When exploring the world of biochemistry and molecular research, the VIP peptide sequence often emerges as a primary point of interest. As someone who has spent considerable time analyzing the structural characteristics of various molecules, I have found the Vasoactive Intestinal Polypeptide (VIP) to be one of The vasoactive intestinalpeptide(VIP) gene is mapped to human chromosome 6q25.2.

The Structural Foundation
At its core, VIP is a peptide of 28 amino acid residues. This specific arrangement is what defines its functional identity. When we look at the H-His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg sequence—often represented in its full 28-amino acid form—we are looking at a molecule that is remarkably stable.
From my personal review of laboratory data, it is important to note that VIP is a neuropeptide that belongs to the glucagon/secretin superfamily. This classification is vital for those interested in the ligand-receptor dynamics of class II G protein-coupled receptors. A key detail often discussed in research circles is that VIP has 67% sequence homology with PACAP-27, and it shares roughly 68 percent sequence homology with pituitary adenylyl cyclase-activating polypeptides. This structural similarity is why researchers often study them in tandem.
Key Characteristics and Observations
In my experience analyzing molecular data, the following details are essential for anyone attempting to understand this polypeptide:
* Origin: VIP was first isolated and sequenced from pig small intestine, which paved the way for modern mapping of the DNA sequences coding for the VIP and its precursor molecules.
* Conservation: The amino acid order is identical in humans, bovine, porcine, and rat models. This evolutionary conservation underscores its fundamental role in biological systems.
* Synthesis: VIP is synthesized from a peptide precurso Aug 1, 2013—VIP has 67% sequence homology with PACAP-27. The sequence for VIP is identical in the human, bovine, porcine and rat. Mutations.

Practical Considerations for Researchers
When sourcing or reviewing data on VIP (Vasoactive Intestinal Peptide), researchers often encounter specific identifiers. For instance, the neuroblastoma VIP-cDNA sequence is a common reference point for those examining gene expression. Furthermore, the sequence is often cited in studies regarding its interaction with VPAC1 and VPAC2 receptors.
If you are looking to order materials for analytical purposes, you will frequently see the shorthand His-Ser-Asp-Ala used to denote the N-terminal start of the chain. Always ensure that the purity and the analytical verification (such as mass spectrometry confirming the 3323.77 Da molecular weight) align with your specific project requirements.
