CC   -!- FUNCTION: Found in functional membrane microdomains (FMM) that may be
CC       equivalent to eukaryotic membrane rafts. FMMs are highly dynamic and
CC       increase in number as cells age. Flotillins are thought to be important
CC       factors in membrane fluidity. {ECO:0000250|UniProtKB:O32076}.
CC   -!- SUBUNIT: Homooligomerizes. {ECO:0000250|UniProtKB:O32076}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Single-pass
CC       membrane protein {ECO:0000255}. Membrane raft
CC       {ECO:0000250|UniProtKB:O32076}; Single-pass membrane protein
CC       {ECO:0000255}.
CC   -!- SIMILARITY: Belongs to the band 7/mec-2 family. Flotillin subfamily.
CC       {ECO:0000305}.
