Gcn4 is a yeast transcriptional activator induced by amino acid starvation. ChIP-seq analysis revealed 546 genomic sites occupied by Gcn4 in starved cells, representing ~30% of all Gcn4 binding-motifs. Deviation from the consensus motif and nucleosome occupancy are key negative determinants of Gcn4 binding. Surprisingly, only ~40% of the bound sites are in promoter regions, and only ~50-67% of these activate transcription, indicating extensive negative control over Gcn4 function. Most of the re...

How this grade was computed

The insufficient grade is a transparent weighted average. Each metric below scored from 0–100% against the published ChIP-seq thresholds, weighted by its importance; nothing is hidden or subjective.
