C-terminal, alpha helical domain of the Glutathione S-transferase family; Glutathione S-transferase (GST) family, C-terminal alpha helical domain; a large, diverse group of cytosolic dimeric proteins involved in cellular detoxification by catalyzing the conjugation of glutathione (GSH) with a wide range of endogenous and xenobiotic alkylating agents, including carcinogens, therapeutic drugs, environmental toxins and products of oxidative stress. In addition, GSTs also show GSH peroxidase activity and are involved in the synthesis of prostaglandins and leukotrienes. This family, also referred to as soluble GSTs, is the largest family of GSH transferases and is only distantly related to the mitochondrial GSTs (GSTK). Soluble GSTs bear no structural similarity to microsomal GSTs (MAPEG family) and display additional activities unique to their group, such as catalyzing thiolysis, reduction and isomerization of certain compounds. The GST fold contains an N-terminal thioredoxin-fold domain and a C-terminal alpha helical domain, with an active site located in a cleft between the two domains. GSH binds to the N-terminal domain while the hydrophobic substrate occupies a pocket in the C-terminal domain. Based on sequence similarity, different classes of GSTs have been identified, which display varying tissue distribution, substrate specificities and additional specific activities. In humans, GSTs display polymorphisms which may influence individual susceptibility to diseases such as cancer, arthritis, allergy and sclerosis. Some GST family members with non-GST functions include glutaredoxin 2, the CLIC subfamily of anion channels, prion protein Ure2p, crystallins, metaxins, stringent starvation protein A, and aminoacyl-tRNA synthetases.

Glutathione S-transferase C-terminal-like, alpha helical domain of Aminoacyl tRNA synthetase complex-Interacting Multifunctional Protein 3; Glutathione S-transferase (GST) C-terminal domain family, Aminoacyl tRNA synthetase complex-Interacting Multifunctional Protein (AIMP) 3 subfamily; AIMPs are non-enzymatic cofactors that play critical roles in the assembly and formation of a macromolecular multi-tRNA synthetase protein complex that functions as a molecular hub to coordinate protein synthesis. There are three AIMPs, named AIMP1-3, which play diverse regulatory roles. AIMP3, also called p18 or eukaryotic translation elongation factor 1 epsilon-1 (EEF1E1), contains a C-terminal domain with similarity to the C-terminal alpha helical domain of GSTs. It specifically interacts with methionyl-tRNA synthetase (MetRS) and is translocated to the nucleus during DNA synthesis or in response to DNA damage and oncogenic stress. In the nucleus, it interacts with ATM and ATR, which are upstream kinase regulators of p53. It appears to work against DNA damage in cooperation with AIMP2, and similar to AIMP2, AIMP3 is also a haploinsufficient tumor suppressor. AIMP3 transgenic mice have shorter lifespans than wild-type mice and they show characteristics of progeria, suggesting that AIMP3 may also be involved in cellular and organismal aging.

Glutathione S-transferase C-terminal-like, alpha helical domain of various Aminoacyl-tRNA synthetases and similar domains; Glutathione S-transferase (GST) C-terminal domain family, Aminoacyl-tRNA synthetase (AaRS)-like subfamily; This model characterizes the GST_C-like domain found in the N-terminal region of some eukaryotic AaRSs, as well as similar domains found in proteins involved in protein synthesis including Aminoacyl tRNA synthetase complex-Interacting Multifunctional Protein 2 (AIMP2), AIMP3, and eukaryotic translation Elongation Factor 1 beta (eEF1b). AaRSs comprise a family of enzymes that catalyze the coupling of amino acids with their matching tRNAs. This involves the formation of an aminoacyl adenylate using ATP, followed by the transfer of the activated amino acid to the 3'-adenosine moiety of the tRNA. AaRSs may also be involved in translational and transcriptional regulation, as well as in tRNA processing. AaRSs in this subfamily include GluRS from lower eukaryotes, as well as GluProRS, MetRS, and CysRS from higher eukaryotes. AIMPs are non-enzymatic cofactors that play critical roles in the assembly and formation of a macromolecular multi-tRNA synthetase protein complex found in higher eukaryotes. The GST_C-like domain is involved in protein-protein interactions, mediating the formation of aaRS complexes such as the MetRS-Arc1p-GluRS ternary complex in lower eukaryotes and the multi-aaRS complex in higher eukaryotes, that act as molecular hubs for protein synthesis. AaRSs from prokaryotes, which are active as dimers, do not contain this GST_C-like domain. Pssm-ID: 198322 [Multi-domain] Cd Length: 82 Bit Score: 61.17 E-value: 1.79e-13

67-127 | 1.77e-05 | |||
Glutathione S-transferase C-terminal-like, alpha helical domain of the Gamma subunit of Elongation Factor 1B and similar proteins; Glutathione S-transferase (GST) C-terminal domain family, Gamma subunit of Elongation Factor 1B (EF1Bgamma) subfamily; EF1Bgamma is part of the eukaryotic translation elongation factor-1 (EF1) complex which plays a central role in the elongation cycle during protein biosynthesis. EF1 consists of two functionally distinct units, EF1A and EF1B. EF1A catalyzes the GTP-dependent binding of aminoacyl-tRNA to the ribosomal A site concomitant with the hydrolysis of GTP. The resulting inactive EF1A:GDP complex is recycled to the active GTP form by the guanine-nucleotide exchange factor EF1B, a complex composed of at least two subunits, alpha and gamma. Metazoan EFB1 contain a third subunit, beta. The EF1B gamma subunit contains a GST fold consisting of an N-terminal thioredoxin-fold domain and a C-terminal alpha helical domain. The GST-like domain of EF1Bgamma is believed to mediate the dimerization of the EF1 complex, which in yeast is a dimer of the heterotrimer EF1A:EF1Balpha:EF1Bgamma. In addition to its role in protein biosynthesis, EF1Bgamma may also display other functions. The recombinant rice protein has been shown to possess GSH conjugating activity. The yeast EF1Bgamma binds to membranes in a calcium dependent manner and is also part of a complex that binds to the msrA (methionine sulfoxide reductase) promoter suggesting a function in the regulation of its gene expression. Also included in this subfamily is the GST_C-like domain at the N-terminus of human valyl-tRNA synthetase (ValRS) and its homologs. Metazoan ValRS forms a stable complex with Elongation Factor-1H (EF-1H), and together, they catalyze consecutive steps in protein biosynthesis, tRNA aminoacylation and its transfer to EF.

Glutathione S-transferase C-terminal-like, alpha helical domain of the Aminoacyl tRNA synthetase cofactor 1 and similar proteins; Glutathione S-transferase (GST) C-terminal domain family, Aminoacyl tRNA synthetase cofactor 1 (Arc1p)-like subfamily; Arc1p, also called GU4 nucleic binding protein 1 (G4p1) or p42, is a tRNA-aminoacylation and nuclear-export cofactor. It contains a domain in the N-terminal region with similarity to the C-terminal alpha helical domain of GSTs. This domain mediates the association of the aminoacyl tRNA synthetases (aaRSs), MetRS and GluRS, in yeast to form a stable stoichiometric ternany complex. The GST_C-like domain of Arc1p is a protein-protein interaction domain containing two binding sites which enable it to bind the two aaRSs simultaneously and independently. The MetRS-Arc1p-GluRS complex selectively recruits and aminoacylates its cognate tRNAs without additional cofactors. Arc1p also plays a role in the transport of tRNA from the nucleus to the cytoplasm. It may also control the subcellular distribution of GluRS in the cytoplasm, nucleoplasm, and the mitochondrial matrix. Pssm-ID: 198337 [Multi-domain] Cd Length: 100 Bit Score: 38.89 E-value: 9.54e-05

There are three AIMPs, named AIMP1-3, which play diverse regulatory roles. AIMP2, also called p38 or JTV-1, contains a C-terminal domain with similarity to the C-terminal alpha helical domain of GSTs. It plays an important role in the control of cell fate via antiproliferative (by enhancing the TGF-beta signal) and proapoptotic (activation of p53 and TNF-alpha) activities. Its roles in the control of cell proliferation and death suggest that it is a potent tumor suppressor. AIMP2 heterozygous mice with lower than normal expression of AIMP2 show high susceptibility to tumorigenesis. AIMP2 is also a substrate of Parkin, an E3 ubiquitin ligase that is involved in the ubiquitylation and proteasomal degradation of its substrates. Mutations in the Parkin gene is found in 50% of patients with autosomal-recessive early-onset parkinsonism. The accumulation of AIMP2, due to impaired Parkin function, may play a role in the pathogenesis of Parkinson's disease. Pssm-ID: 198309 [Multi-domain] Cd Length: 96 Bit Score: 33.64 E-value: 8.58e-03
