Mouse Caveolin-3, CAV3 ELI

May act as a scaffolding protein within caveolar membranes.

Interacts directly with G-protein alpha subunits and can functionally regulate their activity.

May also regulate voltage-gated potassium Channels.

Plays a role in the sarcolemma repair mechanism of both skeletal muscle and cardiomyocytes that permits rapid resealing of membranes disrupted by mechanical stress (PubMed: 19380584).

Mediates the recruitment of CAVIN2 and CAVIN3 proteins to the caveolae (By similarity).
