Adcy5 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The ADCY5 gene encodes adenylate cyclase 5 (AC5), a G protein-regulated adenylyl cyclase highly expressed in striatal neurons. AC5 is a major effector of dopamine D1 receptor signaling and plays critical roles in motor control and reward processing.
Adenylate cyclase 5 is a membrane-bound enzyme:
- G Protein Regulation: Activated by Gs alpha subunits, inhibited by Gi alpha subunits
- Dopamine Signaling: Primary adenylyl cyclase mediating D1 receptor effects in striatum
- cAMP Production: Generates cAMP in response to dopamine, adenosine, and other neuromodulators
- Motor Control: Critical for basal ganglia circuit function
- Expression: Highest in striatum (caudate, putamen), nucleus accumbens, cortex
- ADCY5 mutations cause autosomal dominant dyskinesia
- Characterized by choreiform movements, facial myokymia
- Often presents in infancy or childhood
- ADCY5 polymorphisms modify PD risk
- Altered AC5 function in PD substantia nigra
- Contributes to dopaminergic signaling deficits
- Therapeutic target consideration
- Altered cAMP signaling in HD striatum
- AC5 dysfunction contributes to medium spiny neuron degeneration
- Brain Regions: Highest in striatum (caudate nucleus, putamen), nucleus accumbens, cerebral cortex, hippocampus
- Subcellular Localization: Plasma membrane of dendritic shafts and spines
- Regulation: Gs alpha (activation), Gi alpha (inhibition), PKA (feedback inhibition)
