Membrane glycoproteins of the rat small intestine

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1974
Abstract The glycoprotein and glycolipid content of brush border and submicrosomal membranes from the mucosa of the rat small intestine was investigated. The microsomal preparations were treated to remove the “non-membranous” material before analysis. In all of the membranes nearly 80% of the carbohydrate was associated with the protein fraction, and

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 ...

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.

Glycoproteins of the Synaptosomal Plasma Membrane [PDF]

, 1972
Plasma membranes contain glycoproteins (1–4) which are believed to account for part of the carbohydrate-containing material (heavily stained by the periodic acid-Schiff reaction), coating the outer surface of cells (5). Such coat material is present also in neurons (5), but, in the absence of suitable techniques for isolating highly purified neuronal ...

Reassociation of membrane glycoprotein with intact erythrocytes

Biochemical and Biophysical Research Communications, 1973
Abstract Purified membrane glycoprotein was found to specifically bind to erythrocyte surfaces. (1) The glycoprotein showed over 80-fold greater binding to erythrocytes than did bovine serum albumin; (2) the binding of the glycoprotein was not significantly inhibited by the presence of other proteins even when added in 175-fold greater concentration;

Polymorphisms of Platelet Membrane Glycoproteins

2009
Platelet glycoproteins (GPs) act as membrane receptors. Functions of GPs were well studied in GPIa/IIa (integrin α2β1), GPIb/IX/V, GPIIb/IIIa (integrin αIIbβ3), and GPVI. Each GP has a different role in the processes of physiological hemostasis and thrombus formation, such as platelet adhesion to the subendothelial matrix, firm adhesion with subsequent

The Structure and Biosynthesis of Membrane Glycoproteins

1978
Publisher Summary Glycoproteins are a large and heterogeneous group of macromolecules and serve a variety of different functions. This chapter reviews the structure and biosynthesis of these membrane-bound glycoproteins. The carbohydrate of the cell surface membrane is always oriented toward the external environment; this fact and the analogous ...
