>gnl|CDD|119432 cd05172, PIKKc_DNA-PK, DNA-dependent protein kinase (DNA-PK),
catalytic domain; The DNA-PK catalytic domain subfamily
is part of a larger superfamily that includes the
catalytic domains of other kinases such as the typical
serine/threonine/tyrosine protein kinases (PKs),
aminoglycoside phosphotransferase, choline kinase, and
RIO kinases. DNA-PK is a member of the phosphoinositide
3-kinase-related protein kinase (PIKK) subfamily. PIKKs
have intrinsic serine/threonine kinase activity and are
distinguished from other PKs by their unique catalytic
domain, similar to that of lipid PI3K, and their large
molecular weight (240-470 kDa). DNA-PK is comprised of a
regulatory subunit, containing the Ku70/80 subunit, and
a catalytic subunit, which contains a NUC194 domain of
unknown function, a FAT (FRAP, ATM and TRRAP) domain, a
catalytic domain, and a FATC domain at the C-terminus.
It is part of a multi-component system involved in
non-homologous end joining (NHEJ), a process of
repairing double strand breaks (DSBs) by joining
together two free DNA ends of little homology. DNA-PK
functions as a molecular sensor for DNA damage that
enhances the signal via phosphorylation of downstream
targets. It may also act as a protein scaffold that aids
the localization of DNA repair proteins to the site of
DNA damage. DNA-PK also plays a role in the maintenance
of telomeric stability and the prevention of chromosomal
end fusion.

Phosphoinositide 3-kinase isoforms participate in a
variety of processes, including cell motility, the Ras
pathway, vesicle trafficking and secretion, and
apoptosis. These homologues may be either lipid kinases
and/or protein kinases: the former phosphorylate the
3-position in the inositol ring of inositol
phospholipids. The ataxia telangiectesia-mutated gene
produced, the targets of rapamycin (TOR) and the
DNA-dependent kinase have not been found to possess
lipid kinase activity. Some of this family possess PI-4
kinase activities.

a critical role in the mRNA surveillance mechanism known
as non-sense mediated mRNA decay (NMD). NMD protects the
cells from the accumulation of aberrant mRNAs with
premature termination codons (PTCs) generated by genome
mutations and by errors during transcription and
splicing. SMG-1 phosphorylates Upf1, another central
component of NMD, at the C-terminus upon recognition of
PTCs. The phosphorylation/dephosphorylation cycle of
Upf1 is essential for promoting NMD.

Ras binding domain, a lipid binding C2 domain, a PI3K
homology domain of unknown function, and a C-terminal
ATP-binding cataytic domain. They associate with a
regulatory subunit of the p85 family and are activated
by tyrosine kinase receptors. PI3Kdelta is mainly
expressed in immune cells and plays an important role in
cellular and humoral immunity. It plays a major role in
antigen receptor signaling in B-cells, T-cells, and mast
cells. It regulates the differentiation of peripheral
helper T-cells and controls the development and function
of regulatory T-cells.

>gnl|CDD|119427 cd05167, PI4Kc_III_alpha, Phosphoinositide 4-kinase (PI4K), Type
III, alpha isoform, catalytic domain; The PI4K catalytic
domain family is part of a larger superfamily that
includes the catalytic domains of other kinases such as
the typical serine/threonine/tyrosine protein kinases
(PKs), aminoglycoside phosphotransferase, choline
kinase, and RIO kinases. PI4Ks catalyze the transfer of
the gamma-phosphoryl group from ATP to the 4-hydroxyl of
the inositol ring of D-myo-phosphatidylinositol (PtdIns)
to generate PtdIns(4)P, the major precursor in the
synthesis of other phosphoinositides including
PtdIns(4,5)P2, PtdIns(3,4)P2, and PtdIns(3,4,5)P3. Two
isoforms of type III PI4K, alpha and beta, exist in most
eukaryotes. PI4KIIIalpha is a 220 kDa protein found in
the plasma membrane and the endoplasmic reticulum (ER).
The role of PI4KIIIalpha in the ER remains unclear. In
the plasma membrane, it provides PtdIns(4)P, which is
then converted by PI5Ks to PtdIns(4,5)P2, an important
signaling molecule. Vertebrate PI4KIIIalpha is also part
of a signaling complex associated with P2X7 ion
channels. The yeast homolog, Stt4p, is also important in
regulating the conversion of phosphatidylserine to
phosphatidylethanolamine at the ER and Golgi interface.
Mammalian PI4KIIIalpha is highly expressed in the
nervous system.

>gnl|CDD|173958 cd08199, EEVS, 2-epi-5-epi-valiolone synthase (EEVS).
2-epi-5-epi-valiolone synthases catalyze the cyclization
of sedoheptulose 7-phosphate to 2-epi-5-epi-valiolone in
the biosynthesis of C(7)N-aminocyclitol-containing
products. The cyclization product, 2-epi-5-epi-valiolone
((2S,3S,4S,5R)-5-(hydroxymethyl)cyclohexanon-2,3,4,
5-tetrol), is a precursor of the valienamine moiety. The
valienamine unit is responsible for their biological
activities as various glycosidic hydrolases inhibitors.
Two important microbial secondary metabolites, i.e.,
validamycin and acarbose, are used in agricultural and
biomedical applications. Validamycine A is an antifungal
antibiotic which has a strong trehalase inhibitory
activity and has been used to control sheath blight
disease in rice caused by Rhizoctonia solani. Acarbose
is an alpha-glucosidase inhibitor used for the treatment
of type II insulin-independent diabetes. Salbostatin
produced by Streptomyces albus also belongs to this
family. It exhibits strong trehalase inhibitory
activity.
