Two independent lipoprotein receptors on hepatic membranes of dog, swine, and man. Apo-B,E and apo-E receptors.
We have reported previously that canine livers possess two distinct lipoprotein receptors, an apoprotein (apo)-B,E receptor capable of binding the apo-B-containing low density lipoproteins (LDL) and the apo-E-containing cholesterol-induced high density lipoproteins (HDLc), and an apo-E receptor capable of binding apo-E HDLc but not LDL. Both the apo-B,E and apo-E receptors were found on the liv...
متن کاملApo A-i and Apo E Interaction: beyond Lipoproteins
Apolipoproteins (Apo) A-I, A-II, A-IV, and E possess repeated amphipathic helical regions with the same genomic structure and are members of a multigene family that probably evolved from a common ancestral gene [1]. These apolipoproteins play pivotal roles in lipid transport and lipoprotein metabolism, and their carboxyl-terminal domain is critical for lipid binding [2]. The purpose of this com...
متن کاملIsolation and characterization of the apolipoprotein E receptor from canine and human liver.
Previous results have demonstrated that liver membranes possess two distinct lipoprotein receptors: a low density lipoprotein (LDL) receptor that binds lipoproteins containing either apolipoprotein (apo-) B or apo-E, and an apo-E-specific receptor that binds apo-E-containing lipoproteins, but not the apo-B-containing LDL. This study reports the isolation and purification of apo-B,E(LDL) and apo...
متن کاملStudy of the Binding of Iron and Indium to Human Serum Apo-Transferrin
Indium is a heavy metal belonging to group IIIa. It is believed that indium may interfere with iron metabolism from the sites of absorption, transportation, utilization and storage in the cells. The present investigation was established to study and compare the binding of iron and indium to human apo-transferrin (apo-tf). Pure human apo-tf was used and the binding activity of iron and indium, a...
متن کاملRegulation of hepatic lipoprotein receptors in the dog. Rapid regulation of apolipoprotein B,E receptors, but not of apolipoprotein E receptors, by intestinal lipoproteins and bile acids.
Two distinct lipoprotein receptors can be expressed in the dog liver. One is the apolipoprotein (apo-) B,E receptor. This receptor binds apo-B-containing low density lipoproteins (LDL), as well as apo-E-containing lipoproteins, such as the cholesterol-induced high density lipoproteins (HDL(c)). The second hepatic lipoprotein receptor is the apo-E receptor. It binds apo-E HDL(c) and chylomicron ...
