Bio-activity
Measured by the ability of the immobilized protein to support the adhesion of NIH-3T3 mouse embryonic fibroblast cells. When cells are added to EpCAM-His coated plates (1.25μg/mL, 100μL/well), approximately>40% will adhere specifically after 30 minutes a
Molecular Mass
Recombinant Human EpCAM consists of 253 amino acids after removal of the signal peptide and has a calculated molecular mass of 29 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh EpCAM is approximately 36 kDa due to glycosylation.
Background
Induces cartilage and bone formation (PubMed:3201241). Stimulates the differentiation of myoblasts into osteoblasts via the EIF2AK3-EIF2A- ATF4 pathway. BMP2 activation of EIF2AK3 stimulates phosphorylation of EIF2A which leads to increased expression of ATF4 which plays a central role in osteoblast differentiation. In addition stimulates TMEM119, which upregulates the expression of ATF4 (PubMed:24362451).
