| Gene Symbol | RGS12 |
| Aliases | Regulator of G Protein Signaling 12 |
| Chromosome | 10q26.3 |
| Protein Type | Gene |
| Function | is a member of the RGS protein family that plays critical roles in modulating G protein-coupled receptor (GPCR) signaling in neurons. |
| Amino Acids | 447 aa |
| GeneCards | RGS12 |
| Human Protein Atlas | RGS12 |
| RGS12-Specific Regions | N-terminal and C-terminal regions contain proline-rich sequences that mediate interactions with SH3 domain-containing proteins including Grb2 and Crk. |
| Hippocampus | Highest expression in CA1-CA3 pyramidal neurons and dentate gyrus granule cells[@zheng2017]. The hippocampus-dependent learning paradigms strongly implicate RGS12 in memory formation. |
| Cerebral Cortex | Enriched in layer V pyramidal neurons, consistent with its role in cortico-cortical connectivity and higher cognitive functions. |
| Basal Ganglia | Moderate expression in striatal medium spiny neurons (MSNs) and substantia nigra pars compacta dopaminergic neurons[@snyder2014], regions pivotal for motor control and Parkinson's disease pathology. |
| Cerebellum | Expression in Purkinje cells suggests roles in motor learning and coordination. |
| Postsynaptic Dendrites | Concentrated in dendritic spines where it modulates postsynaptic signaling |
| Axon Initial Segions | Positioned to regulate action potential initiation |
| Associated Diseases | Alzheimer's disease, Parkinson's disease |
