Beta-actin is a 375 amino acid globular protein that binds ATP. It consists of four subdomains (SD1-SD4) that undergo conformational changes during the ATP hydrolysis cycle. The protein forms F-actin filaments through polymerization, with each monomer binding one ATP. Actin filaments are polarized with plus (barbed) and minus (pointed) ends. Beta-actin contains binding sites for over 100 actin-binding proteins that regulate its dynamics.
Beta-actin is a fundamental cytoskeletal protein essential for:
In neurons, beta-actin localizes to dendritic spines where it regulates spine morphology, size, and stability. Activity-dependent actin polymerization in spines is essential for long-term potentiation (LTP) and memory formation.
Dysregulation of beta-actin contributes to neurodegenerative diseases:
