| DABP | D site albumin promoter binding protein |
|---|---|
| E* | lesion on the erythrocyte cell membrane at the site of complement fixation |
| FMR | fragile site mental retardation [syndrome]; Friend-Moloney-Rauscher [antigen] |
| fra | fragil [site] |
| FRAXE | X-linked mental retardation-fragile site [syndrome] |
| integrated rate expression | An equation of a chemical or enzyme-catalyzed reaction for the entire progress curve. (05 Mar 2000) |
|---|---|
| oocyte expression | <molecular biology> Technique whereby the cellular machinery of an oocyte (typically that of Xenopus) is utilised to transcribe functional protein from microinjected RNA. (18 Nov 1997) |
| expression | <molecular biology> The process by which a gene's coded information is converted into the structures present and operating in the cell. Expressed genes include those that are transcribed into mRNA and then translated into protein and those that are transcribed into RNA but not translated into protein (for example, transfer and ribosomal RNAs). (06 Aug 1998) |
| expression cloning | <molecular biology> A vector that results in the expression of inserted DNA sequences when propagated in a suitable host cell, i.e. The protein coded for by the DNA is synthesised by the host's system. (06 Aug 1998) |
| expression, gene | A gene speaks. When a gene is expressed, the information encoded in the gene is translated into protein or RNA structures present and operating in the cell. Expressed genes include genes that are transcribed into messenger RNA (mRNA) and then translated into protein as well as those genes that are transcribed into RNA (such transfer and ribosomal RNAs) but not translated into protein. (12 Dec 1998) |
| expression library | <molecular biology> A library of DNA fragments which was created with an expression vector so that any genes present in the library are expressed. (09 Oct 1997) |
| expression-linked copy | <molecular biology> One of many different versions of the variable surface glycoprotein gene of the trypanosome (a parasitic protozoan which causes the disease African sleeping sickness), refers to whichever one of them is currently being expressed on the outer surface of the trypanosome. (09 Oct 1997) |
| expression system | <molecular biology> Combination of an expression vector, its cloned DNA, and the host for the vector that provide a context to allow foreign gene function in a host cell, that is, produce proteins at a high level. (13 Nov 1997) |
| expression vector | <molecular biology> A cloning vector that contains the necessary regulatory sequences to allow transcription and translation of a cloned gene or genes and thus transcribe and clone DNA. (13 Nov 1997) |
| facial expression | Observable changes of expression in the face in response to emotional stimuli. (12 Dec 1998) |
| acceptor site | The ribosomal binding site for the aminoacyl-tRNA during protein synthesis. (05 Mar 2000) |
| acceptor splicing site | Boundary between the right end of an intron and the left end of the adjacent exon. Synonym: acceptor splicing site. (05 Mar 2000) |
| active site | <chemistry> A specific region of an enzyme where a substrate binds and catalysis takes place (binding site). (06 May 1997) |
| allosteric site | A specific site on a multi-subunit enzyme or other protein that is not the substrate binding site, but that when reversibly bound by an effector, induces a conformational change in the protein, altering its catalytic or binding properties. (12 Dec 1998) |
| amidation site | <molecular biology> A C terminus consensus sequence, required for C terminus amidation of peptides. Consensus is glycine, followed by 2 basic amino acids (arg or lys). (18 Nov 1997) |
