This gene is a member of the apolipoprotein L gene family and protein in this family are lipid-binding proteins. This gene encodes a 37.1 kDa protein and The protein sequence contains 337bp. Localization of this protein is mainly found in the cytosol, nucleoplasm and additionally, it is also seen in the Nuclear bodies.[8] The involvement of this gene may affect in the movement of lipids and binding of lipids to organelles. Two transcript variants encoding the same protein have been found for this gene.[7]
