Anti-Mouse Nectin-3, clone 103-A1 (Monoclonal) [Rat]

MON4000 recognizes mouse nectin-3. Nectin-3 is a 83 kDa type I transmembrane glycoprotein. Nectin, originally isolated as poliovirus receptor-related protein (PRR), is a cell-cell adhesion molecule of the immunoglobulin supergene family. Nectins are calcium independent immunoglobulin-like cell-cell adhesion molecules consisting of four members, nectin 1-4. Nectins homophilically and heterophilically trans-interact to form a variety of cell-cell junctions, including cadherin-based adherens junctions in epithelial cells and fibroblasts in culture, synaptic junctions in neurons, and Sertoli cell-spermatid junctions in testis, in cooperation with, or independently of, cadherins. Both nectin-2 and nectin-3 are ubiquitously expressed, whereas nectin-1 is abundantly expressed in brain. Nectin-2 and -3 are expressed in cells where cadherin is not expressed, such as blood cells and spermatids. All members of the nectin family have two or three splice variants. Protein function: Plays a role in cell-cell adhesion through heterophilic trans-interactions with nectins-like or other nectins, such as trans- interaction with NECTIN2 at Sertoli-spermatid junctions. Trans- interaction with PVR induces activation of CDC42 and RAC small G proteins through common signaling molecules such as SRC and RAP1. Also involved in the formation of cell-cell junctions, including adherens junctions and synapses. Induces endocytosis-mediated down-regulation of PVR from the cell surface, resulting in reduction of cell movement and proliferation. Plays a role in the morphology of the ciliary body.
