Regulation of urokinase receptor proteolytic function by the tetraspanin CD82.
The high affinity interaction between the urokinase-type plasminogen activator (uPA) and its glycolipid-anchored cellular receptor (uPAR) promotes plasminogen activation and the efficient generation of pericellular proteolytic activity. We demonstrate here that expression of the tetraspanin CD82/KAI1 (a tumor metastasis suppressor) leads to a profound effect on uPAR function. Pericellular plasm...
متن کاملClinical significance of KAI1/CD82 protein expression in nasopharyngeal carcinoma
The aim of this study was to investigate KAI1/CD82 protein expression in human nasopharyngeal carcinoma (NPC) cell lines and human NPC tissues. Immunohistochemistry and western blot analysis were used to detect the localization and expression levels of the KAI1/CD82 protein in five human NPC cell lines. Immunohistochemistry was also conducted to detect the expression of the KAI1/CD82 protein in...
متن کاملTetraspanin CD82 regulates compartmentalisation and ligand-induced dimerization of EGFR.
We have previously shown that CD82, a transmembrane protein of the tetraspanin superfamily is associated with EGFR and has a negative effect on EGF-induced signalling (Odintsova, E., Sugiura, T. and Berditchevski, F. (2000) Curr. Biol. 10, 1009-1012). Here we demonstrate that CD82 specifically attenuates ligand-induced dimerization of EGFR. The recombinant soluble large extracellular loop of CD...
متن کاملCD82 metastasis suppressor gene: a potential target for new therapeutics?
The transmembrane glycoprotein CD82 is a member of the tetraspanin protein family and is a metastasis suppressor implicated in biological processes ranging from fusion, adhesion and migration to apoptosis and cell-morphology alterations. Downregulation of CD82 expression is associated with the advanced stages of many human cancers and correlates with the acquisition of metastatic potential. Rec...
متن کاملTetraspanins CD81 and CD82 Facilitate α4β1-Mediated Adhesion of Human Erythroblasts to Vascular Cell Adhesion Molecule-1
The proliferation and terminal differentiation of erythroid progenitors occurs in human bone marrow within erythroblastic islands, specialised structures consisting of a central macrophage surrounded by developing erythroid cells. Many cell-cell and cell-matrix adhesive interactions maintain and regulate the co-ordinated daily production of reticulocytes. Erythroid cells express only one integr...
