  1. Resource Description
    "The class B, type I scavenger receptor (Srb1 or Scarb1) is a cell surface HDL receptor that can recognize the apolipoproteins on the surface of the HDL particle. It plays a key role in determining the levels of plasma lipoprotein cholesterol (primarily HDL) and the accumulation of cholesterol stores in the adrenal gland.In this strain plasma cholesterol (primarily HDL) concentrations increase by 125% in homozygotes and 31% in heterozygotes, as compared to wild type controls. Also, cholesterol levels in adrenal tissue in homozygous and heterozygous mutants decrease by 72% and 42% respectively, relative to wild type controls. The plasma concentration of Apoa-I, the major protein in HDL, is unchanged in mutant animals, relative to wild type controls.Homozygous females are infertile; homozygous males are fertile. Please note that the donating investigator reports that the number of homozygotes resulting from a cross between heterozygotes is significantly lower than what the expected Mendelian ratio would predict."
