ID:GBLP_MOUSE DESCRIPTION: RecName: Full=Guanine nucleotide-binding protein subunit beta-2-like 1; AltName: Full=12-3; AltName: Full=Receptor for activated C kinase; AltName: Full=Receptor of activated protein kinase C 1; Short=RACK1; AltName: Full=p205; FUNCTION: Involved in the recruitment, assembly and/or regulation of a variety of signaling molecules. Interacts with a wide variety of proteins and plays a role in many cellular processes. Component of the 40S ribosomal subunit involved in translational repression. Binds to and stabilizes activated protein kinase C (PKC), increasing PKC-mediated phosphorylation. May recruit activated PKC to the ribosome, leading to phosphorylation of EIF6. Inhibits the activity of SRC kinases including SRC, LCK and YES1. Inhibits cell growth by prolonging the G0/G1 phase of the cell cycle. Enhances phosphorylation of BMAL1 by PRKCA and inhibits transcriptional activity of the BMAL1-CLOCK heterodimer. Facilitates ligand- independent nuclear translocation of AR following PKC activation, represses AR transactivation activity and is required for phosphorylation of AR by SRC. Modulates IGF1R-dependent integrin signaling and promotes cell spreading and contact with the extracellular matrix. Involved in PKC-dependent translocation of ADAM12 to the cell membrane. Promotes the ubiquitination and proteasome-mediated degradation of proteins such as CLEC1B and HIF1A. Required for VANGL2 membrane localization, inhibits Wnt signaling, and regulates cellular polarization and oriented cell division during gastrulation. Required for PTK2/FAK1 phosphorylation and dephosphorylation. Regulates internalization of the muscarinic receptor CHRM2. Promotes apoptosis by increasing oligomerization of BAX and disrupting the interaction of BAX with the anti-apoptotic factor BCL2L. Inhibits TRPM6 channel activity. Regulates cell surface expression of some GPCRs such as TBXA2R. Plays a role in regulation of FLT1-mediated cell migration. SUBUNIT: Component of the small (40S) ribosomal subunit. Exists as a monomer and also forms oligomers. Binds SLC9A3R1. Forms a ternary complex with TRIM63 and PRKCE. Interacts with HABP4, KRT1 and OTUB1. Interacts with SRC (via SH2 domain); the interaction is enhanced by tyrosine phosphorylation of GNB2L1/RACK1. Recruited in a circadian manner into a nuclear complex which also includes BMAL1 and PRKCA. Interacts with AR. Interacts with IGF1R but not with INSR. Interacts with ADAM12. Interacts with CLEC1B (via N- terminal region) and with HIF1A; the interaction promotes their degradation. Interacts with RHOA; this enhances RHOA activation and promotes cell migration. Interacts with CHRM2; the interaction regulates CHRM2 internalization. Interacts with TRPM6 (via kinase domain). Interacts with PTK2/FAK1; required for PTK2/FAK1 phosphorylation and dephosphorylation. Interacts with FLT1. Interacts with HRAS. INTERACTION: O88351:Ikbkb; NbExp=4; IntAct=EBI-296749, EBI-447960; SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein (By similarity). Cytoplasm (By similarity). Cytoplasm, perinuclear region (By similarity). Cytoplasm, cytoskeleton (By similarity). Nucleus. Perikaryon. Cell projection, dendrite. Note=Recruited to the plasma membrane through interaction with KRT1 which binds to membrane-bound ITGB1. PKC activation induces translocation from the perinuclear region to the cell periphery. In the brain, detected mainly in cell bodies and dendrites with little expression in axonal fibers or nuclei (By similarity). TISSUE SPECIFICITY: Strongly and ubiquitously expressed in the embryonic and early postnatal brain. At E11.5, expressed in a high-dorsal to low-ventral gradient throughout the brain. At E13.5, most abundant in the telecephalon. At E18.5, expressed most abundantly in layers 1-4 of the cortex, striatum, hippocampus, dentate gyrus, and specific thalamic nuclei. This expression decreases during postnatal development and is localized in the dentate gyrus, habenula, piriform cortex, paraventricular nucleus of the hypothalamus and supraoptic nucleus of the adult brain. DEVELOPMENTAL STAGE: Expressed throughout embryonic brain development with high levels detected at E11.5, E13.5 and E18.5. Also detected at high levels in the adult brain. PTM: Phosphorylated on Tyr-228 and/or Tyr-246 by SRC. This is required for binding to SRC (By similarity). SIMILARITY: Belongs to the WD repeat G protein beta family. SIMILARITY: Contains 7 WD repeats. SEQUENCE CAUTION: Sequence=AAG29506.1; Type=Frameshift; Positions=232, 239;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
