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.
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 ]
Facilitated diffusion may occur through three mechanisms: uniport, symport, or antiport. The difference between each mechanism depends on the direction of transport, in which uniport is the only transport not coupled to the transport of another solute. [4] Uniporter carrier proteins work by binding to one molecule or substrate at a time ...
Unlike channel proteins which only transport substances through membranes passively, carrier proteins can transport ions and molecules either passively through facilitated diffusion, or via secondary active transport. [12] A carrier protein is required to move particles from areas of low concentration to areas of high concentration.
The rate of ion transport through the channel is very high (often 10 6 ions per second or greater). Ions pass through channels down their electrochemical gradient , which is a function of ion concentration and membrane potential, "downhill", without the input (or help) of metabolic energy (e.g. ATP , co-transport mechanisms, or active transport ...
It was discovered that the minor allele of a single nucleotide polymorphism at GABBR1 known as rs1186902 is significantly associated with a later age of onset for migraines, [57] but for the other SNPs, no differences were discovered between genetic and allelic variations in the control vs. migraine participants.

The typical Hodgkin–Huxley model treats each component of an excitable cell as an electrical element (as shown in the figure). The lipid bilayer is represented as a capacitance (C m). Voltage-gated ion channels are represented by electrical conductances (g n, where n is the specific ion channel) that depend on both voltage and time.
