Is STAT1 a transcription factor?
Stat1 is a functional transcription factor even in the absence of inducer-mediated activation, participating in the constitutive expression of some genes.
What is the function of STAT1?
Normal Function The STAT1 gene provides instructions for making a protein that is involved in multiple immune system functions, including the body’s defense against a fungus called Candida. When the immune system recognizes Candida, it generates cells called Th17 cells.
What activates STAT1?
STAT1 is activated by IFNs and other cell signals. Following activation, STAT1 is translocated to the nuclei and activates transcription of IFN-stimulated genes.
What is a ubiquitous transcription factor?
Abstract. The ubiquitous transcription factor Yin Yang 1 (YY1) is known to have a fundamental role in normal biologic processes such as embryogenesis, differentiation, replication, and cellular proliferation.
What is Isre interferon?
Interferon-sensitive response element (ISRE) is mainly responsible for IFN-alpha-induced upregulation of programmed death-1 (PD-1) in macrophages. Biochim Biophys Acta.
Where is STAT1 located?

Are activators and repressors transcription factors?
According to the conventional wisdom, transcription factors are typically classified as “activators” or “repressors”. Activators recruit coactivators, resulting in gene activation, while repressors recruit corepressors, leading to transcriptional repression.
Is NF-κB a transcription factor?
Nuclear factor-kappa B (NF-κB) is a ubiquitous transcription factor that is involved in inflammatory and immune responses, as well as in regulation of expression of many other genes related to cell survival, proliferation, and differentiation.
