Flotillin-1 is a protein that in humans is encoded by the FLOT1 gene.^[3]

Caveolae are small domains on the inner cell membrane involved in vesicular trafficking and signal transduction. FLOT1 encodes a caveolae-associated, integral membrane protein.^[4] The function of flotillin 1 has not been determined.^[3]

Interactions

FLOT1 has been shown to interact with SORBS1.^[5][6][7]
