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 does transcription factors bind to?

DNA promoter sequence
Some transcription factors bind to a DNA promoter sequence near the transcription start site and help form the transcription initiation complex. Other transcription factors bind to regulatory sequences, such as enhancer sequences, and can either stimulate or repress transcription of the related gene.

What controls STAT1 expression?

Study reports that MAGEA3 interacts with STAT1 and regulates the expression of tyrosine phosphorylated STAT1 (pY-STAT1) in tumor cells. MAGEA3 expression in tumor cells is associated with immune cells infiltration into tumor microenvironment and anti-tumor immune responses.

Is transcription factor A binding site?

Transcription Factor Binding Sites (TFBSs) Transcription factors (TFs) are proteins with DNA binding activity that are involved in the regulation of transcription. Generally, TFs modulate gene expression by binding to gene promoter regions or to distal regions called enhancers.

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 transcription factors bind directly to DNA?

In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence.

Where do most transcription regulators bind?

How or where do most transcription regulators bind? Most transcriptional regulator proteins bind DNA as dimers. Dimerization roughly doubles the area of contact with the DNA, making the interaction tighter and more specific.

Do all transcription factors bind DNA?

Due to the nature of these chemical interactions, most transcription factors bind DNA in a sequence specific manner. However, not all bases in the transcription factor-binding site may actually interact with the transcription factor.

Do transcription factors bind to promoter or enhancer?

It is doubtful that lineage-specific DNA binding transcription factors are solely responsible for establishing enhancer–promoter interactions. Enhancer bound transcription factors recruit co-activators and general factors of which some have been shown to play a vital role in enhancer–promoter communication.
