What are two important second messengers used in the G protein-linked receptor mechanism?
i think its calcium ions
Describe gating mechanism existing in channels?
G protein-gated ion channels are specific ion channels located in the plasma membrane.
Is protein in sweetcorn?
3.2 g of protein in 100 g of sweetcorn.
What activates a G protein?
GTP activates a G-protein when it displaces the GDP.
Why G protein linked receptor is called as G protein linked receptor?
sciece
What is Transducin?
A G protein
Why did Edwin G. Krebs win The Nobel Prize in Physiology or Medicine in 1992?
The Nobel Prize in Physiology or Medicine 1992 was awarded jointly to Edmond H. Fischer and Edwin G. Krebs for their discoveries concerning reversible protein phosphorylation as a biological regulatory mechanism
When was G protein-coupled receptors database created?
G protein-coupled receptors database was created in 1998.
What is bound to the G protein in the inactive state?
GDP. Guanine diphosphate. Then the protein is phosphorylated and undergoes a conformational change in concert with its docking with the G protein linked receptor.
What is a regulatory protein associated with membrane-bound receptor molecules?
G protein
What has the author G M Fleck written?
G. M. Fleck has written: 'Chemical reaction mechanism'
Why g protein are coupled receptors?
The receptor it self is a trans-membrane protein and doesn't act as an ion channel further more the G-protein involves several functions by its different subunits (G-alph: activation of PLC and adenylcyclase. and G-beta,gamma: activation of potassium channel) and the receptor is coupled with more than one G-protein which lead to amplification of the signal. So G-protein could be possibly evolved to do several functions and amplify them by one receptor
