What type of transcription factor is Sp1?
What type of transcription factor is Sp1?
zinc finger family transcription factor
Specificity protein 1 (Sp1) is a zinc finger family transcription factor. Sp1 can regulate a number of genes that influence cell survival and proliferation.
Is Sp1 a general transcription factor?
Initially, Sp1 was considered a general transcription factor that is required for transcription of a large number of ‘housekeeping genes’, so-called because of their involvement in metabolism, cell proliferation/growth, and cell death [3].
What is SP1 gene?
SP1 belongs to the Sp/KLF family of transcription factors. The protein is 785 amino acids long, with a molecular weight of 81 kDa. The SP1 transcription factor contains two glutamine-rich activation domains at its N-terminus that are believed to be necessary for promoter trans-activation.
What does SP1 stand for?
SP1
| Acronym | Definition |

| SP1 | Service Pack 1 (Microsoft) |
| SP1 | Serine Protease 1 (enzyme) |
| SP1 | Specific Protein 1 (biochemistry) |
| SP1 | Stimulatory Protein 1 (biochemistry) |
What is AP-1 transcribe?
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.
What activates AP-1?
AP-1 activity is stimulated by external stimuli like growth factors or inflammatory cytokines and a complex network of kinase such as mitogen-activated protein kinases (MAPKs) of the extracellular-signal regulated kinase (ERK), p38, and JUN amino-terminal kinase (JNK) families.
How do you identify transcription factors?
DNA BINDING ASSAYS USED TO STUDY TRANSCRIPTION FACTORS. The principal strategy in identifying and characterizing transcription factors is based on their ability to recognize and interact with specific DNA sequences present in the promoters of eukaryotic genes.
What is the role of Sp1?
Sp1 is a ubiquitous nuclear factor that plays a key role in maintaining basal transcription of ‘house-keeping’ genes. However, recent evidence points to a more important function for Sp1 in mediating ‘cross-talk’ between selected signaling cascades to regulate the target genes that respond to these pathways.
What is the function of Sp1?
Subsequently, Sp1 has been recognized to function as a transcription factor, required for transcription at many TATA promoters as well as regulating TATA-less promoters via protein–protein interactions or interplay with other transcription factors and components of the basal transcriptional machinery (3).
What is SP1 biology?
What is SP1 in law?
SP1 means the publication titled Standards and Practices for Control Surveys (SP1) as amended from time to time, published by the Inter-Governmental Committee on Surveying and Mapping.
What activates ap1?
What does ap1 induce?
AP-1 activity is induced by numerous extracellular matrix and genotoxic agents, suggesting involvement in programmed cell death. Many of these stimuli activate the c-Jun N-terminal kinases (JNKs) leading to the phosphorylation of Jun proteins and enhanced transcriptional activity of AP-1 dependent genes.
What does the AP-1 gene do?
What is AP-1 complex?
Activator protein 1 (AP-1) is a ubiquitous collection of protein complexes known to regulate transcription in response to environmental stimuli.
How do you find transcription factors?
Go to Eukaryotic Promoter database, put in the NCBI accession number for your gene of interest and then search for the transcription factors of your interest for that promoter sequence. Promoter sequence can also be limited (eg. -500 to +100) or extended (-1000 to +1) the way you like.
