NHE2 and NHE3 are human and rabbit intestinal brush-border proteins.

American Journal of Physiology, 1996
Rabbit NHE2 and NHE3 are two epithelial isoform Na+/H+ exchangers (NHE), the messages for which are found predominantly and entirely, respectively, in renal, intestinal, and gastric mucosa.

The Enterocyte and its Brush Border

1991
The close relationship between physical structure and physiological function is nowhere more apparent than in the small intestine. The mucosal surface is lined with a virtually continuous epithelial monolayer of columnar enterocytes that constitute the primary cellular barrier between the intestinal lumen and the internal milieu.

Phosphate transport in intestinal brush-border membrane

Journal of Bioenergetics and Biomembranes, 1988
In the small intestine of the rabbit the process of Na+-dependent uptake of phosphate occurs only at the brush-border of duodenal enterocytes. Li+ can replace Na+. The process is activated when either K+, Cs+, Rb+, or choline is present in the intravesicular space.

Proteome of murine jejunal brush border membrane vesicles.

Journal of Proteome Research, 2007
The first detailed description of the proteome of the mouse jejunal brush border membrane vesicle is presented here. This was obtained by a combination of purification via divalent (Mg2+) cation precipitation starting with isolated cells plus strong ...

GLYCOPROTEINS OF THE BRUSH BORDER MEMBRANE OF MOUSE DUODENUM

Australian Journal of Experimental Biology and Medical Science, 1978
SummaryQualitative and quantitative chemical analyses have been made of the carbohydrate and protein moieties of the glycoproteins in purified mouse duodenal brash border membranes. Solubilized membrane protein was electro‐phoresed on S.D.S.‐polyacrylamide gels and glycoproteins were subsequently identified by periodate‐Schiff staining.

Intestinal alkaline phosphatase: selective endocytosis from the enterocyte brush border during fat absorption.

American Journal of Physiology - Gastrointestinal and Liver Physiology, 2007
Absorption of dietary fat in the small intestine is accompanied by a rise of intestinal alkaline phosphatase (IAP) in the serum and of secretion of IAP-containing surfactant-like particles from the enterocytes.

Purification of brush border membrane by thiocyanate treatment

Analytical Biochemistry, 1983
Rat small intestinal brush border membranes are purified from brush borders by homogenization in relatively high concentrations of thiocyanate salts (0.56 M LiSCN, 0.41 M NaSCN, or 0.52 M KSCN), removal of this salt, and differential centrifugation to separate cytoskeletal material from membranes.

Dimeric Assembly of Enterocyte Brush Border Enzymes

Biochemistry, 1994
The noncovalent, dimeric assembly of small intestinal brush border enzymes was studied by sedimentation analysis in density gradients of extracts of pulse-labeled pig jejunal mucosal explants. Like aminopeptidase N (EC 3.4.11.2), sucrase-isomaltase (EC 3.2.1.48-10), aminopeptidase A (EC 3.4.11.7), and dipeptidyl peptidase IV (EC 3.4.14.5) were all ...

Cytochromes in the rat kidney brush border membrane

Biochemical and Biophysical Research Communications, 1978
Abstract Spectrophotometric studies of the brush border membrane fraction of the rat kidney as compared with those of its mitochondria and microsomes were carried out. Occurrence of cytochromes has been demonstrated in the brush border membranes. Either in the brush border membranes and in the mitochondria evidence for the presence of cytochromes of ...
