Description: Homo sapiens regulator of G protein signaling 9 binding protein (RGS9BP), mRNA. RefSeq Summary (NM_207391): The protein encoded by this gene functions as a regulator of G protein-coupled receptor signaling in phototransduction. Studies in bovine and mouse show that this gene is expressed only in the retina, and is localized in the rod outer segment membranes. This protein is associated with a heterotetrameric complex, specifically interacting with the regulator of G-protein signaling 9, and appears to function as the membrane anchor for the other largely soluble interacting partners. Mutations in this gene are associated with prolonged electroretinal response suppression (PERRS), also known as bradyopsia. [provided by RefSeq, Mar 2010]. Transcript (Including UTRs) Position: hg19 chr19:33,166,313-33,169,206 Size: 2,894 Total Exon Count: 1 Strand: + Coding Region Position: hg19 chr19:33,167,170-33,167,877 Size: 708 Coding Exon Count: 1
ID:R9BP_HUMAN DESCRIPTION: RecName: Full=Regulator of G-protein signaling 9-binding protein; AltName: Full=RGS9-anchoring protein; FUNCTION: Regulator of G protein-coupled receptor (GPCR) signaling in phototransduction. Participates in the recovery phase of visual transduction via its interaction with RGS9-1 isoform. Acts as a membrane-anchor that mediates the targeting of RGS9-1 to the photoreceptor outer segment, where phototransduction takes place. Enhances the ability of RGS9-1 to stimulate G protein GTPase activity, allowing the visual signal to be terminated on the physiologically time scale. It also controls the proteolytic stability of RGS9-1, probably by protecting it from degradation (By similarity). SUBUNIT: Specifically interacts with isoform RGS9-1 of RGS9. Component of the RGS9-1-Gbeta5 complex composed of RGS9-1, Gbeta5 (GNB5) and RGS9BP (By similarity). SUBCELLULAR LOCATION: Membrane; Single-pass type IV membrane protein (By similarity). DISEASE: Defects in RGS9BP are a cause of prolonged electroretinal response suppression (PERRS) [MIM:608415]; also known as bradyopsia. PERRS is characterized by difficulty adjusting to sudden changes in luminance levels mediated by cones. SIMILARITY: Belongs to the RGS7BP/RGS9BP family.
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.
