snare

1. A contrivance, often consisting of a noose of cord, or the like, by which a bird or other animal may be entangled and caught; a trap; a gin.

3. The gut or string stretched across the lower head of a drum.

4. (Science: medicine) An instrument, consisting usually of a wireloop or noose, for removing tumours, etc, by avulsion. Snare drum, the smaller common military drum, as distinguished from the bass drum; so called because (in order to render it more resonant) it has stretched across its lower head a catgut string or strings.

Origin: AS. Sneara cord, a string; akin to D. Snoer, G. Schnur, OHG. Snour a cord, snarahha a noose, Dan. Snare, Sw. & Icel. Snara, Goth. Snrj a basket; and probably also to E. Needle. See Needle, and cf. Snarl to entangle.

Calcium ions

... synaptic cleft. When the neuron is not firing, some vesicles are tethered to the plasma membrane(mainly through Rab proteins, but not only; some SNARE interactions are also involved, but they are not at their full capacity). There is a protein(synaptotagmin) that binds the SNAREs and does not ...

protein modification and trafficking

... is done by means of trans & cis golgi complex by means of vesicles which carry the proteins to the targeted sites by the help of v & t SNARE proteins , Rab/GTP proteins and NFS/snaps complex . If this isn't protein trafficking can any suggest the correct way of protein modification ...

vacuole

... proteins are used really depends on where that particular vesicle is going. The two most common protein families used for this purpose are the SNARE proteins and the Rab proteins. But like I said, it depends. Hope this sheds some light on the subject

Re: On Calcium mediated exocytosis and the synaptotogmin fam

... mediated calcium channels, which cause an influx of calcium at that point. The calcium inactivates the protein synaptotogmin, which allows the SNARE complex to form and fusion of the vesicle with the membrane to take place. BUT some other processes seem to have a calicum-mediated exocytosis ...
