Adenylate Cyclase 5 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Adenylate Cyclase 5 Protein is an important protein/gene involved in various neurological processes. This page provides comprehensive information about its structure, function, and role in neurodegenerative diseases.
Adenylate Cyclase 5 (AC5), also known as ADCY5, is a G protein-regulated adenylyl cyclase isoform highly expressed in the striatum. It is a major effector of dopamine D1 receptor signaling and plays critical roles in motor control and reward processing.
AC5 is a ~1220 amino acid membrane protein:
- 12 Transmembrane Helices: Six TMD pairs
- Cytosolic C1a and C2a Catalytic Domains: Form the catalytic core
- Nucleotide Binding Sites: For ATP
- Alternative Names: AC5, ADCY5
- Activated by Gs alpha subunits
- Inhibited by Gi alpha subunits
- Primary effector of D1 receptor signaling
- Major AC isoform in striatum
- Mediates D1 receptor effects on motor control
- Generates cAMP in response to dopamine
- Critical for basal ganglia circuit function
- Modulates indirect and direct pathway activity
- Dyskinesia when overactive
- ADCY5 gain-of-function mutations cause disease
- Choreiform movements, facial myokymia
- Childhood onset
- Altered AC5 in substantia nigra
- Contributes to motor dysfunction
- Therapeutic target consideration
- Altered striatal cAMP signaling
- Medium spiny neuron dysfunction

- Dopamine D1 receptor activation
- Forskolin stimulation
- PKA phosphorylation
ADCY5 mutations cause:
- ADCY5-related dyskinesia
- Familial dyskinesia with facial myokymia
- Neurodevelopmental disorders
- Dopamine signaling in basal ganglia
- Motor control mechanisms
- Therapeutic targeting in PD
- Understanding cAMP dynamics in neurons
