Molecular Characterization: ITGB1(Gln21-Asp728) hFc(Glu99-Ala330)Molecular weight: The protein has a predicted molecular mass of 104.5 kDa after removal of the signal peptide. The apparent molecular mass of ITGB1-hFc is approximately 130-250 kDa due to glycosylation.Description: Recombinant human ITGB1 protein with C-terminal human Fc tagIntegrins are heterodimeric proteins made up of alpha and beta subunits. At least 18 alpha and 8 beta subunits have been described in mammals. Integrin family members are membrane receptors involved in cell adhesion and recognition in a variety of processes including embryogenesis, hemostasis, tissue repair, immune response and metastatic diffusion of tumor cells. This gene encodes a beta subunit. Multiple alternatively spliced transcript variants which encode different protein isoforms have been found for this gene.
