>gnl|CDD|107230 cd06475, ACD_HspB1_like, Alpha crystallin domain (ACD) found in
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.

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.

mammalian small heat shock protein (sHsp) HspB2/heat
shock 27kDa protein 2 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. HspB2 is preferentially and constitutively
expressed in skeletal muscle and heart. HspB2 shows
homooligomeric activity and forms aggregates in muscle
cytosol. Although its expression is not induced by heat
shock, it redistributes to the insoluble fraction in
response to heat shock. In the mouse heart, HspB2 plays
a role in maintaining energetic balance, by protecting
cardiac energetics during ischemia/reperfusion, and
allowing for increased work during acute inotropic
challenge. hHspB2 [previously also known as myotonic
dystrophy protein kinase (DMPK) binding protein (MKBP)]
is selectively up-regulated in skeletal muscles from
myotonic dystrophy patients. The ACD of hHspB2 binds the
DMPK kinase domain. In vitro, hHspB2 enhances the kinase
activity of DMPK and confers thermoresistance. The
hHspB2 gene lies less than 1kb from the 5 prime end of
the related alphaB (HspB4)-crystallin gene, with the
opposite transcription direction. These two genes may
share regulatory elements for their expression.

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.

>gnl|CDD|212742 cd11808, SH3_Alpha_Spectrin, Src homology 3 domain of Alpha
Spectrin. Spectrin is a major structural component of
the red blood cell membrane skeleton and is important in
erythropoiesis and membrane biogenesis. It is a
flexible, rope-like molecule composed of two subunits,
alpha and beta, which consist of many spectrin-type
repeats. Alpha and beta spectrin associate to form
heterodimers and tetramers; spectrin tetramer formation
is critical for red cell shape and deformability.
Defects in alpha spectrin have been associated with
inherited hemolytic anemias including hereditary
spherocytosis (HSp), hereditary elliptocytosis (HE), and
hereditary pyropoikilocytosis (HPP). Alpha spectrin
contains a middle SH3 domain and a C-terminal EF-hand
binding motif in addition to multiple spectrin repeats.
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.

polyadenylation element-binding protein CPEB-2, CPEB-3,
CPEB-4 and similar protiens. This subgroup corresponds
to the RRM1 of the paralog proteins CPEB-2, CPEB-3 and
CPEB-4, all well-conserved in both, vertebrates and
invertebrates. Due to the high sequence similarity,
members in this family may share similar expression
patterns and functions. CPEB-2 is an RNA-binding protein
that is abundantly expressed in testis and localized in
cytoplasm in transfected HeLa cells. It preferentially
binds to poly(U) RNA oligomers and may regulate the
translation of stored mRNAs during spermiogenesis.
Moreover, CPEB-2 impedes target RNA translation at
elongation; it directly interacts with the elongation
factor, eEF2, to reduce eEF2/ribosome-activated GTP
hydrolysis in vitro and inhibit peptide elongation of
CPEB2-bound RNA in vivo. CPEB-3 is a sequence-specific
translational regulatory protein that regulates
translation in a polyadenylation-independent manner. It
functions as a translational repressor that governs the
synthesis of the AMPA receptor GluR2 through binding
GluR2 mRNA. It also represses translation of a reporter
RNA in transfected neurons and stimulates translation in
response to NMDA. CPEB-4 is an RNA-binding protein that
mediates meiotic mRNA cytoplasmic polyadenylation and
translation. It is essential for neuron survival and
present on the endoplasmic reticulum (ER). It is
accumulated in the nucleus upon ischemia or the
depletion of ER calcium. CPEB-4 is overexpressed in a
large variety of tumors and is associated with many
mRNAs in cancer cells. All family members contain an
N-terminal unstructured region, two RNA recognition
motifs (RRMs), also termed RBDs (RNA binding domains) or
RNPs (ribonucleoprotein domains), and a Zn-finger motif.
In addition, they do have conserved nuclear export
signals that are not present in CPEB-1. .

NifN subunit of the NifEN complex: NifN forms an
alpha2beta2 tetramer with NifE. NifN and nifE are
structurally homologous to nitrogenase MoFe protein beta
and alpha subunits respectively. NifEN participates in
the synthesis of the iron-molybdenum cofactor (FeMoco)
of the MoFe protein. NifB-co (an iron and sulfur
containing precursor of the FeMoco) from NifB is
transferred to the NifEN complex where it is further
processed to FeMoco. The nifEN bound precursor of FeMoco
has been identified as a molybdenum-free, iron- and
sulfur- containing analog of FeMoco. It has been
suggested that this nifEN bound precursor also acts as a
cofactor precursor in nitrogenase systems which require
a cofactor other than FeMoco: i.e. iron-vanadium
cofactor (FeVco) or iron only cofactor (FeFeco).
