Integrin α9β1 is a transmembrane protein belonging to the integrin family. It is widely expressed in airway epithelium, different types of muscle cells, and hepatocytes. In the hematopoietic system, integrin α9β1 is highly expressed on human neutrophils and at low level on monocytes. Multiple ligands have been identified for this integrin including the inducible endothelial counter-receptor, vascular cell adhesion molecule-1 (VCAM-1), the extracellular matrix proteins tenascin C and osteopontin, some members of ADAMs family, coagulation factor XIII, and von Willebrand factor. It has been reported that binding of the α9 cytoplasmic domain to spermidine/spermine N(1)-acetyltransferase (SSAT) mediates α9β1 enhancement of cell migration, mediates adhesion to the extracellular matrix proteins, and is involved in G-CSF signaling. More recently, integrin α9β1 was found on hematopoietic stem and progenitor cells to mediate stem cells adhesion, proliferation, and differentiation.Product Details
