In the specialized field of biochemical research, specific ligands are essential for understanding ion channel physiology. One such molecule that has garnered significant interest among researchers is the Ammtx3 peptide. As someone who follows the latest developments in peptide synthesis and ion channel modulation, I have spent considerable time reviewing the literature regarding this Dec 11, 2002—In addition,AmmTX3, a third relatedpeptide, competing with125I-labelled sBmTX3 for binding, was identified in the venom of Androctonus Read more fascinating compound.
Understanding the Ammtx3 Peptide
Ammtx3 is a peptide toxin originally isolated from the venom of the *Androctonus mauretanicus*, commonly known as the Moroccan black thick-tailed scorpion. From a structural perspective, it is a member of the α-KTX 15 family of toxins. It consists of a single chain of AmmTX3 TFA | Kv4 Channel Inhibitor 37 amino acid residues, characterized by an N-terminal pyroglutamate and stabilized by three disulfide bridges.
For those inquiring about its nature, it is important to note that AmmTX3 is a peptide toxin that has been the subject of extensive study due to its biological activity. It is a highly pure, synthetic, and biologically active peptide toxin often utilized in laboratory settings to investigate the complexities of cellular signaling.
Mechanism of Action and Ion Channel Selectivity
The primary utility of this compound in research lies in its function as a selective inhibitor. Specifically, AmmTX3 is a KV4 channel blocker. It has been shown to modulate the subthreshold-operating A-type K+ current, particularly in mouse cerebellar Search results of 90-64-2 granule neurons.
Research indicates that AmmTx3 appears to be a pore blocker of Kv4.2 and Kv4.3 channels. Interestingly, its efficacy appears to be enhanced by the presence of accessory dipeptidyl peptidase-like proteins (DPP), such as DPP6. This nuance in its binding affinity makes it a precise tool for researchers looking to map specific ion channel expressions. While some peptides interact with a broad spectrum of targets, the high specificity of this molecule is what distinguishes it in comparative studies.
Technical Specifications and Availability
When sourcing this material for *in vitro* analysis, purity is a paramount concern. High-qualit AmmTx3 Blocker of A-type potassium channels y preparations typically offer a purity of >98% as determined by HPLC, with a molecular weight of approximately 3822 Da.
It is worth noting that the commercial landscape for these reagents can be volatile. For instance, AmmTX3 MAGE-A3 (112-120) peptide - KVAELVHFL has been withdrawn from sale for commercial reasons by some major suppliers, which has led researchers to seek alternative synthesis routes, such as native chemical ligation. When evaluating different grades, you may encounter products labeled as AmmTX3 TFA, which is simply the trifluoroacetate salt form of the molecule. AmmTX3 TFA is a peptide toxin that retains the same functional characteristics as the native form.
Comparative Research and Considerations
In my review of the literature, I have encountered various discussions regarding its selectivity. For example, while some compounds are known as a peptide that blocks the hERG current, the specific profile of this scorpion-derived agent is distinct. AmmTx3 is distinct from other toxins like AaTX1, which shares a high sequence identity but differs in specific amino acid residues.
Whether you are looking at AmmTX3 for its role in spatial memory studies or its ability to block A-type potassium currents, it remains a cornerstone of ion channel pharmacology. Its classification as a member of the α-KTX 15 family ensures t AmmTx3 Toxin | Purity > 98% | #STA-305 hat it will continue to be a reference point for future studies involving scorpion-derived peptide synthesis and characterization.
