DESCRIPTION

Also known as CXAR_HUMAN, CXADR, CAR. Component of the epithelial apical junction complex that may function as a homophilic cell adhesion molecule and is essential for tight junction integrity. Also involved in transepithelial migration of leukocytes through adhesive interactions with JAML a transmembrane protein of the plasma membrane of leukocytes. The interaction between both receptors also mediates the activation of gamma-delta T-cells, a subpopulation of T-cells residing in epithelia and involved in tissue homeostasis and repair. Upon epithelial CXADR-binding, JAML induces downstream cell signaling events in gamma-delta T-cells through PI3-kinase and MAP kinases. It results in proliferation and production of cytokines and growth factors by T-cells that in turn stimulate epithelial tissues repair., (Microbial infection) Acts as a receptor for adenovirus type C., (Microbial infection) Acts as a receptor for Coxsackievirus B1 to B6. Monomer. May form homodimer. Interacts with LNX, MAGI1, DLG4, PRKCABP, TJP1 and CTNNB1. Interacts with MPDZ; recruits MPDZ to intercellular contact sites. Interacts with JAML (homodimeric form). Secreted isoform 3, isoform 4 and isoform 5 can interact with the extracellular domain of the receptor.
