DNA binding controls inactivation and nuclear accumulation of the transcription factor Stat1 [PDF]
Cytokine-dependent gene transcription greatly depends on the tyrosine phosphorylation (“activation”) of Stat proteins at the cell membrane. This rapidly leads to their accumulation in the nucleus by an unknown mechanism. We performed microinjections of recombinant Stat1 protein to show that nuclear accumulation of phosphorylated Stat1 can occur without

Gene Activation by the Cytokine-Driven Transcription Factor STAT1
Signal transducers and activators of transcription (STATs) are a family of cytokine-regulated transcription factors, which serve the dual role of external signal transduction and transcriptional activation. The founding member of this family, STAT1, is involved in a plethora of cellular processes, including interferon-dependent upregulation of various ...

CDK8 Kinase Phosphorylates Transcription Factor STAT1 to Selectively Regulate the Interferon Response [PDF]
Gene regulation by cytokine-activated transcription factors of the signal transducer and activator of transcription (STAT) family requires serine phosphorylation within the transactivation domain (TAD). STAT1 and STAT3 TAD phosphorylation occurs upon promoter binding by an unknown kinase.

Cellular responses mediated by the transcription factor STAT1 in murine inflammatory diseases [PDF]
The intracellular transduction of interferon signals from the plasma membrane to the nucleus is mediated by signal transducer and activator of transcription 1 (STAT1) which acts in tetrameric form as a transcription factor in immune responses. In this project, the protomer exchange between STAT1 dimers was studied under kinetic aspects and this process

Stat1 phosphorylation determines Ras oncogenicity by regulating p27 kip1. [PDF]
Inactivation of p27 Kip1 is implicated in tumorigenesis and has both prognostic and treatment-predictive values for many types of human cancer. The transcription factor Stat1 is essential for innate immunity and tumor immunosurveillance through its ...

Activated STAT1 Transcription Factors Conduct Distinct Saltatory Movements in the Cell Nucleus [PDF]
The activation of STAT transcription factors is a critical determinant of their subcellular distribution and their ability to regulate gene expression. Yet, it is not known how activation affects the behavior of individual STAT molecules in the cytoplasm and nucleus.

Signal transducer and activator of transcription-1 localizes to the mitochondria and modulates mitophagy [PDF]
The signal transducer and activator of transcription (STAT) proteins are latent transcription factors that have been shown to be involved in cell proliferation, development, apoptosis, and autophagy. STAT proteins undergo activation by phosphorylation at
