Lipid droplets lead a Spartin existence.

The article discusses research on an unexpected role for Spartin, a protein linked to the neuronal disease Troyer syndrome, in regulating lipid droplets (LDs). It references a study by S. W. Eastman et al in this same issue. It states that cells carry excess fats into LDs, where they are stored until needed as sources of energy. According to the researcher, Spartin localizes to LDs and binds to a known LD protein called TIP47.
