Integrin, beta7 (Integrin BetaP, M290 IEL Ag)

Human Integrin Beta7 (also Integrin BetaP and M290 IEL Ag) is a 120kD member of the Integrin beta chain family of molecules. It is a type I transmembrane glycoprotein that contains a 704 amino acid (aa) extracellular domain (ECD) (aa20-723) and a 52aa cytoplasmic tail. The ECD contains one von Willebrand factor A domain (aa150-389) and four cysteine-rich EGF-like repeats. One splice variant exists that shows a deletion of aa501-648. Integrin Beta7 forms a nondisulfide linked heterodimer with alpha4 and alphaE integrins. Alpha4Beta7 binds fibronectin, VCAM-1 and MADCAM1, while alphaEBeta7 binds E-cadherin. The ECD of human Beta7 is 87% aa identical to the ECD of mouse Beta7.\n\nApplications: \nSuitable for use in Direct ELISA, Western Blot and Flow Cytometry.
