The lipin protein family, consisting of three members, was first identified early this century. In the last few years, the lipin proteins have been shown to have important roles in glycerolipid biosynthesis and gene regulation, and mutations in the corresponding genes cause lipodystrophy, myoglobinuria, and inflammatory disorders. Here, we review some of the progress toward elucidating the molecular and physiological functions of the lipin proteins.
Supplementary key words lipodystrophy obesity triglyceride phosphatidate phosphatase insulin resistance Abbreviations: fld, fatty liver dystrophy; PAP, phosphatidate phosphatase; PPAR
