The plasma membrane monoamine transporter ( PMAT) is a low-affinity monoamine transporter protein which in humans is encoded by the SLC29A4 gene. [1] It is known alternatively as the human equilibrative nucleoside transporter-4 (hENT4). It was discovered in 2004 [2] and has been identified as a potential alternate target for treating various ...
Monoamine transporters ( MATs) are proteins that function as integral plasma-membrane transporters to regulate concentrations of extracellular monoamine neurotransmitters. The three major classes are serotonin transporters (SERTs), dopamine transporters (DATs), and norepinephrine transporters (NETs) and are responsible for the reuptake of their ...
hide. PMAT may refer to: Plasma membrane monoamine transporter (PMAT) Four phases of mitosis: prophase, metaphase, anaphase, and telophase. Prophase: Chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres. Metaphase: Chromosomes line up along the metaphase plate (centre of the cell).
The vesicular monoamine transporter (VMAT) is a transport protein integrated into the membranes of synaptic vesicles of presynaptic neurons. It transports monoamine neurotransmitters – such as dopamine, serotonin, norepinephrine, epinephrine, and histamine – into the vesicles, which release the neurotransmitters into synapses, as chemical ...
A serotonin–norepinephrine–dopamine reuptake inhibitor ( SNDRI ), also known as a triple reuptake inhibitor ( TRI ), is a type of drug that acts as a combined reuptake inhibitor of the monoamine neurotransmitters serotonin, norepinephrine, and dopamine. It does this by concomitantly inhibiting the serotonin transporter (SERT ...
Uniform Appraisal Dataset is a component of the Uniform Mortgage Data Program, an initiative undertaken by Fannie Mae and Freddie Mac (together known as the GSEs) under the direction of the Federal Housing Finance Agency in the United States in order to comprehensively standardize mortgage loan data so that loans may be processed more ...
Uric acid is a heterocyclic compound of carbon, nitrogen, oxygen, and hydrogen with the formula C 5 H 4 N 4 O 3. It forms ions and salts known as urates and acid urates, such as ammonium acid urate. Uric acid is a product of the metabolic breakdown of purine nucleotides, and it is a normal component of urine. [ 1]
In cells stably expressing PMAT and SERT, the apparent affinity of recombinant PMAT for 5-HT is much lower than that of SERT (Km, 114 v.s. 0.5 μM) [12, 15]. However, PMAT also has a much larger transport capacity (Vmax), resulting in roughly comparable uptake efficiencies (Vmax/Km) to SERT in heterologous expression systems
