The large numbers of genes, their overlapping expression patterns and the over all complexity of the system hinted towards an elaborate mechanism for transcriptional control. Recent studies, however, offer evidence of a mole cular pathway governed by the interplay between two general transcription factors, CCAAT enhancer binding proteins (C/EBP) and GATA, an architectural protein, high mobility group A and a chromatin remod-eller, chromo-helicase/ATPase-DNA binding protein 1. In this review we present a parsimonious model that adequately describes regulation of transcription across all temporally regulated chorion genes, and propose a role for promoter architecture. © 2009 The Authors." }
