Adenylate Cyclase 1 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 1 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 1 (AC1), also known as ADCY1, is a calcium/calmodulin-activated adenylyl cyclase that catalyzes the conversion of ATP to cyclic AMP (cAMP). It is primarily expressed in neuronal tissue and plays critical roles in synaptic plasticity, learning, and memory.
AC1 is a ~1250 amino acid membrane protein with:
- 12 Transmembrane Helices: Organized in 6 TMD pairs
- Cytosolic C1a and C2a Domains: Form the catalytic core
- Calmodulin-Binding Domain: Located in the N-terminus
- Alternative Names: AC1, ADCY1
- Catalyzes ATP → cAMP + PPi reaction
- Activated by calcium-calmodulin complex
- Unique among AC isoforms for direct CaM activation
- Activates protein kinase A (PKA)
- Generates cAMP for EPAC activation
- Modulates cyclic nucleotide-gated (CNG) channels
- Synaptic plasticity in hippocampus
- Memory consolidation
- Olfactory and auditory signal transduction
- Altered cAMP/PKA/CREB signaling in AD
- Amyloid-beta impairs AC1 function
- Memory consolidation deficits
- Striatal cAMP signaling dysregulation
- Dopaminergic modulation of AC1

ADCY1 expression in the nervous system:
- Highest expression in hippocampus
- Present in cerebral cortex
- Detected in cerebellum
- Expressed in olfactory bulb
ADCY1 is regulated by:
- Gs protein stimulation
- Calcium/calmodulin (brain-specific regulation)
- Protein kinase C phosphorylation
- Forskolin activation
- Memory and learning mechanisms
- cAMP signaling in neurodegeneration
- Therapeutic targeting in AD/PD
- Understanding isoform-specific functions
The study of Adenylate Cyclase 1 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
