What is the role of transcription factor Sp1?
What is the role of transcription factor Sp1?
Sp1 was the first characterized and still is one of the best studied mammalian transcription factors. It functions as a transcriptional activator of a variety of genes including house-keeping genes, cell cycle regulators and tissue-restricted genes.
What are the 4 transcription factors?
The transcription factors Oct4, Sox2, Klf4 and Nanog act as triggers for the induction of somatic cells to pluripotent stem cells. Oct4, Sox2, Klf4 and Nanog are all essential in stem cells and play an important role in biological processes.
Is AP 1 a transcription factor?
AP-1 is a dimeric transcription factor composed of proteins belonging to the Jun (c-Jun, JunB, and JunD), Fos (c-Fos, FosB, Fra1, and Fra2), and activating transcription factor protein families.
Which is a transcription factor?
Transcription factors are proteins involved in the process of converting, or transcribing, DNA into RNA. Transcription factors include a wide number of proteins, excluding RNA polymerase, that initiate and regulate the transcription of genes. Regulation of transcription is the most common form of gene control.
What type of transcription factor is Sp1?
Specificity protein 1 and survivin Specificity protein 1 (Sp1) is a zinc finger family transcription factor. Sp1 can regulate a number of genes that influence cell survival and proliferation. Notably, Sp1 overexpression is observed in several cancers, including PaCa.
What is Sp1 gene?
SP1 (Sp1 Transcription Factor) is a Protein Coding gene. Diseases associated with SP1 include Embryonal Carcinoma and Cerebrotendinous Xanthomatosis. Gene Ontology (GO) annotations related to this gene include DNA-binding transcription factor activity and sequence-specific DNA binding.
What are examples of transcription factors?
Mechanistic
| Examples of specific transcription factors | ||
|---|---|---|
| Factor | Structural type | Recognition sequence |
| Heat shock factor | Basic zipper | 5′-XGAAX-3′ |
| ATF/CREB | Basic zipper | 5′-TGACGTCA-3′ |
| c-Myc | Basic helix-loop-helix | 5′-CACGTG-3′ |
What is the function of AP 1?
Activator protein 1 (AP-1) is a transcription factor that regulates gene expression in response to a variety of stimuli, including cytokines, growth factors, stress, and bacterial and viral infections. AP-1 controls a number of cellular processes including differentiation, proliferation, and apoptosis.
Is SP1 a transcription factor?
Sp1 (specificity protein 1) is a well-known member of a family of transcription factors that also includes Sp2, Sp3 and Sp4, which are implicated in an ample variety of essential biological processes and have been proven important in cell growth, differentiation, apoptosis and carcinogenesis.
