Recombinant human NECTIN4 protein is a mammalian cell-expressed partial length protein. Molecularly, this NECTIN4 protein is characterized by an N-terminal linker, internal human NECTIN4 DNA fragment (Gly32-Ser349), and a 10xHis tag at the C-terminus. Its purity is greater than 95% measured by SDS-PAGE. It has an apparent molecular weight of approximately 40 kDa on the gel. This slightly higher molecular mass results from glycosylation. This NECTIN4 protein contains low endotoxin, less than 1.0 EU/ug of the protein determined by the LAL method. Through a functional ELISA, this NECTIN4 protein has been validated to be active. It can bind to the anti-NECTIN4 antibody with an EC50 of 0.6029-0.7837 ng/mL.

NECTIN4 participates in the intercellular connection and controls cell activities including cellular polarization, differentiation, motility, proliferation, and survival. Evidence has shown that NECTIN4 is overexpressed in multiple tumor cells but with a low expression in adult healthy tissues. NECTIN4, therefore, becomes a promising target for the diagnosis, prognosis, and treatment of many cancers. So far, a drug that combined the NECTIN4 antibody with MMAE has been developed and approved by FDA in December 2019 for the treatment of urothelial carcinoma.

Target Background

Seems to be involved in cell adhesion through trans-homophilic and -heterophilic interactions, the latter including specifically interactions with NECTIN1. Does not act as receptor for alpha-herpesvirus entry into cells.; (Microbial infection) Acts as a receptor for measles virus.
