?|cl19113: ApoLp-III_like Superfamily (this model, PSSM-Id:267466 is obsolete)
Apolipophorin-III and similar insect proteinsExchangeable apolipoproteins play vital roles in the transport of lipids and lipoprotein metabolism. Apolipophorin III (apoLp-III) assists in the loading of diacylglycerol, generated from triacylglycerol stores in the fat body through the action of adipokinetic hormone, into lipophorin, the hemolymph lipoprotein. ApoLp-III increases the lipid carrying capacity of lipophorin by covering the expanding hydrophobic surface resulting from diacylglycerol uptake. It plays a critical role in the transport of lipids during insect flight, and may also play a role in defense mechanisms and innate immunity.
