Protein binding microarrays highlight the diversification of DNA-binding motifs for the nuclear hormone receptor and C2H2 zinc finger transcription factor families, and reveal unexpected diversity in motifs for the T-box and DM families.
Seemingly redundant homologous transcription factors play distinct and cooperative roles in time-dependent combinatorial gene regulation and enable dynamic control of heterogeneity in the gene responses to environmental stresses.
Uncovering the mechanisms by which the transcription factor NRSF contributes to the development of epilepsy reveals that the regulation of gene expression by transcription factors in the brain is more finely-tuned than previously thought.
Experimental and computational analyses reveal how proteasomal hydrolysis is regulated and show that peptide transport is the rate-limiting step and the main differentiating factor between human standard- and immuno-proteasomes.
Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.
