hemechanisms that co-ordinately activate lipid synthesiswhen high rates ofmembrane biogenesis are needed to support cell growth are largely unknown. c-Fos, a well known AP-1 transcription factor, has emerged as a unique protein with the capacity to associate to specific enzymes of the pathway of synthesis of phospholipids at the endoplasmic reticulum and activate their synthesis to accompany genomic decisions of growth. Herein,we discuss this cytoplasmic, non-genomic effect of c-Fos in the context of other mechanisms that have been proposed to regulate lipid synthesis.
