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.
Overview
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. [@additional]
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. [@research]
Structure
AC1 is a ~1250 amino acid membrane protein with: [@adenylate]
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
