| transcription factors | Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process. (12 Dec 1998) |
|---|---|
| transcription factors, tfii | The so-called general transcription factors that bind to RNA polymerase II and that are required to initiate transcription. They include tfiia, tfiib, tfiid, tfiie, tfiif, tfiih, tfii-I, and tfiij. In vivo they apparently bind in an ordered multi-step process and/or may form a large preinitiation complex called RNA polymerase II holoenzyme. (12 Dec 1998) |
| transcription factors, tfiii | Factors that bind to RNA polymerase III and aid in transcription. They include the assembly factors tfiiia and tfiiic and the initiation factor tfiiib. All combine to form a preinitiation complex at the promotor that directs the binding of RNA polymerase III. (12 Dec 1998) |
| dual leucine zipper bearing kinase | <enzyme> A serine/threonine kinase but hybrid between microtubule-associated protein kinase kinase kinases and the fibroblast growth factor receptor family; genbank u14636; do not confuse with the neoplasm protein dlk Registry number: EC 2.7.10.- Synonym: dlk kinase (26 Jun 1999) |
| zipper | <molecular biology> Motif found in certain DNA binding proteins. In a region of approximately 35 amino acids, every seventh is a leucine. This facilitates dimerisation of two such proteins to form a functional transcription factor. Examples of proteins containing leucine zippers are products of the proto-oncogenes myc, fos and jun. (15 Oct 1997) |
| zipper protein kinase | <enzyme> A putative serine/threonine protein kinase of 859 amino acids; has a leucine-zipper domain; has been sequenced; genbank u07358 Registry number: EC 2.7.10.- Synonym: zpk protein, leucine-zipper protein kinase (26 Jun 1999) |
| leucine zipper | <molecular biology> Motif found in certain DNA binding proteins. In a region of approximately 35 amino acids, every seventh is a leucine. This facilitates dimerisation of two such proteins to form a functional transcription factor. Examples of proteins containing leucine zippers are products of the proto-oncogenes myc, fos and jun.

| reverse transcription | <molecular biology> The process of copying information found in RNA into DNA. (09 Oct 1997) |
| transcription | <molecular biology> Synthesis of RNA by RNA polymerases using a DNA template. (18 Nov 1997) |
| transcription factor | <molecular biology> Protein required for recognition by RNA polymerases of specific stimulatory sequences in eukaryotic genes. Several are known that activate transcription by RNA polymerase II when bound to upstream promoters. Transcription of the 5S RNA gene in Xenopus by RNA polymerase III is dependent on a 40 kD protein TFIIIA that binds to a regulatory site in the centre of the gene and was the first protein found to exhibit the metal binding domains known as zinc fingers. (17 Mar 1998) |
| transcription factor ap-1 | A multiprotein complex composed of the products of c-jun and c-fos proto-oncogenes. These proteins must dimerise in order to bind to the ap-1 recognition site, also known as the tpa-responsive element (tre). Ap-1 controls both basal and inducible transcription of several genes. (12 Dec 1998) |
| transcription factor, sp1 | Promoter-specific RNA polymerase II transcription factor that binds to the gc box, one of the upstream promoter elements (upe) in mammalian cells. The binding of sp1 is necessary to initiate transcription in the promoters of a variety of cellular and viral genes including c-ha-ras and HIV. (12 Dec 1998) |
| transcription, genetic | The transfer of genetic information from DNA to messenger RNA by DNA-directed RNA polymerase. It includes reverse transcription and transcription of early and late genes expressed early in an organism's life cycle or during later development. (12 Dec 1998) |
| transcription unit | <molecular biology> A region of DNA that is transcribed to produce a single primary RNA transcript, i.e. A newly synthesised RNA molecule that has not been processed. Transcription units can be mapped by kinetic studies of RNA synthesis and in some instances directly visualised by electron microscopy. (17 Mar 1998) |
| erythroid transcription factor | <molecular biology> Transcription factor that binds to regulatory regions of genes expressed in erythroid cells. (18 Nov 1997) |
