ProteomicsACONITASE 3 is part of the ANAC017 transcription factor-dependent mitochondrial dysfunction response
Mitochondria are tightly embedded within metabolic and regulatory networks that optimize plant performance in response to environmental challenges. The best-known mitochondrial retrograde signaling pathway involves stress-induced activation of the transcription factor NAC DOMAIN CONTAINING PROTEIN 1...

ProteomicsNucleosome binding by the pioneer transcription factor OCT4
The nucleosome is a fundamental unit of chromatin in eukaryotes, and generally prevents the binding of transcription factors to genomic DNA. Pioneer transcription factors overcome the nucleosome barrier, and bind their target DNA sequences in chromatin. OCT4 is a representative pioneer transcription...

ProteomicsTime-course proteomics analysis of human regulatory T cell (Treg) differentiation
Human naïve CD4+ T cells (CD4+ CD45RA+ CD25- CD45RO- CD8- CD14- CD15- CD16- CD19- CD34- CD36- CD56- CD123- TCRγ/δ- HLA-DR- and CD235a-) were magnetically negatively isolated from peripheral blood. Cells were stimulated with anti-CD3/anti-CD28 antibodies plus IL-2, and samples were taken at 6h, 24h, ...

ProteomicsHIC1 interacts with FOXP3 multi protein complex: a novel mechanism to regulate human regulatory T cell differentiation and function
Transcriptional repressor, hypermethylated in cancer 1 (HIC1) is an important contributor to regulatory T (Treg) cell development and function. To investigate the mechanism by which it regulates Treg cell development, we systematically characterized the HIC1 interactome by affinity-purification mass...

ProteomicsAnalysis of E2F2 interacting proteins
In an attempt to identify proteins interacting with transcription factor E2F2, proteins extracted from HA-E2F2 overexpressing HEK293T cells were were subjected to immunoprecipitation (IP) with an anti-HA antibody or, as a negative control (NegCt), with an anti-T antibody. Immunoprecipitated proteins...

TranscriptomicsNOT2 proteins promote Pol II-dependent transcription and interact with multiple miRNA biogenesis factors in Arabidopsis
MicroRNAs (miRNAs) play key regulatory roles in numerous developmental and physiological processes in animals and plants. The elaborate mechanism of miRNA biogenesis involves transcription and multiple processing steps. Here, we report the identification of a pair of evolutionarily conserved NOT2_3_...

TranscriptomicsMuscleblind-like proteins regulate embryonic stem cell-specific alternative splicing and reprogramming II
Previous investigations of the core gene regulatory circuitry that controls embryonic stem cell (ESC) pluripotency have largely focused on the roles of transcription, chromatin and non- coding RNA regulators. Alternative splicing (AS) represents a widely acting mode of gene regulation, yet its role ...

ProteomicsHomeostatic and Interferon-induced gene expression represent different states of promoter-associated transcription factor ISGF3
Host defense by the innate immune system requires the establishment of antimicrobial states allowing cells to cope with microorganisms before the onset of the adaptive immune response. Interferons (IFN) are of vital importance in the establishment of cell-autonomous antimicrobial immunity. Speed is...

TranscriptomicsTranscription factor trapping by RNA in gene regulatory elements (CLIP-Seq)
Transcription factors (TFs) bind specific sequences in promoter-proximal and distal DNA elements in order to regulate gene transcription. RNA is transcribed from both promoter-proximal and distal DNA elements, and some DNA-binding TFs have also been shown to bind RNA. These obsevations led us to p...
