Interaction of an insect lipoprotein with its binding site at the fat body.
A single type of high density lipoprotein (HDLp) binding sites is present at intact fat body tissue and in fat body membranes of larval and adult locusts. HDLp is bound with high affinity (Kd approximately 10(-7) M). This interaction does not require divalent cations and is heat-labile because heat-treatment of fat body membranes results in a substantial reduction of the maximal binding capacit...
متن کاملLipophorin receptor-mediated lipoprotein endocytosis in insect fat body cells.
High-density lipophorin (HDLp) in the circulation of insects is able to selectively deliver lipids to target tissues in a nonendocytic manner. In Locusta migratoria, a member of the LDL receptor family has been identified and shown to mediate endocytosis of HDLp in mammalian cells transfected with the cDNA of this receptor. This insect lipophorin receptor (iLR) is temporally expressed in fat bo...

A lipoprotein receptor has been purified from the fat body of Manduca sexta larvae. The purification involves solubilization of membrane proteins in detergent, DEAE-, and hydroxyapatite chromatography, affinity chromatography on a concanavalin A column, and affinity chromatography on a lipoprotein-sepharose column. An overall purification of 220-fold from the solubilized membranes was achieved....
