In the context of genetics, a transcription factor is a regulatory protein that initiates the transcription of certain genes upon binding with DNA. Genetics (from the Greek genno γεννώ= give birth) is the science of genes, heredity, and the variation of organisms. ... Protein involved in gene-expression regulation. ... Transcription may be one of the following: In linguistics, transcription is the conversion of spoken words into written language. ... This stylistic schematic diagram shows a gene in relation to the double helix structure of DNA and to a chromosome (right). ... Space-filling model of a section of DNA molecule Deoxyribonucleic acid (DNA)nucleic acid that contains the genetic instructions specifying the biological development of all cellular forms of life (and many viruses). ...
The binding of a transcription factor to a specific DNA sequence can result in either an increased rate of transcription of the gene, known as activated transcription, or repression of transcription, known as "silencing".
Any given gene will typically have its own pattern of binding sites for transcriptional activators and repressors ensuring that the gene is only transcribed in the proper cell type(s) and at the proper time during development.
See also transcription factor. In molecular biology, a transcription factor is a protein that binds DNA at a specific promoter or enhancer region or site, where it regulates transcription. ...
Transcriptionfactors can be selectively activated or deactivated by other proteins, often as the final step in signal transduction.
General transcriptionfactors are involved in the formation of a preinitiation complex.
The transcriptionfactors of this family are activated by the Janus Kinase JAK and dysregulation of this pathway is frequently observed in primary tumors and leads to increased angiogenesis and enhanced survival of tumors.
Transcriptionfactors can be activated or deactivated by other proteins.
Transcriptionfactors are primarily involved in the initiation stage of RNA transcription.
Examples of transcriptionfactors include Signal Transducers and Activator of Transcription (STAT), which regulate cell growth and are critical in cancer research and immunotherapy.
