Protein Kinases, catalytic domain; The protein kinase superfamily is mainly composed of the catalytic domains of serine/threonine-specific and tyrosine-specific protein kinases. It also includes RIO kinases, which are atypical serine protein kinases, aminoglycoside phosphotransferases, and choline kinases. These proteins catalyze the transfer of the gamma-phosphoryl group from ATP to hydroxyl groups in specific substrates such as serine, threonine, or tyrosine residues of proteins.

286-454 4.21e-12

Catalytic domain of Protein Kinases; PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine or tyrosine residues on protein substrates. PKs make up a large family of serine/threonine kinases (STKs), protein tyrosine kinases (PTKs), and dual-specificity PKs that phosphorylate both serine/threonine and tyrosine residues of target proteins. Majority of protein phosphorylation occurs on serine residues while only 1% occurs on tyrosine residues. Protein phosphorylation is a mechanism by which a wide variety of cellular proteins, such as enzymes and membrane channels, are reversibly regulated in response to certain stimuli. PKs often function as components of signal transduction pathways in which one kinase activates a second kinase, which in turn, may act on other kinases; this sequential action transmits a signal from the cell surface to target proteins, which results in cellular responses. The PK family is one of the largest known protein families with more than 100 homologous yeast enzymes and more than 500 human proteins. A fraction of PK family members are pseudokinases that lack crucial residues for catalytic activity. The mutiplicity of kinases allows for specific regulation according to substrate, tissue distribution, and cellular localization. PKs regulate many cellular processes including proliferation, division, differentiation, motility, survival, metabolism, cell-cycle progression, cytoskeletal rearrangement, immunity, and neuronal functions. Many kinases are implicated in the development of various human diseases including different types of cancer. The PK family is part of a larger superfamily that includes the catalytic domains of RIO kinases, aminoglycoside phosphotransferase, choline kinase, phosphoinositide 3-kinase (PI3K), and actin-fragmin kinase.

328-466 1.04e-08

Pseudokinase domain, repeat 1, of eukaryotic translation Initiation Factor 2-Alpha Kinase 4 or General Control Non-derepressible-2; The pseudokinase domain shows similarity to protein kinases but lacks crucial residues for catalytic activity. EIF2AKs phosphorylate the alpha subunit of eIF-2, resulting in the overall downregulation of protein synthesis. eIF-2 phosphorylation is induced in response to cellular stresses including virus infection, heat shock, nutrient deficiency, and the accummulation of unfolded proteins, among others. There are four distinct kinases that phosphorylate eIF-2 and control protein synthesis under different stress conditions: GCN2, protein kinase regulated by RNA (PKR), heme-regulated inhibitor kinase (HRI), and PKR-like endoplasmic reticulum kinase (PERK). GCN2 is activated by amino acid or serum starvation and UV irradiation. It induces GCN4, a transcriptional activator of amino acid biosynthetic genes, leading to increased production of amino acids under amino acid-deficient conditions. In serum-starved cells, GCN2 activation induces translation of the stress-responsive transcription factor ATF4, while under UV stress, GCN2 triggers transcriptional rescue via NF-kappaB signaling. GCN2 contains an N-terminal RWD, a degenerate kinase-like (repeat 1), the catalytic kinase (repeat 2), a histidyl-tRNA synthetase (HisRS)-like, and a C-terminal ribosome-binding and dimerization (RB/DD) domains. The degenerate pseudokinase domain of GCN2 may function as a regulatory domain. The GCN2 subfamily is part of a larger superfamily that includes the catalytic domains of serine/threonine kinases, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

295-500 1.12e-08

Catalytic domain of bacterial Serine/Threonine kinases, PknB and similar proteins; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily includes many bacterial eukaryotic-type STKs including Staphylococcus aureus PknB (also called PrkC or Stk1), Bacillus subtilis PrkC, and Mycobacterium tuberculosis Pkn proteins (PknB, PknD, PknE, PknF, PknL, and PknH), among others. S. aureus PknB is the only eukaryotic-type STK present in this species, although many microorganisms encode for several such proteins. It is important for the survival and pathogenesis of S. aureus as it is involved in the regulation of purine and pyrimidine biosynthesis, cell wall metabolism, autolysis, virulence, and antibiotic resistance. M. tuberculosis PknB is essential for growth and it acts on diverse substrates including proteins involved in peptidoglycan synthesis, cell division, transcription, stress responses, and metabolic regulation. B. subtilis PrkC is located at the inner membrane of endospores and functions to trigger spore germination. Bacterial STKs in this subfamily show varied domain architectures. The well-characterized members such as S. aureus and M. tuberculosis PknB, and B. subtilis PrkC, contain an N-terminal cytosolic kinase domain, a transmembrane (TM) segment, and mutliple C-terminal extracellular PASTA domains. The PknB subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

287-452 4.11e-07

Catalytic domain of the Serine/Threonine kinase, With No Lysine (WNK) kinase; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. WNKs comprise a subfamily of STKs with an unusual placement of a catalytic lysine relative to all other protein kinases. They are critical in regulating ion balance and are thus, important components in the control of blood pressure. They are also involved in cell signaling, survival, proliferation, and organ development. WNKs are activated by hyperosmotic or low-chloride hypotonic stress and they function upstream of SPAK and OSR1 kinases, which regulate the activity of cation-chloride cotransporters through direct interaction and phosphorylation. There are four vertebrate WNKs which show varying expression patterns. WNK1 and WNK2 are widely expressed while WNK3 and WNK4 show a more restricted expression pattern. Because mutations in human WNK1 and WNK4 cause PseudoHypoAldosteronism type II (PHAII), characterized by hypertension (due to increased sodium reabsorption) and hyperkalemia (due to impaired renal potassium secretion), there are more studies conducted on these two proteins, compared to WNK2 and WNK3. The WNK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

299-453 9.38e-06

Catalytic domain of the Serine/Threonine kinases, Interleukin-1 Receptor Associated Kinases and related STKs; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. IRAKs are involved in Toll-like receptor (TLR) and interleukin-1 (IL-1) signalling pathways, and are thus critical in regulating innate immune responses and inflammation. Some IRAKs may also play roles in T- and B-cell signaling, and adaptive immunity. Vertebrates contain four IRAKs (IRAK-1, -2, -3 (or -M), and -4) that display distinct functions and patterns of expression and subcellular distribution, and can differentially mediate TLR signaling. IRAK-1, -2, and -4 are ubiquitously expressed and are active kinases, while IRAK-M is only induced in monocytes and macrophages and is an inactive kinase. Variations in IRAK genes are linked to diverse diseases including infection, sepsis, cancer, and autoimmune diseases. IRAKs contain an N-terminal Death domain (DD), a proST region (rich in serines, prolines, and threonines), a central kinase domain (a pseudokinase domain in the case of IRAK3), and a C-terminal domain; IRAK-4 lacks the C-terminal domain. This subfamily includes plant receptor-like kinases (RLKs) including Arabidopsis thaliana BAK1 and CLAVATA1 (CLV1). BAK1 functions in BR (brassinosteroid)-regulated plant development and in pathways involved in plant resistance to pathogen infection and herbivore attack. CLV1, directly binds small signaling peptides, CLAVATA3 (CLV3) and CLAVATA3/EMBRYO SURROUNDING REGI0N (CLE), to restrict stem cell proliferation: the CLV3-CLV1-WUS (WUSCHEL) module influences stem cell maintenance in the shoot apical meristem, and the CLE40 (CLAVATA3/EMBRYO SURROUNDING REGION40) -ACR4 (CRINKLY4) -CLV1- WOX5 (WUSCHEL-RELATED HOMEOBOX5) module at the root apical meristem. The IRAK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

Catalytic domain of Mitogen-Activated Protein Kinase (MAPK) Kinase Kinase-like Serine/Threonine kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. This subfamily is composed mainly of MAP3Ks and similar proteins, including TGF-beta Activated Kinase-1 (TAK1, also called MAP3K7), MAP3K12, MAP3K13, Mixed lineage kinase (MLK), MLK-Like mitogen-activated protein Triple Kinase (MLTK), and Raf (Rapidly Accelerated Fibrosarcoma) kinases. MAP3Ks (MKKKs or MAPKKKs) phosphorylate and activate MAPK kinases (MAPKKs or MKKs or MAP2Ks), which in turn phosphorylate and activate MAPKs during signaling cascades that are important in mediating cellular responses to extracellular signals. Also included in this subfamily is the pseudokinase Kinase Suppressor of Ras (KSR), which is a scaffold protein that functions downstream of Ras and upstream of Raf in the Extracellular signal-Regulated Kinase (ERK) pathway.

Catalytic domain of the Dual-specificity protein kinase, Lymphokine-activated killer T-cell-originated protein kinase; Dual-specificity PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine as well as tyrosine residues on protein substrates. TOPK, also called PDZ-binding kinase (PBK), is activated at the early stage of mitosis and plays a critical role in cytokinesis. It partly functions as a mitogen-activated protein kinase (MAPK) kinase and is capable of phosphorylating p38, JNK1, and ERK2. TOPK also plays a role in DNA damage sensing and repair through its phosphorylation of histone H2AX. It contributes to cancer development and progression by downregulating the function of tumor suppressor p53 and reducing cell-cycle regulatory proteins. TOPK is found highly expressed in breast and skin cancer cells. The TOPK subfamily is part of a larger superfamily that includes the catalytic domains of other protein kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

299-452 1.58e-03

Catalytic domain of the Serine/Threonine protein kinase, With No Lysine (WNK) 4; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. WNK4 shows a restricted expression pattern and is usually found in epithelial cells. It is expressed in nephrons and in extrarenal tissues including intestine, eye, mammary glands, and prostate. WNK4 regulates a variety of ion transport proteins including apical or basolateral ion transporters, ion channels in the transcellular pathway, and claudins in the paracellular pathway. Mutations in WNK4 cause PseudoHypoAldosteronism type II (PHAII), characterized by hypertension and hyperkalemia. WNK4 inhibits the activity of the thiazide-sensitive Na-Cl cotransporter (NCC), which is responsible for about 15% of NaCl reabsorption in the kidney. It also inhibits the renal outer medullary potassium channel (ROMK) and decreases its surface expression. Hypertension and hyperkalemia in PHAII patients with WNK4 mutations may be partly due to increased NaCl reabsorption through NCC and impaired renal potassium secretion by ROMK, respectively. The WNK4 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

295-412 3.24e-03

Catalytic domain of the Serine/Threonine Kinase, novel (nua) kinase family NUAK; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. NUAK proteins are classified as AMP-activated protein kinase (AMPK)-related kinases, which like AMPK are activated by the major tumor suppressor LKB1. Vertebrates contain two NUAK proteins, called NUAK1 and NUAK2. NUAK1, also called ARK5 (AMPK-related protein kinase 5), regulates cell proliferation and displays tumor suppression through direct interaction and phosphorylation of p53. It is also involved in cell senescence and motility. High NUAK1 expression is associated with invasiveness of nonsmall cell lung cancer (NSCLC) and breast cancer cells. NUAK2, also called SNARK (Sucrose, non-fermenting 1/AMP-activated protein kinase-related kinase), is involved in energy metabolism. It is activated by hyperosmotic stress, DNA damage, and nutrients such as glucose and glutamine. NUAK2-knockout mice develop obesity, altered serum lipid profiles, hyperinsulinaemia, hyperglycaemia, and impaired glucose tolerance. The NUAK subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

324-484 6.52e-03

Catalytic domain of Dual-specificity tYrosine-phosphorylated and -Regulated Kinase-like protein kinases; Dual-specificity PKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine (S/T) as well as tyrosine residues on protein substrates. This subfamily is composed of the dual-specificity DYRKs and YAK1, as well as the S/T kinases (STKs), HIPKs. DYRKs and YAK1 autophosphorylate themselves on tyrosine residues and phosphorylate their substrates exclusively on S/T residues. Proteins in this subfamily play important roles in cell proliferation, differentiation, survival, growth, and development. The DYRK-like subfamily is part of a larger superfamily that includes the catalytic domains of other STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

300-452 7.05e-03

Catalytic domain of With No Lysine (WNK) 2-like Serine/Threonine kinases; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. WNK2 is widely expressed and has been shown to be epigenetically silenced in gliomas. It inhibits cell growth by acting as a negative regulator of MEK1-ERK1/2 signaling. WNK2 modulates growth factor-induced cancer cell proliferation, suggesting that it may be a tumor suppressor gene. WNKs comprise a subfamily of STKs with an unusual placement of the catalytic lysine relative to all other protein kinases. They are critical in regulating ion balance and are thus, important components in the control of blood pressure. The WNK2-like subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.

296-386 7.91e-03

Catalytic domain of the Serine/Threonine kinase, Unc-51-like kinase 3; STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The ATG1/ULK complex is conserved from yeast to humans and it plays a critical role in the initiation of autophagy, the intracellular system that leads to the lysosomal degradation of cellular components and their recycling into basic metabolic units. ULK3 mRNA is up-regulated in fibroblasts after Ras-induced senescence, and its overexpression induces both autophagy and senescence in a fibroblast cell line. ULK3, through its kinase activity, positively regulates Gli proteins, mediators of the Sonic hedgehog (Shh) signaling pathway that is implicated in tissue homeostasis maintenance and neurogenesis. It is inhibited by binding to Suppressor of Fused (Sufu). The ULK3 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase.
