The lipolysis-stimulated receptor (LSR) is a lipoprotein receptor primarily expressed in the liver and activated by free fatty acids [1]. It is thought to be involved in the clearance of triglyceride-rich lipoproteins, and has been shown in mice to be critical for liver and embryonic development [2].
