Protein Family: Adenylyl cyclase family, ATP-cited lyases [5]
ADCY1 (Adenylyl Cyclase 1), also known as adenylate cyclase 1 or brain-type adenylyl cyclase, is a calcium-stimulated enzyme that catalyzes the conversion of ATP to cyclic AMP (cAMP). ADCY1 is one of ten mammalian adenylyl cyclase isoforms and is uniquely activated by calcium/calmodulin, making it a key calcium-cAMP signaling nexus in neurons. It is primarily expressed in the brain, particularly in the hippocampus, cerebral cortex, and cerebellum, where it plays crucial roles in synaptic plasticity, learning, memory, and various neuronal signaling pathways.

ADCY1 is a integral membrane protein with characteristic adenylyl cyclase architecture: [7]
ADCY1 catalyzes:
ATP → cAMP + PPi
ADCY1 integrates multiple signals:
ADCY1 shows brain-specific expression:
The study of Adcy1 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.
