| Gene Symbol | GNB5PROTEIN |
| Function | is a unique member of the heterotrimeric G protein β subunit family that plays crucial roles in synaptic signaling, retinal phototransduction, and cerebellar function. |
| Primary Expression | the brain, particularly in the cerebellum, hippocampus, and retina, where it regulates critical signaling pathways involved in motor control, learning |
| Subcellular Localization | </th><td>Cytoplasm, membrane-associated</td></tr> |
| Amino Acids | 377 aa |
| GeneCards | GNB5PROTEIN |
| Human Protein Atlas | GNB5PROTEIN |
| Seven WD40 repeat domains | Form a β-propeller structure that mediates protein-protein interactions with Gγ subunits and effectors |
| Switch regions (I, II, III) | Undergo conformational changes upon GDP/GTP exchange on the Gα subunit, controlling the interaction interface |
| Unique N-terminal extension | Contains binding sites for Regulator of G protein Signaling (RGS) proteins |
| WD40 repeats 1-7 | Each repeat forms a β-sheet of four antiparallel strands, creating the propeller structure |
| N-terminal extension | Unique to β5 subunits, contains RGS protein interaction motifs |
| C-terminal coiled-coil | Mediates Gγ subunit binding and dimer formation |
| Synaptic transmission | Regulates presynaptic Ca²⁺ channels and neurotransmitter release |
| Neuronal development | Controls neurite outgrowth and synapse formation during development |
