VMAT Inhibitors
The vesicular monoamine transporter (VMAT) is a transport protein integrated into the membranes of synaptic vesicles of synapse, presynaptic neurons. It transports monoamine neurotransmitters – such as dopamine, serotonin, norepinephrine, epinephrine, and histamine – into the Vesicle (biology and chemistry), vesicles, which release the neurotransmitters into synapses as chemical messages to postsynaptic neurons. VMATs utilize a Electrochemical gradient, proton gradient generated by V-ATPases in vesicle membranes to power monoamine import. Pharmaceutical drugs that target VMATs have possible applications for many conditions, leading to a plethora of biological research, including hypertension, Drug-addiction, drug addiction, psychiatric disorders, Parkinson's disease, and other neurological disorders. Many drugs that target VMATs act as inhibitors and alter the kinetics of the protein. Much research regarding the effects of altered VMATs on biological systems is still ongoing. ...

Transport Protein
A transport protein (variously referred to as a transmembrane pump, transporter, escort protein, acid transport protein, cation transport protein, or anion transport protein) is a protein that serves the function of moving other materials within an organism. Transport proteins are vital to the growth and life of all living things. There are several different kinds of transport proteins. Carrier proteins are proteins involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. Carrier proteins are integral membrane proteins; that is, they exist within and span the membrane across which they transport substances. The proteins may assist in the movement of substances by facilitated diffusion (i.e., passive transport) or active transport. These mechanisms of movement are known as carrier-mediated transport. Each carrier protein is designed to recognize only one substance or one group of very similar substances. Researc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
