Tiagabine, a drug used as an anticonvulsant, acts by inhibiting the GABA transporter 1. Neurotransmitter transporters inhibitors Vesicular transporters could provide an alternative therapeutic target for the modulation of chemical neurotransmission, as the activity of these transporters could affect the quantity of neurotransmitter released.
Schematic diagram of the 2D structure of aquaporin 1 depicting the six transmembrane alpha-helices and the five interhelical loop regions A-E The 3D structure of aquaporin Z highlighting the 'hourglass'-shaped water channel that cuts through the center of the protein. Aquaporin proteins are composed of a bundle of six transmembrane α-helices ...
This bidirectional communication between astrocytes and neurons add complexity to brain signaling, with implications for brain function and neurological disorders. [10] [11] Enzyme degradation – proteins called enzymes break the neurotransmitters down. Reuptake – neurotransmitters are reabsorbed into the pre-synaptic neuron.
The structure of Sl6 family transporters share 20-25% sequence similarity with LeuTA [6] providing an evolutionary relationship between the transporter and the leucine transporter protein. [2] Because of the similarity, the LeuTa protein provides a very close template model for the studying the transporters in greater detail. [ 1 ]
The family of glutamate transporters is composed of two primary subclasses: the excitatory amino acid transporter (EAAT) family and vesicular glutamate transporter (VGLUT) family. In the brain, EAATs remove glutamate from the synaptic cleft and extrasynaptic sites via glutamate reuptake into glial cells and neurons , while VGLUTs move glutamate ...
The release is regulated by a voltage-dependent calcium channel. Vesicles are essential for propagating nerve impulses between neurons and are constantly recreated by the cell. The area in the axon that holds groups of vesicles is an axon terminal or "terminal bouton".

The relatively large chamber allows it to accommodate large head groups such as that present in lipid A. Significant conformational changes are required to move the large sugar head groups across the membrane. The difference between the two nucleotide-free (apo) structures is the ≈30° pivot of TM4/TM5 helices relative to the TM3/TM6 helices.
