CAVIN1 (Caveolae Associated Protein 1): CAVIN1 is a crucial protein essential for the formation and function of caveolae — small invaginations of the plasma membrane involved in processes such as endocytosis and signal transduction. It aids lipid metabolism, endothelial health, and cellular mechanoprotection. Mutations in CAVIN1 are linked to conditions like lipodystrophy and muscular dystrophies, highlighting its role in cell structure and metabolism.
