Abstract
A new layer of gene regulation emerges for the metabolic regulator peroxisome proliferator–activated receptor-
(PPAR-). A team consisting of a Krüppel-like transcription factor and a SUMO protease regulate the expression of PPAR- target genes, thereby controlling energy metabolism (pages 656–666).
Cells need to finely tune gene expression to maintain homeostasis. Such control is achieved partly through the actions of sequence-specific transcription factors and associated coregulators1.
