Membrane glycoprotein choreography

Current Biology, 1991
It is generally understood that interactions of the integral plasma membrane proteins with the underlying cytoskeleton are responsible for many cellular processes, including cell motility, cell adhesion, cell polarity, and membrane internalization. Although a few membranecytoskeletal interactions have been defined at the molecular level, there has been

Proteins and glycoproteins of the erythrocyte membrane

Archives of Biochemistry and Biophysics, 1972
Abstract Erythrocyte membranes from several species were prepared by three different methods of hypotonic hemolysis and examined for variations in protein and glycoprotein content by acrylamide gel electrophoresis in sodium dodecyl sulfate. Significant variations were noted in morphology of the membranes prepared by the different methods without ...

Dimerization of the P-glycoprotein in membranes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1990
Plasma membranes from a CHO cell line, CHRC5, which exhibits multidrug resistance was studied using radiation inactivation analysis. The P-glycoprotein content of the membrane was determined by Western blots. Irradiation resulted in the loss of P-glycoprotein.

Identification of glycoproteins on nitrocellulose membranes and gels

Molecular Biotechnology, 1996
In this article we describe a procedure for the detection of glycoproteins on gels employing the periodic acid-Schiff's reagent. In addition, a number of staining protocols and direct binding ELISA, employing antibodies and lectins, are described for the identification and quantitation of glycoproteins after their immobilization by dot, slot, or ...

Characterization of a Sperm Membrane Glycoprotein

1986
The sperm plasma membrane has been the object of intense research activity in recent years (Moore, 1985). As a consequence, a large amount of data has accumulated, particularly on its structure and biochemistry, that is now beginning to yield information that may be generally useful in cell biology.

Biosynthesis of membrane and a membrane glycoprotein in Tetrahymena pyriformis

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
Abstract 1. 1. A membrane glycoprotein was isolated from Tetrahymena surface membrane with properties similar to mammalian erythrocyte glycoprotein. 2. 2. This membrane glycoprotein had a specific acitivity less than whole membrane at various time intervals up to 40 hr. 3. 3.

Platelet Membrane Glycoproteins

2017
Platelets are small anucleate blood cells that are produced in the bone marrow from the cytoplasm of megakaryocytes. Circulating platelets are essential for primary hemostasis and also involved in pathological thrombosis. For the platelet hemostatic functions, platelet surface membrane glycoproteins are crucial to form platelet-subendothelial matrix ...

Circular dichroism of erythrocyte membrane glycoproteins

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1975
The circular dichroism spectra were obtained for purified equine, human and bovine membrane glycoproteins, which have 40, 55 and 70% carbohydrate, respectively. The spectra in aqueous buffer show similar shapes, maxima and minima but somewhat different peak amplitudes. Analysis of the spectra indicated that the glycoproteins can be pictured as existing

Reprocessing of Membrane Glycoproteins

1994
Newly synthesized surface glycoproteins undergo extensive processing of their N-linked oligosaccharides during transport from the endoplasmic reticulum to the cell surface (for review Kornfeld and Kornfeld 1985). The fundamental processing reactions include removal of glucose and mannose residues from Glc3Man9GlcNAc2 by glucosidases I and II and ...

Glycoprotein Membrane Enzymes

1978
Publisher Summary This chapter discusses glycoprotein membrane enzymes individually in a sequence concentrating initially on the enzymes of general distribution, followed by brush border hydrolases and acid hydrolases of the lysosome. The chapter concentrates on two aspects of glycoprotein membrane enzymes: (1) the characterization, membrane ...
