Enables high-density lipoprotein particle receptor activity. Acts upstream of or within cellular response to leukemia inhibitory factor and positive regulation of peptide hormone secretion. Located in plasma membrane and tricellular tight junction. Is expressed in olfactory epithelium. Used to study autosomal recessive nonsyndromic deafness 42. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 42. Orthologous to human ILDR1 (immunoglobulin like domain containing receptor 1).
