rab4 GTP-Binding Proteins D020695 [A genetically related subfamily of RAB GTP-BINDING PROTEINS involved in recycling of proteins such as cell surface receptors from early endosomes to the cell surface. This enzyme was formerly listed as EC 3.6.1.47. ]
rab5 GTP-Binding Proteins D020696 [A genetically related subfamily of RAB GTP-BINDING PROTEINS involved in transport from the cell membrane to early endosomes. This enzyme was formerly listed as EC 3.6.1.47. ]
rac GTP-Binding Proteins D020744 [A sub-family of RHO GTP-BINDING PROTEINS that is involved in regulating the organization of cytoskeletal filaments. This enzyme was formerly listed as EC 3.6.1.47. ]
rac1 GTP-Binding Protein D020830 [A rac GTP-binding protein involved in regulating actin filaments at the plasma membrane. It controls the development of filopodia and lamellipodia in cells and thereby influences cellular motility and adhesion. It is also involved in activation of NADPH OXIDASES. This enzyme was formerly listed as EC 3.6.1.47. ]
raf Kinases D048490 [A family of closely-related serine-threonine kinases that were originally identified as the cellular homologs of the retrovirus-derived V-RAF KINASES. They are MAP kinase kinase kinases that play important roles in SIGNAL TRANSDUCTION. ]
ral GTP-Binding Proteins D020725 [Cannot add RN: EC 3.6.1.- , A family of ubiquitously expressed MONOMERIC GTP-BINDING PROTEINS that are involved in intracellular signal transduction. This enzyme was formerly listed as EC 3.6.1.47. ]
ral Guanine Nucleotide Exchange Factor D020726 [A guanine nucleotide exchange factor that stimulates the dissociation of GDP from RAL GTP-BINDING PROTEINS. It also has GDP exchange activity towards other MONOMERIC GTP-BINDING PROTEINS. ]
ran GTP-Binding Protein D020931 [A monomeric GTP-binding protein involved in nucleocytoplasmic transport of proteins into the nucleus and RNA into the cytoplasm. This enzyme was formerly listed as EC 3.6.1.47. ]
rap GTP-Binding Proteins D020668 [A family of MONOMERIC GTP-BINDING PROTEINS that are related to RAS PROTEINS.This enzyme was formerly listed as EC 3.6.1.47. ]
rap1 GTP-Binding Proteins D020827 [A genetically related subfamily of RAP GTP-BINDING PROTEINS that share homology with RAS PROTEINS. They bind to Ras effectors but do not activate them, therefore they may antagonize the effects of RAS PROTEINS. This enzyme was formerly listed as EC 3.6.1.47. ]
ras GTPase-Activating Proteins D020703 [PROTEINS that specifically activate the GTP-phosphohydrolase activity of RAS PROTEINS. ]
ras Guanine Nucleotide Exchange Factors D020663 [A family of GUANINE NUCLEOTIDE EXCHANGE FACTORS that are specific for RAS PROTEINS. ]
ras Proteins D018631 [Small, monomeric GTP-binding proteins encoded by ras genes (GENES, RAS). The protooncogene-derived protein, PROTO-ONCOGENE PROTEIN P21(RAS), plays a role in normal cellular growth, differentiation and development. The oncogene-derived protein ONCOGENE PROTEIN P21(RAS) can play a role in aberrant cellular regulation during neoplastic cell transformation (CELL TRANSFORMATION, NEOPLASTIC). This enzyme was formerly listed as EC 3.6.1.47. ]
