Mapping of the Gene for High-Density Lipoprotein Binding Protein (Hdlbp) to Proximal Mouse Chromosome 1

Abstract

HDL binding protein (HBP) is a 150-kDa glycoprotein that is processed to smaller forms (105-110 kDa) that bind HDL. In vitro studies have shown that HBP protein mass and mRNA levels increase in cells overloaded with cholesterol, suggesting that this protein plays a role in HDL-mediated removal of cholesterol from cells, a process that may underlie the anti-atherogenic effects of HDL. The cDNA for human HBP has been identified and the gene (HDLBP) localized to chromosome 2q37. To test whether the HDL binding protein gene underlies any mutations in the mouse or whether it contributes to multigenic variations contributing to lipoprotein metabolism between inbred mouse strains, we report the chromosomal mapping in mouse for the mouse HBP gene (Hdlbp).
