Purity ~90% (SDS-PAGE). May act as a physical homophilic interaction molecule between intestinal epithelial cells (IECs) and intraepithelial lymphocytes (IELs) at the mucosal epithelium for providing immunological barrier as a first line of defense against mucosal infection. Plays a role in embryonic stem cells proliferation and differentiation. Up-regulates the expression of FABP5, MYC and cyclins A and E. Source: Recombinant protein corresponding to aa24-265 from human EPCAM, fused to His-SUMO-Tag at N-terminal, expressed in E. coli. Molecular Weight: ~43.4kD AA
