Capzb 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.
CAPZB (Capping Actin Protein of the Z-disc Beta) is the beta subunit of the F-actin capping protein, a heterodimeric protein that regulates actin filament dynamics by binding to the barbed ends of actin filaments. This protein is essential for normal cytoskeletal function in all eukaryotic cells, with particular importance in muscle and neuronal cells. [1]

The capping protein consists of two subunits:
The heterodimer forms a barrel-like structure that caps actin filament barbed ends, preventing both polymerization and depolymerization at this end.
Current approaches targeting actin cytoskeleton regulators include:
The study of Capzb 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.
