Journal ArticleDOI

CD9, CD63, CD81, and CD82 are components of a surface tetraspan network connected to HLA-DR and VLA integrins

TL;DR: The existence of a tetraspan network which, by connecting several molecules, may organize the positioning of cell surface proteins and play a role in signal transduction, cell adhesion, and motility is suggested.
Journal ArticleDOI

Differential stability of tetraspanin/tetraspanin interactions: role of palmitoylation

TL;DR: The palmitoylation of CD9 did not influence the partition in detergent‐resistant membranes but contributed to the interaction with CD81 and CD53, and the resistance of the CD9/CD81 interaction to EDTA, which disrupts other tetraspanin/tetraspAnin interactions, was entirely dependent on palmitoyslation.
Journal ArticleDOI

The major CD9 and CD81 molecular partner. Identification and characterization of the complexes.

TL;DR: The identification of a protein strongly linked to the tetraspanin web and the production of a specific monoclonal antibody will help to further characterize the role of this “web” under physiological and pathological conditions.
Journal ArticleDOI

Selective tetraspan-integrin complexes (CD81/alpha4beta1, CD151/alpha3beta1, CD151/alpha6beta1) under conditions disrupting tetraspan interactions.

TL;DR: It is shown that another classical mild detergent, digitonin, dissociated most of these associated molecules, including integrins, from the tetraspans CD9, CD37, CD53, CD63, CD82, Co-029, Talla-1 and NAG-2, and a new anti-CD151 monoclonal antibody (mAb) was shown to have a restricted pattern of expression.
Journal ArticleDOI

A physical and functional link between cholesterol and tetraspanins

TL;DR: It is shown that tetraspanins interact with cholesterol as indicated by the precipitation by digitonin, a cholesterol‐precipitating reagent, and the labeling of the tetrascanins CD9, CD81 and CD82 with a photoactivatable cholesterol in vivo.
