In the specialized field of biochemic Target: E-selectin (CHEMBL3890) - ChEMBL al research, the interaction between cell adhesion molecules and specific ligands remains a cornerstone of study. One of the most intriguing areas of investigat by N Milošević · 2025 · Cited by 2 — We hypothesized that a synthetic polymer presenting multiple copies of the high-affinity E-selecting binding peptide (P-Esbp) could block E- ion involves the E selectin binding peptide, a synthetic tool designed to interact with the Selectin E (also known as CD62E) protein. As an enthusiast following advancements in molecular biology, I by MN Fukuda · 2000 · Cited by 248 — These peptides, enriched for their binding to anti-Lewis A antibody, were found to bind to E-, P- and L-selectins in a calcium-dependent manner. have found the precision of these peptides to be a fascinating example of how targeted synthetic chemistry can mimic natural biological processes.
The Role of E-Selectin in Cellular Adhesion
To understand the utility of these peptides, one must first look at the protein itself. E-selectin is a 115 kDa type I transmembrane protein that plays a critical role in the vascular endothelium. Often described as a cell-surface glycoprotein having a role in immunoadhesion, it serves as a bridge for cells under specific physiological conditions.
Researchers categorize this as an inducible cell adhesion molecule, meaning its expression is not constant; rather, E-selectin is inducibly expressed by cytokines on the surface of activated endothelial cells. Because E-selectin is exclusively expressed in endothelial cells following cytokine stimulation, it acts as a unique marker for identifying active vascular sites.
The Function of E Selectin Binding Peptide
The E selectin binding peptide—often referred to in literature as Esbp—is engineered to target this specific protein. These peptides are designed with high specificity, and it is scientifically significant that several of these peptides bind with Kd values in the low nanomolar range. This high affinity allows for precise interaction, which is vital for studies focusing on molecular recognition.
Many of these synthetic constructs function by mimicking the native ligands of the selectin family, such as the sialyl Lewis X (sLex) tetrasaccharide. By acting as a binding peptide, these molecules can effectively occupy the lectin domain of the protein. This is particularly relevant because Selectins are ke E-selectin mediates the adhesion of tumor cells to endothelial cells, by binding to E-selectin ligands expressed by neutrophils, monocytes, eosinophils, memory- y to mediating interactions involved in cellular adhesion and migration.
Structural and Technical Specifications
When analyzing the E-Selectin/CD62E protein, we observe a complex structure. As a 107 – 115 kDa cell surface glycoprotein, it possesses a distinct architecture that facilitates its function.
* Protein Classification: It is recognized as a type I transmembrane glycoprotein expressed on endothelial cells.
* Binding Mechanisms: The interaction is often calcium-dependent, a common feature among Selectin family members, including L-selectin and P-selectin.
* Biological Context: The E-Selectin Protein Function is centered on the tethering and rolling of cells along the vessel wall. It is well-documented that E-selectin mediates the adhesion of tumor cells to endothelial cells, a process that has spurred significant interest in developing conjugates that can navigate these pathways.
Why These Peptides Matter
The study of these peptides is not merely theoretical. Because E-selectin is a cell-adhesion molecule of the vascular endothelium, finding ways to modulate its activity is a major objective in biotechnology. Whether exploring E-selectin, a lectin expressed by endothelial cells that bind by CL Martens · 1995 · Cited by 193 — E-selectin is an inducible cell adhesion molecule which mediates rolling of neutrophils on the endothelium, an early event in the s to specific carbohydrates, or observing how E-selectin is an inducible cell adhesion molecule, the Cell-surface glycoprotein having a role in immunoadhesion. Mediates in the adhesion of blood neutrophils in cytokine-activated endothelium through interaction goal remains the same: to utilize these high-affinity tools for more accurate molecular tracking and interaction studies.
For those interested in the Jan 16, 2020 — Selectins are key to mediating interactions involved in cellular adhesion and migration, underlying processes such as immune responses, terminology, the EMBL database and other resources provide exhaustive data on the gene (SELE) and its corresponding protein. Whether you are looking fo Targeted Polymer-Peptide Conjugates for E-Selectin r E selectin binding peptide for laboratory experiments or simply researching the mechanics of E and selectin interactions, the current body of work highlights the incredible potential of synthetic peptides in understanding the complex landscape of cell adhesion.
