the
nuclear export of mRNA. It facilitates the formation of
a messenger ribonucleoprotein export complex,
containing both the NXF1 receptor and the RNA
substrate. Moreover, U2AF65 interacts directly and
specifically with expanded CAG RNA, and serves as an
adaptor to link expanded CAG RNA to NXF1 for RNA
export. U2AF65 contains an N-terminal RS domain rich in
arginine and serine, followed by a proline-rich segment
and three C-terminal RNA recognition motifs (RRMs),
also termed RBDs (RNA binding domains) or RNPs
(ribonucleoprotein domains). The N-terminal RS domain
stabilizes the interaction of U2 snRNP with the branch
point (BP) by contacting the branch region, and further
promotes base pair interactions between U2 snRNA and
the BP. The proline-rich segment mediates
protein-protein interactions with the RRM domain of the
small U2AF subunit (U2AF35 or U2AF1). The RRM1 and RRM2
are sufficient for specific RNA binding, while RRM3 is
responsible for protein-protein interactions. The
family also includes Splicing factor U2AF 50 kDa
subunit (dU2AF50), the Drosophila ortholog of U2AF65.
dU2AF50 functions as an essential pre-mRNA splicing
factor in flies. It associates with intronless mRNAs
and plays a significant and unexpected role in the
nuclear export of a large number of intronless mRNAs.
