Adenylate cyclase type 8 (ADCY8)

Target
ADCY8
Molecular classification
Enzyme, Adenylate cyclase family, Membrane-associated protein
01

Overview

Adenylate cyclase type 8 (ADCY8) is a membrane-bound enzyme that catalyzes the conversion of ATP to cyclic AMP (cAMP) in response to increases in intracellular calcium, integrating Ca²⁺ and cAMP signaling. ADCY8 is highly expressed in neurons, specifically at synaptic sites, and plays a key role in synaptic plasticity, learning, memory, and modulation of neuronal signaling. In the pancreas, ADCY8 is a critical component for glucose-stimulated cAMP production and insulin secretion. ADCY8 is regulated by G protein-coupled receptors and Ca²⁺/calmodulin, and its dysfunction has been linked to neurological and metabolic diseases, including anxiety, dissociative amnesia, and impaired insulin secretion in diabetes.

02

Mechanism of action

Drugs targeting the cAMP pathway may indirectly modulate ADCY8 activity by affecting upstream (G protein-coupled receptors) or downstream (protein kinase A, CREB) signaling

03

Biological functions

Signal transduction (conversion of ATP to cAMP)Synaptic plasticity (neuronal signaling)Calcium signaling (coupling Ca²⁺ influx to cAMP synthesis)Regulation of insulin secretion in pancreatic β-cells
04

Disease associations

Neurodegenerative disease (involved in learning, memory, anxiety modulation, addiction)Metabolic disorders (impaired incretin signaling, reduced insulin secretion)Other: Dissociative amnesia, anxiety
05

Safety considerations

Off-target effects on central nervous system and metabolic functions due to ADCY8’s broad role in neuronal signaling and insulin secretion
06

Interacting drugs

No directly approved drugs known to target ADCY8 specifically; however, downstream pathways (e.g., cAMP modulators, incretin mimetics) are targeted in therapeutics
07

Biomarkers

cAMP levels (as indirect measure of ADCY8 activity)Expression of synaptic proteins for neurological disorders
