The vesicle coat serves to sculpt the curvature of a donor membrane, and to select specific proteins as cargo. It selects cargo proteins by binding to sorting signals.

Vesicle In cell biology, a vesicle is a relatively small and enclosed compartment, separated from the cytosol by at least one lipid bilayer. Vesicles store, transport, or digest cellular products and wastes.

seminal vesicles Glands that contribute fructose to sperm. The fructose serves as an energy source. The structures that add fructose and hormones to semen. PICTURE ... Full article ...

Germinal vesicle [L. germinis - bud, offshoot; L. vesicula- bladder]. The greatly enlarged nucleus of an oocyte.

The GTPase dynamin I is essential for synaptic vesicle endocytosis in nerve terminals.

membrane-bound organelle in the head of a sperm that is derived from the golgi apparatus; the vesicle containing enzymes that digest proteins and complex sugars in the outer coverings of an egg.

vesicles Small membrane-bound spaces in most plant and animal cells that transport macromolecules into and out of the cell and carry materials between organelles in the cell.

vesicles Membrane-bound particles pinched off by constriction of a membrane, as in the Golgi apparatus. vesicular disease Any disease of the urinary bladder, such as vesicular schistosomiasis.

Vesicles containing molecules from the endoplasmic reticulum arrive at the cis face of the golgi complex. Chemical reactions within the Golgi complex modify the molecules.

the vesicles make a brief contact at the plasma membrane, release their contents (neurotransmitters in this case) to the exterior, and then retreat back into the cytosol.

seminal vesicle [L. semen, seed + vesicula, a little bladder] A gland in males that secretes a fluid (a component of semen) that lubricates and nourishes sperm. seminiferous tubules ...

seminal vesicles Apart of the male reproductive tract that stores sperm in invertebrates and produces semen in vertebrates. seminiferous tubules Highly coiled tubes in the testes in which sperm are produced.

Synaptic Vesicles Synaptic vesicles fuse with the presynaptic membrane, freeing neurotransmitter molecules into the synaptic space. View QuickTime Movie ...

microplasts Vesicles produced by subdivision and fragmentation of protoplasts or thin-walled cells. micropyle 1. A small opening in the surface of a plant ovule through which the pollen tube passes prior to fertilization.

An organism whose cells possess a nucleus and other membrane-bound vesicles, including all members of the protist, fungi, plant and animal kingdoms; and excluding viruses, bacteria, and blue-green algae. See Prokaryote. Evolution.

endocytosis The uptake of extracellular material by its inclusion within a vesicle (endosome) formed by an invagination of the plasma membrane.

We report on the use of coupled high resolution separation and high mass accuracy and sensitivity Fourier transform ion cyclotron resonance (FTICR) mass spectrometry to characterize the protein content of outer membrane vesicles from the ...

Both insulin and digestive enzymes are made in the RER and modified and packaged into vesicles in the Golgi apparatus. These vesicles are released by the cell by a process known as exocytosis.

Liposomes. Membrane-bound vesicles constructed in the laboratory to transport biological molecules. Locus (plural = loci). A specific location or site on a chromosome. Log phase. See Logarithmic phase.

liposomes - synthetic bilayer in the form of a spherical vesicle membrane potential - voltage difference across a membrane due to a slight excess of positive ions on one side and of negative ions on the other ...

An infection of the epidermis, spread by contact, that produces vesicles or pustules, which rupture and become covered with crusts.
