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

Caveolae are small domains on the inner cell membrane involved in vesicular trafficking and signal transduction. FLOT1 encodes a caveolae-associated, integral membrane protein.^[2] The function of flotillin 1 has not been determined.^[1]

Interactions

FLOT1 has been shown to interact with SORBS1.^[3][4][5]
