Scientific background

Nectin Cell Adhesion Molecule 4 (nectin-4), also known as Poliovirus Receptor-Related Protein 4 (PVRL4), is a Ca2 + -independent type 1 transmembrane protein that is a member of the immunoglobulin-like adhesion molecules protein family 1.

All nectins (Nectin-1, Nectin-2, Nectin-3, and Nectin-4) share common structure features:  an extracellular region of three Ig-like domains, a transmembrane region, and a cytoplasmic tail region 2.

Nectin-4 interacts with afadin, a protein that has a role in cell-cell adhesion, and with nectin-1, but not with nectin-2 or 3 3.

Nectin-4 was found to be overexpressed in several human cancers, including lung, ovarian, pancreatic, and breast cancer. It was also demonstrated that a soluble form of Nectin-4 is a potential diagnostic marker for several cancers and that knockdown of Nectin-4 inhibits tumor growth and reduces cell-cell contact in certain cancer types 4.

Recently, an antibody-drug conjugate designed for the treatment of cancer expressing Nectin-4 was approved for use in bladder cancer patients.
