Located in the contractile vacuolar membrane such that some covalently attached portion of the gene product, for example part of a peptide sequence or some other covalently attached moiety such as a GPI anchor, spans or is embedded in one or both leaflets of the membrane. A closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. Cells contain one or several vacuoles, that may have different functions from each other. Vacuoles have a diverse array of functions. They can act as a storage organelle for nutrients or waste products, as a degradative compartment, as a cost-effective way of increasing cell size, and as a homeostatic regulator controlling both turgor pressure and pH of the cytosol. The lipid bilayer surrounding the vacuole and separating its contents from the cytoplasm of the cell. The lipid bilayer surrounding the contractile vacuole. Stable structure that regulates the flow of liquid between the contractile vacuole and the surrounding medium. Any small, fluid-filled, spherical organelle enclosed by a lipid bilayer. The lipid bilayer surrounding an organelle. Any constituent part of a vacuole, a closed structure, found only in eukaryotic cells, that is completely surrounded by unit membrane and contains liquid material. A specialized vacuole of eukaryotic cells, especially Protozoa, that fills with water from the cytoplasm and then discharges this externally by the opening of contractile vacuole pores. Its function is probably osmoregulatory.
