Gamma-actin shares 99% sequence similarity with beta-actin and has nearly identical three-dimensional structure. Both isoforms can copolymerize into mixed filaments. The subtle differences in amino acid sequence confer isoform-specific binding affinities for actin-binding proteins. Gamma-actin has specific post-translational modifications including acetylation and oxidation that regulate its function.
Gamma-actin is essential for:
In neurons, gamma-actin is enriched in dendritic spines and regulates spine morphology. It interacts with PSD-95 and other postsynaptic density proteins to maintain synaptic structure.
Gamma-actin mutations cause:
