Abstract

Background: Nectin is a Ca2+-independent immunoglobulin-like cell-cell adhesion molecule at the E-cadherin-based cell-cell adherens junctions (AJs), and comprises a family consisting of four members, nectin-1, -2, -3, and -4. Nectin and E-cadherin are associated with afadin and α-catenin, actin filament (F-actin)-binding proteins connecting respective adhesion molecules to the actin cytoskeleton, but the role of nectin in the formation of the E-cadherin-based cell-cell AJs has not yet been fully understood. To obtain evidence for this role of nectin, we attempted to develop an antagonist and/or agonist of nectin. Results: We made a recombinant extracellular fragment of nectin-3 (Nef-3). Nef-3 trans-interacted with cellular nectin-1 and thereby diminished the formation of the nectin-1-based cell-cell adhesion. This resulted in a reduction of the formation of the E-cadherin-based cell-cell adhesion in L fibroblasts stably expressing both exogenous nectin-1α and E-cadherin (nectin-1-EL cells) and MDCK cells stably expressing exogenous nectin-1α (nectin-1-MDCK cells). This antagonistic effect of Nef-3 was also observed in L cells stably expressing exogenous E-cadherin alone (EL cells) and wild-type MDCK cells. Conversely, Nef-3 coated on microbeads first recruited the nectin-afadin complex and then the E-cadherin-catenin complex to the bead-cell contact sites in nectin-1-EL and nectin-1-MDCK cells. Conclusion: These results suggest that nectin is necessary and sufficient for the recruitment of E-cadherin to the nectin-based cell-cell adhesion sites and involved in the formation of E-cadherin-based cell-cell AJs.
