Apolipoprotein E (ApoE) is a 34‐kDa cholesterol transport protein that also possesses immunomodulatory properties. In this study, we demonstrate that ApoE initiates a signaling cascade in murine peritoneal macrophages that leads to increased production of inositol triphosphate with mobilization of intracellular Ca2+ stores. This cascade is inhibited by pretreatment with receptor‐associated protein and Ni2+, and it is mediated by a pertussis toxin‐sensitive G protein. These properties are characteristic of signal transduction induced via ligand binding to the cellular receptor, lipoprotein receptor‐related protein. A peptide derived from the receptor‐binding region of ApoE also initiates signal transduction in a manner similar to that of the intact protein, suggesting that this isolated region is sufficient for signal transduction. The ApoE‐mimetic peptide competed for binding with the intact protein, confirming that they both interact with the same site. ApoE‐dependent signal transduction might play a role in mediating the functional properties of this lipoprotein.
