Predicted to enable lipid binding activity. Acts upstream of or within bile acid secretion and positive regulation of peroxisome proliferator activated receptor signaling pathway. Located in several cellular components, including cytosol; intercellular canaliculus; and microvillus. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and liver and biliary system. Orthologous to human STARD10 (StAR related lipid transfer domain containing 10). [provided by Alliance of Genome Resources, Apr 2022]
