Cancer: Altered actin dynamics can influence cell migration and invasion, contributing to cancer metastasis. Cardiovascular Diseases: Mutations in actin or actin-binding proteins can affect heart muscle function, leading to cardiomyopathies. Neurodegenerative Diseases: Abnormal actin dynamics are implicated in diseases like Alzheimer’s and Parkinson’s. Immune Disorders: Proper actin function is essential for immune cell motility and function; its dysregulation can lead to immune deficiencies.
