The conserved biochemical activity of the duplicate Bab transcription factors were integrated into the regulatory hierarchy of an evolving gene regulatory network by binding site gains in a target gene's cis-regulatory region.
A gene duplication event has permitted the functional specialization of a homeodomain transcription factor through changes in exon-intron organization and these changes have supported the evolution of a major, phylum-level morphological novelty.
Thalidomide and its derivates induce degradation of many C2H2 zinc-finger transcription factors, including SALL4, providing insight into a long-standing mystery in modern pharmacology, and starting points for future drug development.
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.
Eukaryotic translation elongation factor 1A1 controls the process of heat shock response, from transcriptional activation of the HSP70 gene, to HSP70 mRNA stabilization, nuclear export, and translation.
Drosophila has almost all transcription factor binding specificities available to humans; and human transcription factors with divergent specificities operate in cell types that are not found in fruit flies.
