Binds and internalizes TRL when out of the context of the macrophage. May provide essential lipids to reticuloendothelial cells. Could also be involved in foam cell formation with elevated TRL and remnant lipoprotein (RLP). Mediates the rapid high-affinity uptake of chylomicrons (CM), HTG- VLDL, and trypsinized (tryp) VLDL devoid of APOE in vitro in macrophages. {ECO:0000269|PubMed:10852956, ECO:0000269|PubMed:15591219, ECO:0000269|PubMed:9633939}.
