Human Nectin-3 is a type 1 integral membrane glycoprotein that can form a homo-cis dimer on the cell membrane. The recombinant Nectin-3 dimer protein (CSP-25196-03) is a cis-homodimer (cis-dimer) and contains a Nectin-3 extracellular domain (UniProt# Q9NQS3, amino acids Gly58-Thr404) fused with a proprietary dimer motif followed by a tandem His-Avi tag at the C-terminus. This dimeric protein is expressed in HEK293T cells. The recombinant human Nectin-3 dimer protein is bioactive and can bind to Nectin-1. It also binds Nectin-3-specific antibodies. This Nectin-3 dimer can be used as an antigen for in vitro assays and antibody screening, and as an immunogen for immunization to generate antibodies targeting more conformational epitopes.

Protein Name: Nectin-3

UniProt #: 1: Q9NQS3

Predicted Molecular Weight: 96 kDa

SDS PAGE Molecular Weight: The migration range of the heterodimer protein with glycosylation under non-reducing condition is ~190 kDa on SDS PAGE.

Protein Construct: Nectin-3 dimer protein contains a Nectin-3 extracellular domainfused with a proprietary cis-dimer motif followed by a tandem His-Avi tag at the C-terminus.

Background

Human Nectin-3 is a type 1 integral membrane glycoprotein that can form a homo-cis dimer on the cell membrane. Nectin-3 is also known as poliovirus receptor-related 3 (PVRL3) and cluster of differentiation 113 (CD113). Nectin-3 contains an extracellular domain with three immunoglobulin-like (Ig-like) domains. Nectin-3 interacts with Nectin-1. Nectin-1 and Nectin-3 are expressed in neuronal tissue and unlike many other cellular adhesion molecules, they do not distribute evenly. Nectin-3 is primarily found on the dendritic side and Nectin-1 is primarily found on the axonal side. The interaction of Nectin-1 with Nectin-3 has been found to be essential for proper morphogenesis of the eye. Additionally, Nectin-3 is highly expressed in epithelial cancer cells of 80% of patients with human lung adenocarcinoma. Therefore, a recombinant protein mimicking the Nectin-3 dimer conformation can be crucial for cancer therapeutic discovery.
