What's a GeneRIF?

the role of phosducin at the rod-to-rod bipolar cell (RBC) synapse
Title: Absence of synaptic regulation by phosducin in retinal slices.
A major regulatory component responsible for setting the sensitivity of signal transmission between photoreceptors and ON-bipolar cells is confined to photoreceptors and that phosducin participates in the underlying molecular mechanism.
Title: Phosducin regulates transmission at the photoreceptor-to-ON-bipolar cell synapse.
Pdc-/- mice displayed exaggerated increases in blood pressure in response to post-operative stress.
Title: Phosducin influences sympathetic activity and prevents stress-induced hypertension in humans and mice.
Dopamine and other light-dependent processes cooperatively regulate the diurnal rhythm of phosducin phosphorylation. Dopamine release in response to light and circadian clocks drives daily rhythms of protein phosphorylation in photoreceptor cells.
Title: Dopamine modulates diurnal and circadian rhythms of protein phosphorylation in photoreceptor cells of mouse retina.
Phosducin does not contribute to adaptation mechanisms of the outer segment by dynamically controlling heterotrimer availability, but is necessary for maintaining normal transducin expression and therefore normal flash sensitivity in rods.
Title: Phosducin regulates the expression of transducin betagamma subunits in rod photoreceptors and does not contribute to phototransduction adaptation.
phosducin has a role in regulating signaling in the rod outer segment compartment and there are distinct functions for phosphorylation sites 54 and 71
Title: Compartment-specific phosphorylation of phosducin in rods underlies adaptation to various levels of illumination.
data suggest that phosducin action is based on the reduction of transducin affinity to the membranes of rod outer segments, achieved by keeping the transducin beta gamma subunits apart from the alpha subunit
Title: Phosducin facilitates light-driven transducin translocation in rod photoreceptors. Evidence from the phosducin knockout mouse.
The increased retinal degeneration 1 phosducin phosphorylation coincided with increased activation of calcium/calmodulin-activated protein kinase II, which is known to utilize phosducin as a substrate.
Title: Differential modification of phosducin protein in degenerating rd1 retina is associated with constitutively active Ca2+/calmodulin kinase II in rod outer segments.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
