In the specialized field of peptide research, the structural composition of a compound is paramount to its functional utility. As Apolipoprotein E mimetic peptide, CN-105, improves someone who has spent years documenting the characteristics of various research-grade compounds, I have found that understanding the CN-105 peptide amino acid sequence is essential for any serious study regarding apolipoprotein E (apoE) mimetics.
Decoding the CN-105 Structure
The CN-105 compound is a fascinating subject for those interested in the architecture of short-chain molecules. At its core, it is a pentapeptide, which means it consists of five specific residues. The amino acid sequence is scientifically documented as A by H Wang · 2021 · Cited by 20 — We developed a 5-amino acid peptide, CN-105, that mimics the polar face of the apoE helical domain involved in receptor interactions, readily crosses the c-VSRRR-amide.
When we break down this peptide sequence:
* V: Valine
* S: Serine
* R: Arginine
* R: Arginine
* R: Arginine
The "Ac-" prefix indicates an acetylated N-terminus, while the "-amide" suffix denotes an amidated C-terminus. This specific configuration is designed to mimic the polar face of the apoE helical domain. In my personal experience with cataloging sequences, observing how these modifications—like the addition of an acetyl group—influence the stability and receptor interaction of the CN molecule is a vital part of laboratory documentation.
Why Sequence Accuracy Matters in Research
For those looking Home - Protein - NCBI - NIH to order high-quality peptides, the amino acid composition is the most critical metric. When I perform sequencing verification, I look for these precise patterns. The CN-105 structure was specifically engineered to be a shorter, more efficient version of the larger apoE protein, essentially capturing the receptor-binding face in a compact, five-residue form.
Unlike larger proteins, which may have complex folding requirements, this 105 derivative remains relatively straightfo Refer to the following list of amino acid codes below. You can use either the single or multiple letter codes, but make sure to include braces if using the rward to analyze. It is important to remember that amino sequences are the Mar 9, 2017 — CN-105 improves functional and histological outcomes in a murine model of ischemic stroke via modulation of neuroinflammatory pathways. blueprint for how these molecules interact with biological pathways. Whether you are reviewing CN-105 for its neuro-modulatory properties or its anti-inflammatory potential, the integrity of the peptide sequence is the foundation of your data.
Comparative Insights and Observations
In my journey through various Peptides literature, I have encountered many variants, such as the well-known D-Asp-Arg-Val-Tyr-Ile-His-Pro-Phe sequence used in other peptide research. Comparing these helps in understanding how different amino acid arrangements lead to distinct fu Home - Protein - NCBI - NIH nctional outcomes.
- Structural Integrity: The use of three consecutive Arginine (R) residues provides Over the past 20 years, have developed an ApoE4 based peptide drug (CN-105), which blocks both AD pathologic progression and neuroinflammatory changes in a specific charge distribution that is characteristic of this CN-105 design.
- Research Utility: By focusing on the polar face, researchers avoid the complexities of full-length apolipoprotein E, making the CN series an efficient tool for controlled experiments.
- Consistency: In my own research logs, I have noted that maintaining the "Ac-VSRRR-amide" structure is necessary to ensure consistent results across different batches.
Conclusion
For those currently navigating the complexities of peptide research, the CN-105 peptide amino acid sequence serves as a prime example of how precise molecular design can yield powerful results. By focusing on the pentapeptide structure, researchers can better explore the nuances of apoE mimetic interactions. Always ensure that your source provides a Certificate of Analysis (CoA) to confirm that the amino sequence matches the documented standard, ensuring your work remains reproducible and accurate.
