Label Id Description
GRB2 Adaptor Protein D051380 [A signal transducing adaptor protein that links extracellular signals to the MAP KINASE SIGNALING SYSTEM. Grb2 associates with activated EPIDERMAL GROWTH FACTOR RECEPTOR and PLATELET-DERIVED GROWTH FACTOR RECEPTORS via its SH2 DOMAIN. It also binds to and translocates the SON OF SEVENLESS PROTEINS through its SH3 DOMAINS to activate PROTO-ONCOGENE PROTEIN P21(RAS). , Grb3-3 is a natural isoform of GRB2 PROTEIN with a deletion in the SH2 DOMAIN. It acts as a dominant negative protein over GRB2, suppressing proliferative signals. It has also been implicated in APOPTOSIS. ]
GRB7 Adaptor Protein D051382 [A SH2 DOMAIN-containing protein that mediates SIGNAL TRANSDUCTION pathways from multiple CELL SURFACE RECEPTORS, including the EPHB1 RECEPTOR. It interacts with FOCAL ADHESION KINASE and is involved in CELL MIGRATION. ]
GTP Cyclohydrolase D006136 [(GTP cyclohydrolase I) or GTP 7,8-8,9-dihydrolase (pyrophosphate-forming) (GTP cyclohydrolase II). An enzyme group that hydrolyzes the imidazole ring of GTP, releasing carbon-8 as formate. Two C-N bonds are hydrolyzed and the pentase unit is isomerized. This is the first step in the synthesis of folic acid from GTP. EC 3.5.4.16 (GTP cyclohydrolase I) and EC 3.5.4.25 (GTP cyclohydrolase II). ]
GTP Phosphohydrolase Activators D020549 [Agents and factors that activate GTP phosphohydrolase activity. ]
GTP Phosphohydrolase-Linked Elongation Factors D020963 [Factors that utilize energy from the hydrolysis of GTP to GDP for peptide chain elongation. EC 3.6.1.-. ]
GTP Phosphohydrolases D020558 [Enzymes that hydrolyze GTP to GDP. EC 3.6.1.-. ]
GTP Pyrophosphokinase D001277 [An enzyme that catalyzes reversibly the transfer of a pyrophosphate group from ATP to the 3'-OH group of GDP or GTP with the formation of guanosine 3'-diphosphate 5'-diphosphate or guanosine 3'-diphosphate 5'-triphosphate and AMP. The enzyme, also called stringent factor, is located in the relA gene in stringent strains of bacteria. The above synthesis is induced by mRNA and uncharged tRNA which is bound to the aminoacyl-t-RNA binding site of the ribosome by a codon-specific association. EC 2.7.6.5. ]
GTP-Binding Protein Regulators D020555 [Proteins that regulate the signaling activity of GTP-BINDING PROTEINS. They are divided into three categories depending upon whether they stimulate GTPase activity (GTPASE-ACTIVATING PROTEINS), inhibit release of GDP; (GUANINE NUCLEOTIDE DISSOCIATION INHIBITORS); or exchange GTP for GDP; (GUANINE NUCLEOTIDE EXCHANGE FACTORS). ]
GTP-Binding Protein alpha Subunit, Gi2 D051960 [A PERTUSSIS TOXIN-sensitive GTP-binding protein alpha subunit. It couples with a variety of CELL SURFACE RECEPTORS, has been implicated in INTERLEUKIN-12 production, and may play a role in INFLAMMATORY BOWEL DISEASES. ]
GTP-Binding Protein alpha Subunits D044385 [The GTPase-containing subunits of heterotrimeric GTP-binding proteins. When dissociated from the heterotrimeric complex these subunits interact with a variety of second messenger systems. Hydrolysis of GTP by the inherent GTPase activity of the subunit causes it to revert to its inactive (heterotrimeric) form. The GTP-Binding protein alpha subunits are grouped into families according to the type of action they have on second messenger systems. ]
GTP-Binding Protein alpha Subunits, G12-G13 D044365 [A ubiquitously expressed family of heterotrimeric GTP-binding protein alpha subunits that signal through interactions with a variety of second messengers as GTPASE-ACTIVATING PROTEINS; GUANINE NUCLEOTIDE EXCHANGE FACTORS; and HEAT SHOCK PROTEINS. The G12-G13 part of the name is also spelled G12/G13. ]
GTP-Binding Protein alpha Subunits, Gi-Go D019206 [A family of heterotrimeric GTP-binding protein alpha subunits that were originally identified by their ability to inhibit ADENYLYL CYCLASES. Members of this family can couple to beta and gamma G-protein subunits that activate POTASSIUM CHANNELS. The Gi-Go part of the name is also spelled Gi/Go. ]
GTP-Binding Protein alpha Subunits, Gq-G11 D043802 [A family of heterotrimeric GTP-binding protein alpha subunits that activate TYPE C PHOSPHOLIPASES dependent signaling pathways. The Gq-G11 part of the name is also spelled Gq/G11. ]
GTP-Binding Protein alpha Subunits, Gs D019205 [A family of heterotrimeric GTP-binding protein alpha subunits that activate ADENYLYL CYCLASES. ]
GTP-Binding Protein beta Subunits D044387 [Heterotrimeric GTP-binding protein subunits that tightly associate with GTP-BINDING PROTEIN GAMMA SUBUNITS. A dimer of beta and gamma subunits is formed when the GTP-BINDING PROTEIN ALPHA SUBUNIT dissociates from the GTP-binding protein heterotrimeric complex. The beta-gamma dimer can play an important role in signal transduction by interacting with a variety of second messengers. ]
GTP-Binding Protein gamma Subunits D044388 [Heterotrimeric GTP-binding protein subunits that tightly associate with GTP-BINDING PROTEIN BETA SUBUNITS. A dimer of beta and gamma subunits is formed when the GTP-BINDING PROTEIN ALPHA SUBUNIT dissociates from the GTP-binding protein heterotrimeric complex. The beta-gamma dimer can play an important role in signal transduction by interacting with a variety of second messengers. ]
GTP-Binding Proteins D019204 [Regulatory proteins that act as molecular switches. They control a wide range of biological processes including: receptor signaling, intracellular signal transduction pathways, and protein synthesis. Their activity is regulated by factors that control their ability to bind to and hydrolyze GTP to GDP. EC 3.6.1.-. ]

Gabapentin D000077206 [A cyclohexane-gamma-aminobutyric acid derivative that is used for the treatment of PARTIAL SEIZURES; NEURALGIA; and RESTLESS LEGS SYNDROME. ]
Gabexate D016670 [A serine proteinase inhibitor used therapeutically in the treatment of pancreatitis, disseminated intravascular coagulation (DIC), and as a regional anticoagulant for hemodialysis.
