Protein: Probable G-protein coupled receptor 179 (Q6PRD1)
Organism: Homo sapiens (Human)
Function: Orphan receptor involved in vision. Required for signal transduction through retinal depolarizing bipolar cells. Acts as an atypical G- protein coupled receptor that recruits and regulates the R7 group RGS- GNB5 complexes instead of activating G proteins: promotes the GTPase activator activity of R7 RGS proteins, increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP-bound form (By similarity). Associates with components of metabotropic signaling cascade in retina ON-bipolar neurons, such as TRPM1 and GRM6: may control the ability of the GRM6 cascade to gate TRPM1 (By similarity)
Subcellular location: Cell membrane; Multi-pass membrane protein. Postsynaptic cell membrane ; Multi-pass membrane protein . Cell projection, dendrite. Note=Specifically localizes to the tips of retinal ON-bipolar dendrites
