CC   -!- FUNCTION: May confer stability to the gas vesicle membranes. Gas
CC       vesicles are small, hollow, gas filled protein structures that are
CC       found in several microbial planktonic microorganisms. They allow the
CC       positioning of the organism at the favorable depth for growth.
CC   -!- SUBCELLULAR LOCATION: Vacuole, gas vesicle membrane; Peripheral
CC       membrane protein; Cytoplasmic side. Note=Binds to the external surface
CC       of the gas vesicle membrane.
CC   -!- SIMILARITY: Belongs to the gas vesicle protein type C family.
CC       {ECO:0000305}.
