The protein encoded by this gene is located in the cytoplasm and is part of the GAP1 family of GTPase-activating proteins.

RAN Gene

RAN, member RAS oncogene family

RAN (ras-related nuclear protein) is a small GTP binding protein belonging to the RAS superfamily that is essential for the translocation of RNA and proteins through the nuclear pore complex. The RAN protein is also involved in control of DNA synthesis and cell cycle progression. Nuclear localization of RAN requires the presence of regulator of chromosome condensation 1 (RCC1). Mutations in RAN disrupt DNA synthesis. Because of its many functions, it is likely that RAN interacts with several other proteins. RAN regulates formation and organization of the microtubule network independently of its role in the nucleus-cytosol exchange of macromolecules. RAN could be a key signaling molecule regulating microtubule polymerization during mitosis. RCC1 generates a high local concentration of RAN-GTP around chromatin which, in turn, induces the local nucleation of microtubules. RAN is an androgen receptor (AR) coactivator that binds differentially with different lengths of polyglutamine within the androgen receptor. Polyglutamine repeat expansion in the AR is linked to Kennedy's disease (X-linked spinal and bulbar muscular atrophy). RAN coactivation of the AR diminishes with polyglutamine expansion within the AR, and this weak coactivation may lead to partial androgen insensitivity during the development of Kennedy's disease.

Located in early endosome; phagocytic vesicle; and trans-Golgi network membrane. Biomarker of severe acute respiratory syndrome. [provided by Alliance of Genome Resources, Mar 2025]

RAB30 Gene

RAB30, member RAS oncogene family

Predicted to enable GTP binding activity and GTPase activity. Involved in Golgi organization. Located in Golgi cisterna; cis-Golgi network; and trans-Golgi network. [provided by Alliance of Genome Resources, Mar 2025]

RAB38 Gene

RAB38, member RAS oncogene family

Enables several functions, including AP-1 adaptor complex binding activity; AP-3 adaptor complex binding activity; and BLOC-2 complex binding activity. Involved in several processes, including endosome to melanosome transport; melanosome assembly; and phagosome acidification. Located in several cellular components, including cytoplasmic vesicle; lysosome; and mitochondria-associated endoplasmic reticulum membrane contact site.

RAB3D Gene

RAB3D, member RAS oncogene family

Enables myosin V binding activity. Involved in bone resorption and positive regulation of regulated secretory pathway. Located in cytoplasmic microtubule and secretory vesicle. [provided by Alliance of Genome Resources, Mar 2025]

RAB3C Gene

RAB3C, member RAS oncogene family

This gene is a member of the RAS oncogene family and encodes a small GTPase. Other similar small GTPases are known to be involved in vesicle trafficking, and the encoded protein was shown to play a role in recycling phagocytosed MHC class 1 complexes to the cell surface. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

RAB3B Gene

RAB3B, member RAS oncogene family

Enables GDP binding activity; GTPase activity; and myosin V binding activity. Involved in several processes, including positive regulation of dopamine uptake involved in synaptic transmission; regulation of synaptic vesicle cycle; and regulation of vesicle size. Located in perinuclear region of cytoplasm and vesicle. Is active in dopaminergic synapse and synaptic vesicle membrane. [provided by Alliance of Genome Resources, Mar 2025]

RAB9AP3 Gene

RAB9A, member RAS oncogene family pseudogene 3

RSU1 Gene

Ras suppressor protein 1

This gene encodes a protein that is involved in the Ras signal transduction pathway, growth inhibition, and nerve-growth factor induced differentiation processes, as determined in mouse and human cell line studies. In mouse, the encoded protein was initially isolated based on its ability to inhibit v-Ras transformation. Multiple alternatively spliced transcript variants for this gene have been reported; one of these variants was found only in glioma tumors. [provided by RefSeq, Jul 2008]

RAS guanyl releasing protein 2 (calcium and DAG-regulated) pseudogene

RAB6D Gene

RAB6D, member RAS oncogene family

Predicted to enable GTPase activity. Predicted to be involved in several processes, including Golgi vesicle transport; protein localization to Golgi membrane; and retrograde transport, endosome to Golgi. Located in Golgi apparatus. [provided by Alliance of Genome Resources, Mar 2025]
