Domain Architecture (Details)
InterPro domains assigned to SynO:
Neurotransmitter transport systems are integral to the release.e-uptake and recycling of neurotransmitters at synapses. High affinity transport proteins found in the plasma membrane of presynaptic nerve terminals and glial cells are responsible for the removal from the extracellular space of released-transmitters.hereby terminating their actions . Plasma membrane neurotransmitter transporters fall into two structurally and mechanistically distinct families. The majority of the transporters constitute an extensive family of homologous proteins that derive energy from the co-transport of Na+ and Cl-.n order to transport neurotransmitter molecules into the cell against their concentration gradient. The family has a common structure of 12 presumed transmembrane helices and includes carriers for gamma-aminobutyric acid (GABA).oradrenaline/adrenaline.opamine.erotonin.roline.lycine.holine.etaine and taurine. They are structurally distinct from the second more-restricted family of plasma membrane transporters.hich are responsible for excitatory amino acid transport. The latter couple glutamate and aspartate uptake to the cotransport of Na+ and the counter-transport of K+.ith no apparent dependence on Cl- .

Solutesutilised in this manner are referred to as osmolytes and include:glycerophosphorylcholine.etaine.yo-inositol.orbitol and taurine .Cell membrane transporters for betaine and taurine have been cloned.nd bysequence similarity they have been shown to belong to the Na+ and Cl--coupled neurotransmitter transporter superfamily. Functional studies ofthe cloned betaine transporter (BGT-1) have revealed that it can alsotransport GABA.nd that its mode of transport is electrogenic.ith uptakeof betaine depolarising the cell . In humans.he gene maps to chromosome12p13.nd is found to be expressed in: the kidney.rain.iver.eart.keletal muscle and placenta.

sdb:0004 Presynaptic compartment  (Evidence:keywords,domains)
supporting cells of the nervous system. Glial cells in the brain and spinal cord far outnumber nerve cells. They not only provide physical support, but also respond to injury, regulate the chemical composition surrounding cells, participate in the blood-brain and blood-spinal-cord barriers, form the myelin insulation of nervous pathways, help guide neuronal migration during development, and exchange metabolites with neurons. They may also produce substances that help and hinder regeneration in the spinal cord. The major types of glial cells in the CNS are astrocytes, oligodendrocytes, and microglia.
