TranscriptomicsGene target specificity of the Super Elongation Complex (SEC) family: How HIV-1 Tat employs selected SEC members to activate viral transcription
The AF4/FMR2 proteins AFF1 and AFF4 act as a scaffold to assemble the Super Elongation Complex (SEC) that strongly activates transcriptional elongation of HIV-1 and cellular genes. Although they can dimerize, it is unclear whether the dimers exist and function within a SEC in vivo. Furthermore, it i...

ProteomicsA chaperone-like function of FUS ensures TAZ condensates dynamics and transcriptional activation
The Hippo pathway plays important roles in organ development, tissue homeostasis, and tumor growth, and its downstream effector TAZ is a transcriptional coactivator that promotes target gene expression through the formation of biomolecular condensates. However, the mechanisms that regulate the biop...

ProteomicsHSPA1A and DNAJB1 regulate NELF condensate reversibility to safeguard transcriptional recovery under heat stress
The negative elongation factor (NELF) is essential in establishing RNA Polymerase II (Pol II) pausing at promoter-proximal regions, providing a key regulatory checkpoint for precise gene expression control. In response to heat shock (HS) stress, NELF has been observed to form nuclear condensates, bu...
