| paired box domain | <molecular biology> Conserved domain of 128 amino acids, found in several developmentally regulated proteins in Drosophila (for example paired, gooseberry, Pox), mouse and human (for example Pax, HuP1, HuP48). (18 Nov 1997) |

| 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) |
| paired | Developmentally regulated gene in Drosophila that contains the paired box domain. (18 Nov 1997) |
| paired allosome | Paired allosomes; the pair of centrioles of mammalian cells. Synonym: paired allosome. Origin: diplo-+ G. Soma, body (05 Mar 2000) |
| paired-associate learning | Learning in which the subject must respond with one word or syllable when presented with another word or syllable. (12 Dec 1998) |
| paired associates | Words, syllables, digits, or other items learned in pairs, so that when one is given, its associate is to be recalled. (05 Mar 2000) |
| paired beats | See: bigeminy. (05 Mar 2000) |
| paired organelles | Electron-dense club-shaped, tubular or saccular organelles extending back from the anterior end of sporozoites and other stages of certain sporozoans in the subphylum Apicomplexa. Synonym: paired organelles, toxoneme. Origin: G. Rhopalon, club (05 Mar 2000) |
| 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) |
