Recombinant Human E-Selectin (CD62E)-Fc Chimeric (carrier-free)
Description
E-Selectin, an adhesion molecule, belongs to the selectin/LECAM family. E-Selectin consists of one Lectin domain and several EGF-like repeats, which are followed by a transmembrane region and a short cytoplasmic tail of 32 amino acids. E-Selectin is only expressed in endothelial cells. Upon activation by TNF-α, IL-1, and LPS, E-Selectin is upregulated at the transcriptional level and reaches the maximal peak at the cell surface in three to six hours. Then the expression level returns to the baseline after 16 to 24 hours. In contrast with P-Selectin, IL-4 suppresses the expression of E-Selectin. E-Selectin binds to its ligand ESL-1, which is a glycoprotein that is expressed in neutrophils. In addition, E-Selectin binds to PSGL-1, which interacts with P-Selectin as well. The interactions between E-Selectin and its ligands initiate cell contact and leukocyte rolling on endothelial cells’ surfaces during inflammation. E-Selectin’s expression is elevated in several types of cancer cells and contributes to cancer metastasis. Thus, in Selectin-deficient mice, metastatic breast cancer cell homing to the lung vasculature is reduced.
