Isolation of a concanavalin A receptor from mouse L cells

Biochemistry, 1975
A cell surface glycoprotein receptor for concanavalin A (Con A) has been isolated from mouse L cells. The isolation procedure involved dissolving whole L cells in 0.3 M lithium diiodosalicylate and extracting with aqueous phenol. The Con A receptor, which was found in the aqueous phase of this extract, was further purified by affinity chromatography on

Are Concanavalin A Receptor Sites Mediators of Cell-Cell Adhesion?

Nature New Biology, 1973
THE identity of the chemical sites that mediate adhesions between tissue cells remains to be established. Attractive candidates for this role include carbohydrate-containing groups which have in recent years been shown to be common structural constituents of animal cell membranes1.

Dynamic state of concanavalin a receptor interactions on fibroblast surfaces

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1975
Cultured normal and transformed fibroblasts were treated "in situ" by the concanavalin A-peroxidase labelling technique. It is known that peroxidase recognizes only a fraction of the bound lectin depending on the cell type. Kinetics studies revealed that 80 to 95 percent of the peroxidase and only 10 percent of the lectin are released from the cell ...

Interaction between the hepatic growth hormone receptor and concanavalin A

Molecular and Cellular Endocrinology, 1979
The interaction between the plant lectin concanavalin A (Con A) and hepatic receptors for human growth hormone (GH) has been studied in particulate and soluble microsomal membrane preparations from rabbit and rat liver. Con A shows a dose-dependent, partial (30%) inhibition of 125I-human GH binding which is reversed by the Con A competitor, alpha ...

CONCANAVALIN A SURFACE RECEPTORS AND CYTOPLASMIC ACTIN IN CELL ADHESION

Australian Journal of Experimental Biology and Medical Science, 1979
SummaryA double immunofluorescence staining technique to locate concanavalin A (Con A) surface receptors and cytoplasmic actin in the same cell was applied to monolayer cultures of rat foetal fibroblasts during cell detachment induced by trypsin and during cell attachment to a glass substratum.

EGF receptor‐mediated signals are differentially modulated by concanavalin A

Journal of Cellular Physiology, 1995
AbstractNIH 3T3 cells expressing hgh levels of the human epidermal growth factor (EGF) receptor were used to examine the effects of the lectin concanavalin A (Con A) on EGF‐mediated signaling events. Proliferation of NIH 3T3 cells expressing high levels of the human EGF receptor was inhibited in a dose‐dependent manner by Con A. At the same time, Con A

Modifications of the thymocyte membrane during redistribution of concanavalin A receptors

European Journal of Immunology, 1976
AbstractThe modifications of the thymocyte membrane which are induced by concanavalin A (Con A) were studied by means of the variation of electro phoretic mobility which the lectin induces on the cell. The electrophoretic mobility of thymocytes is increased when Con A is used under conditions expected to induce a cap formation and the subsequent ...

Relationship between membrane fluidity and capping of receptors for concanavalin A

Canadian Journal of Biochemistry, 1980
The activities of a range of phenylalaninol-related compounds on capping of concanavalin A and induction of rounding of Chinese hamster ovary tsHl cells, as well as on the fluidity of phosphatidylcholine–cholesterol (1:1) liposomes, have been examined.

Effect of concanavalin A dose, unbound concanavalin A, temperature, ca2+ and mg2+, and vinblastine on capping of concanavalin A receptors of human peripheral blood lymphocytes

Journal of Cell Science, 1979
ABSTRACT The capping of Concanavalin A (Con A) receptors induced by Con A was studied using human peripheral blood lymphocytes. The effects of Con A dose (5–100 μg/ml), pretreatment at 4 °C, unbound Con A, extracellular Ca2+ and Mg2+ and vinblastine were evaluated using Con A-horseradish peroxidase and electron microscopy.

[Redistribution of concanavalin A receptors on the thrombocyte surface].

Tsitologiia, 1982
Using the indirect immunofluorescence method, it has been shown for the first time that concanavalin A receptors can undergo a redistribution over the surface of platelets spread on the substrate. The distribution of receptors in the intact cells is diffuse and random.
