WebMar 3, 2024 · We recently discovered yeast “Forkhead Box” (Fox) DNA binding proteins, Forkhead 1 (Fkh1) and Forkhead 2 (Fkh2), as required for this origin clustering and regulation of initiation timing. This study reveals that Fkh1 and Fkh2 share a structural motif that allows dimerization to bring distal DNA binding sites into close proximity. WebYeast cells rely on the SPS-sensing pathway to respond to extracellular amino acids. This nutrient-induced signal transduction pathway regulates gene expression by controlling the activity of two redundant transcription factors: Stp1 and Stp2. These factors are synthesized as latent cytoplasmic proteins with N-terminal regulatory domains.
