Probable adhesion protein, which mediates homophilic and heterophilic interactions. In contrast to SCARF1, it poorly mediates the binding and degradation of acetylated low density lipoprotein (Ac-LDL) (By similarity). Homophilic and heterophilic interaction via its extracellular domain. Interacts with SCARF1. The heterophilic interaction with SCARF1, which is stronger than the homophilic interaction with itself, is suppressed by the presence of SCARF1 ligand such as Ac-LDL (By similarity). Predominantly expressed in endothelial cells. Expressed in heart, placenta, lung, kidney, spleen, small intestine and ovary. The disease is caused by variants affecting the gene represented in this entry.
