Predicted to enable high-density lipoprotein particle receptor activity and identical protein binding activity. Predicted to be involved in endocytosis. Predicted to act upstream of or within cellular response to leukemia inhibitory factor and positive regulation of peptide hormone secretion. Predicted to be located in cytosol and tricellular tight junction. Predicted to be part of protein-containing complex. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 42. Orthologous to human ILDR1 (immunoglobulin like domain containing receptor 1).
