| suppressor tRNA | The tRNA associated with a suppressor mutation. (05 Mar 2000) |
|---|---|
| ochre suppressor | A gene that codes for an altered tRNA so that its anticodon can recognise the ochre codon and thus allows the continuation of protein synthesis. A suppressor of an ochre mutation is a tRNA that is charged with the amino acid corresponding to the original codon or a neutral substitute. Ochre suppressors will also suppress amber codons. (18 Nov 1997) |
| opal suppressor | <molecular biology> A gene that codes for an altered tRNA so that its anticodon can recognise the opal codon and thus allows the continuation of protein synthesis. A suppressor of an opal mutation is a tRNA that is charged with the amino acid corresponding to the original codon or a neutral substitute. Some eukaryote cells normally synthesise opal suppressor tRNAs. The function of these is not clear and they usually do not prevent normal termination of protein synthesis at an opal codon. (18 Nov 1997) |
| T-lymphocytes, suppressor-effector | Subpopulation of CD8+ T-lymphocytes which suppress antibody production or inhibit cellular immune responses. Suppressor-effector cells execute the message received from suppressor-inducer cells (T-lymphocytes, suppressor-inducer). (12 Dec 1998) |
| T-lymphocytes, suppressor-inducer | Subpopulation of CD4+ lymphocytes which induce CD8+ suppressor T-cells (T-lymphocytes, suppressor-effector) to suppress antibody production by B-cells. They also stimulate other cellular immune responses. (12 Dec 1998) |
| T suppressor cell | <haematology, immunology> Set of T lymphocytes (usually CD8) specifically involved in suppressing B-cell differentiation into antibody secreting cells. There may also be T suppresors of T-cell functions. (18 Nov 1997) |
| t-suppressor cell | A type of immune cells, also called t8 cells, these cells close down the immune response after it has destroyed invading organisms. T8 cells are sensitive to high concentrations of circulating lymphokine hormones and release their own lymphokines after an immune response has achieved its goal, signalling all other participants to cease their attack. Some memory B-cells remain to ward off a repeat attack by the invading organism. (12 Dec 1998) |
| tumour suppressor | <molecular biology, oncology> A gene that encodes a product that normally negatively regulates the cell cycle and that must be mutated or otherwise inactivated before a cell can proceed to rapid division. Examples: p53, RB retinoblastoma), WT 1 (Wilm's tumour), DCC (deleted in colonic carcinoma), NF 1 (neurofibrosarcoma) and APC adenomatous polyposis coli). (18 Nov 1997) |
| adenovirus e1a proteins | Proteins transcribed from the e1a region of adenovirus which are involved in positive regulation of transcription of the early genes. (12 Dec 1998) |
| adenovirus e1b proteins | Proteins transcribed from the e1b region of adenovirus which are involved in regulation of the levels of early and late gene expression. (12 Dec 1998) |
| adenovirus e1 proteins | The very first viral gene products synthesised after cells are infected with adenovirus. The e1 region of the genome has been divided into two major transcriptional units, e1a and e1b, each expressing proteins of the same name (adenovirus e1a proteins and adenovirus e1b proteins). (12 Dec 1998) |
| adenovirus e2 proteins | Proteins transcribed from the e2 region of adenovirus. Several of these are required for viral DNA replication. (12 Dec 1998) |
| adenovirus e3 proteins | Proteins transcribed from the e3 region of adenovirus but not essential for viral replication. The e3 19k protein mediates adenovirus persistence by reducing the expression of class I major histocompatibility complex antigens on the surface of infected cells. (12 Dec 1998) |
| adenovirus e4 proteins | Proteins transcribed from the e4 region of adenovirus. The e4 19k protein transactivates transcription of the adenovirus e2f protein and complexes with it. (12 Dec 1998) |
| adenovirus early proteins | <molecular biology, protein, virology> Proteins encoded by adenoviruses that are synthesised prior to, and in the absence of, viral DNA replication. The proteins are involved in both positive and negative regulation of expression in viral and cellular genes, and also affect the stability of viral mRNA. Some are also involved in oncogenic transformation. (12 Dec 1998) |
