Mutations in this gene are pleiotropic, but it appears that effects on cellular functions such as chromosome partition may be secondary to the effect on ribosome structure.

TGS (ThrRS, GTPase and SpoT) domain found in developmentally regulated GTP binding protein 1 (DRG-1); DRG-1 is a potassium-dependent GTPase that belongs to the DRG family GTP-binding proteins. It plays an important role in regulating cell growth. It functions as a potential oncogene in lung adenocarcinoma and promotes tumor progression via spindle checkpoint signaling regulation. It also plays an important role in melanoma cell growth and transformation, indicating a novel role in CD4(+) T cell-mediated immunotherapy in melanoma. In addition, DRG-1 is regulated by ZC3H15 (zinc finger CCCH-type containing 15, also known as Lerepo4), and displays a high temperature optimum of activity at 42C, suggesting the ability of being active under possible heat stress conditions. DRG-1 contains a domain of characteristic Obg-type G-motifs that may be the core of GTPase activity, as well as this C-terminal TGS (ThrRS, GTPase and SpoT) domain that has a predominantly beta-grasp ubiquitin-like fold and may be related to RNA binding.

TGS (ThrRS, GTPase and SpoT) domain found in developmentally regulated GTP binding protein 2 (DRG-2); DRG-2 is a member of the DRG family GTP-binding proteins. It has been implicated in cell growth, differentiation and death. DRG-2 plays a critical role in control of the cell cycle and apoptosis in Jurkat T cells. It regulates G2/M progression via the cyclin B1-Cdk1 complex. Moreover, DRG-2 is an endosomal protein and a key regulator of the small GTPase Rab5 deactivation and transferrin recycling. It enhances experimental autoimmune encephalomyelitis (EAE) by suppressing the development of TH17 cells. It is also associated with survival and cytoskeleton organization of osteoclasts under influence of macrophage colony-stimulating factor, and its overexpression leads to elevated bone resorptive activity of osteoclasts, resulting in bone loss. DRG-2 contains a domain of characteristic Obg-type G-motifs that may be the core of GTPase activity, as well as this C-terminal TGS (ThrRS, GTPase and SpoT) domain that has a predominantly beta-grasp ubiquitin-like fold and may be involved in RNA binding.

Obg-like family of GTPases consist of five subfamilies: Obg, DRG, YyaF/YchF, Ygr210, and NOG1; The Obg-like subfamily consists of five well-delimited, ancient subfamilies, namely Obg, DRG, YyaF/YchF, Ygr210, and NOG1. Four of these groups (Obg, DRG, YyaF/YchF, and Ygr210) are characterized by a distinct glycine-rich motif immediately following the Walker B motif (G3 box). Obg/CgtA is an essential gene that is involved in the initiation of sporulation and DNA replication in the bacteria Caulobacter and Bacillus, but its exact molecular role is unknown. Furthermore, several OBG family members possess a C-terminal RNA-binding domain, the TGS domain, which is also present in threonyl-tRNA synthetase and in bacterial guanosine polyphosphatase SpoT. Nog1 is a nucleolar protein that might function in ribosome assembly. The DRG and Nog1 subfamilies are ubiquitous in archaea and eukaryotes, the Ygr210 subfamily is present in archaea and fungi, and the Obg and YyaF/YchF subfamilies are ubiquitous in bacteria and eukaryotes. The Obg/Nog1 and DRG subfamilies appear to form one major branch of the Obg family and the Ygr210 and YchF subfamilies form another branch. No GEFs, GAPs, or GDIs for Obg have been identified.

The TGS domain is named after the various RNA-binding multidomain ThrRS, GTPase, and SpoT/RelA proteins in which this domain occurs. The TGS domain of Obg-like GTPases such as those present in DRG (developmentally regulated GTP-binding protein), and GTP-binding proteins Ygr210 and YchF has a beta-grasp ubiquitin-like fold, a common structure involved in protein-protein interactions.

Interestingly, TGS domain was detected also at the amino terminus of the uridine kinase from the spirochaete Treponema pallidum (but not any other organizm, including the related spirochaete Borrelia burgdorferi). TGS is a small domain that consists of ~50 amino acid residues and is predicted to possess a predominantly beta-sheet structure. There is no direct information on the functions of the TGS domain, but its presence in two types of regulatory proteins (the GTPases and guanosine polyphosphate phosphohydrolases/synthetases) suggests a ligand (most likely nucleotide)-binding, regulatory role.

Thus, defects in NOG1 can lead to defects in 60S biogenesis. The S. cerevisiae NOG1 gene is essential for cell viability, and mutations in the predicted G motifs abrogate function.

E. coli Ras-like protein (Era)-like GTPase; The Era (E. coli Ras-like protein)-like family includes several distinct subfamilies (TrmE/ThdF, FeoB, YihA (EngB), Era, and EngA/YfgK) that generally show sequence conservation in the region between the Walker A and B motifs (G1 and G3 box motifs), to the exclusion of other GTPases. TrmE is ubiquitous in bacteria and is a widespread mitochondrial protein in eukaryotes, but is absent from archaea. The yeast member of TrmE family, MSS1, is involved in mitochondrial translation; bacterial members are often present in translation-related operons. FeoB represents an unusual adaptation of GTPases for high-affinity iron (II) transport. YihA (EngB) family of GTPases is typified by the E. coli YihA, which is an essential protein involved in cell division control. Era is characterized by a distinct derivative of the KH domain (the pseudo-KH domain) which is located C-terminal to the GTPase domain. EngA and its orthologs are composed of two GTPase domains and, since the sequences of the two domains are more similar to each other than to other GTPases, it is likely that an ancient gene duplication, rather than a fusion of evolutionarily distinct GTPases, gave rise to this family.

Rat sarcoma (Ras)-like superfamily of small guanosine triphosphatases (GTPases); Ras-like GTPase superfamily. The Ras-like superfamily of small GTPases consists of several families with an extremely high degree of structural and functional similarity. The Ras superfamily is divided into at least four families in eukaryotes: the Ras, Rho, Rab, and Sar1/Arf families. This superfamily also includes proteins like the GTP translation factors, Era-like GTPases, and G-alpha chain of the heterotrimeric G proteins. Members of the Ras superfamily regulate a wide variety of cellular functions: the Ras family regulates gene expression, the Rho family regulates cytoskeletal reorganization and gene expression, the Rab and Sar1/Arf families regulate vesicle trafficking, and the Ran family regulates nucleocytoplasmic transport and microtubule organization. The GTP translation factor family regulates initiation, elongation, termination, and release in translation, and the Era-like GTPase family regulates cell division, sporulation, and DNA replication. Members of the Ras superfamily are identified by the GTP binding site, which is made up of five characteristic sequence motifs, and the switch I and switch II regions.

EngA2 GTPase contains the second domain of EngA; This EngA2 subfamily CD represents the second GTPase domain of EngA and its orthologs, which are composed of two adjacent GTPase domains. Since the sequences of the two domains are more similar to each other than to other GTPases, it is likely that an ancient gene duplication, rather than a fusion of evolutionarily distinct GTPases, gave rise to this family. Although the exact function of these proteins has not been elucidated, studies have revealed that the E. coli EngA homolog, Der, and Neisseria gonorrhoeae EngA are essential for cell viability. A recent report suggests that E. coli Der functions in ribosome assembly and stability. Pssm-ID: 206682 [Multi-domain] Cd Length: 174 Bit Score: 41.26 E-value: 2.74e-04

Circularly permuted YlqF GTPase; Proteins of the YlqF family contain all sequence motifs typical of the vast class of P-loop-containing GTPases, but show a circular permutation, with a G4-G1-G3 pattern of motifs as opposed to the regular G1-G3-G4 pattern seen in most GTPases. The YlqF subfamily is represented in all eukaryotes as well as a phylogenetically diverse array of bacteria (including gram-positive bacteria, proteobacteria, Synechocystis, Borrelia, and Thermotoga).

Methylmalonyl Co-A mutase-associated GTPase MeaB; Family members were previously thought to be ArgK proteins acting as ATPase enzymes and kinases. They are now believed to be methylmalonyl Co-A mutase-associated GTPase MeaB. Structural studies of MeaB and the human ortholog (methylmalonyl associated protein A) MMAA, reveal alpha-helical domains at the N- and C-termini as well as a Ras-like GTPase domain. Mutational analysis of MeaB, show prohibited growth in Methylobacterium due to the inability to convert methylmalonyl-CoA to succinyl-CoA caused by an inactive form of methylmalonyl-CoA mutatase (mcm). In humans, mutations in (MMAA) are associated with the fatal disease methylmalonyl aciduria. Pssm-ID: 281323 [Multi-domain] Cd Length: 272 Bit Score: 37.41 E-value: 9.94e-03
