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