Enables low-density lipoprotein particle receptor activity. Predicted to be involved in several processes, including inflammatory response; leukocyte cell-cell adhesion; and lipoprotein metabolic process. Predicted to act upstream of or within cell adhesion and immune system process. Predicted to be located in nucleoplasm. Predicted to be part of receptor complex. Predicted to be active in plasma membrane. Is expressed in blood vessel; embryo; heart; and primitive ventricle. Human ortholog(s) of this gene implicated in cerebral amyloid angiopathy; coronary artery disease; and myocardial infarction. Orthologous to human OLR1 (oxidized low density lipoprotein receptor 1).
