General annotation (Comments)
Acts as a regulator of G protein signaling (RGS). Modulates G protein alpha subunits nucleotide exchange and hydrolysis activities by functioning either as a GTPase-activating protein (GAP), thereby driving G protein alpha subunits into their inactive GDP-bound form, or as a GDP-dissociation inhibitor (GDI). Confers GDI activity on G(i) alpha subunits GNAI1 and GNAI3, but not G(o) alpha subunit GNAO1 and G(i) alpha subunit GNAI2. Confers GAP activity on G(o) alpha subunit GNAI0 and G(i) alpha subunits GNAI2 and GNAI3. May act as a scaffold integrating G protein and Ras/Raf MAPkinase signaling pathways. Inhibits platelet-derived growth factor (PDGF)-stimulated ERK1/ERK2 phosphorylation; a process depending on its interaction with HRAS1 and that is reversed by G(i) alpha subunit GNAI1. Acts as a positive modulator of microtubule polymerisation and spindle organization through a G(i)-alpha-dependent mechanism. Plays a role in cell division; required for completion of the first mitotic division of the embryo. Involved in visual memory processing capacity; when overexpressed in the V2 secondary visual cortex area. Involved in hippocampal-based learning and memory; acts as a suppressor of synaptic plasticity in CA2 neurons. Required for the nerve growth factor (NGF)-mediated neurite outgrowth. Involved in stress resistance. Ref.5 Ref.6 Ref.7 Ref.8 Ref.10 Ref.13
Found in a complex with at least BRAF, HRAS1, MAP2K1, MAPK3 and RGS14. Interacts with RIC8A (via C-terminus). Interacts (via RBD 1 domain) with HRAS1 (active GTP-bound form preferentially). Interacts (via RBD domains) with BRAF (via N-terminus); the interaction mediates the formation of a ternary complex with RAF1. Interacts (via RBD domains) with RAF1 (via N-terminus); the interaction mediates the formation of a ternary complex with BRAF. Interacts with KRAS (active GTP-bound form preferentially), MRAS (active GTP-bound form preferentially), NRAS (active GTP-bound form preferentially) and RRAS (active GTP-bound form preferentially). Interacts with GNAI1 (via active GTP- or inactive GDP-bound forms); the interaction prevents association of RGS14 with centrosomes or nuclear localization. Interacts with GNAI2. Interacts with GNAI3 (via active GTP- or inactive GDP-bound forms); the interaction prevents association of RGS14 with centrosomes or nuclear localization. Associates with microtubules By similarity. Interacts with GNAO1 and GNAI2. Interacts (via RGS and GoLoco domains) GNAI1; the interaction occurs in the centrosomes. Interacts with RABGEF1; the interactions is GTP-dependent. Interacts with RAP2A; the interactions is GTP-dependent and does not alter its function on G(i) alpha subunits either as GAP or as GDI. Ref.5 Ref.6 Ref.11
Nucleus. Nucleus › PML body. Cytoplasm. Membrane. Cell membrane By similarity. Cytoplasm › cytoskeleton › spindle. Cytoplasm › cytoskeleton › spindle pole By similarity. Cytoplasm › cytoskeleton › centrosome. Cell projection › dendrite. Cell projection › dendritic spine. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density. Note: Localizes with spindle poles during metaphase. Shuttles between the nucleus and cytoplasm in a CRM1-dependent manner. Recruited from the cytosol to the plasma membrane by the inactive GDP-bound forms of G(i) alpha subunits GNAI1 and GNAI3. Recruited from the cytosol to membranes by the active GTP-bound form of HRAS1. Colocalizes with G(i) alpha subunit GNAI1 and RIC8A at the plasma membrane. Colocalizes with BRAF and RAF1 in both the cytoplasm and membranes By similarity. Associates with the perinuclear sheaths of microtubules (MTs) surrounding the pronuclei, prior to segregating to the anastral mitotic apparatus and subsequently the barrel-shaped cytoplasmic bridge between the nascent nuclei of the emerging 2-cell embryo. Localizes to a perinuclear compartment near the microtubule-organizing center (MTOC). Expressed in the nucleus during interphase and segregates to the centrosomes and astral MTs during mitosis. Shuttles between the nucleus and cytoplasm in a CRM1-dependent manner. Relocalizes to the nucleus in PML nuclear bodies in respons to heat stress. Colocalizes with RIC8A in CA2 hippocampal neurons. Ref.5 Ref.8 Ref.9 Ref.13 Ref.14
Expressed in pyramidal neurons of the CA1, CA2 and fasciola cinerea (FC) subregions of the hippocampus and in the olfactory cortex (at protein level). Expressed in brain, spleen, heart, liver, lung, kidney, skin and thymus (at protein level). Expressed in granular layer of the cerebellum, forbrain, striatum, layer V of the cortex, olfactory cortex, tubercules, subthalamic and hippocampus, particularly in the CA2 region, to a lesser extent in the CA1 region and the external layer of the dentate gyrus. Expressed in neurons. Ref.5 Ref.7 Ref.13 Ref.14
Expressed in germinal vesicle oocytes, not in metaphase II oocytes. Expressed in embryo from 8.5 through 16.5 dpc (at protein level). Expressed in the zygote through to the blastocyst stage. Expressed in area lateral to the rhombencephalic floor plate at 12 dpc. Expressed in the anterior region of the brain, including the telencephalic olfactive nuclei and the hippocampus anlage at 17 dpc. Ref.5 Ref.7
The RGS domain is necessary for GTPase-activating protein (GAP) activity for G subunits and localization to the nucleus and centrosomes By similarity.
The GoLoco domain is necessary for GDP-dissociation inhibitor (GDI) activity, translocation out of the nucleus and interaction with G(i) alpha subunits GNAI1, GNAI2 and GNAI3 By similarity.
The RBD domains are necessary for localization to the nucleus and centrosomes By similarity.
Phosphorylated by PKC. Phosphorylation is increased in presence of forskolin and may enhance the GDI activity on G(i) alpha subunit GNAI1 By similarity.
No visible phenotype. Mice show an enhancement of postsynaptic long-term potentiation (LTP) responses in the CA2 neurons of the hippocampus that is correlated with an increase of spatial learning and object recognition memory (OMR). Ref.7 Ref.13
Contains 1 GoLoco domain.
Contains 2 RBD (Ras-binding) domains.
