Predicted to enable chloride channel activity and lipid binding activity. Predicted to be located in extracellular space and intracellular membrane-bounded organelle. Predicted to be part of high-density lipoprotein particle and very-low-density lipoprotein particle. Is expressed in ductus deferens and testis. Human ortholog(s) of this gene implicated in focal segmental glomerulosclerosis and schizophrenia. Orthologous to several human genes including APOL1 (apolipoprotein L1); APOL2 (apolipoprotein L2); and APOL3 (apolipoprotein L3). [provided by Alliance of Genome Resources, Apr 2022]
