|---|---|
| HGM | hog gastric mucosa; human gene mapping; human glucose monitoring |
| HPR | haptoglobin-related gene; health practices research |
| hsp | heat shock protein [gene] |
| hut | histidine utilization [gene] |
| gene products, rex | Post-transcriptional regulatory proteins required for the accumulation of mRNAs that encode the gag and env gene products in HTLV-I and HTLV-II. The rex (regulator x; x is undefined) products act by binding to elements in the ltr. (12 Dec 1998) |
|---|---|
| gene products, tat | Trans-acting transcription factors. Nuclear proteins whose expression is required for HIV viral replication. The tat protein stimulates HIV-ltr-driven RNA synthesis for both viral regulatory and viral structural proteins. Tat stands for trans-activation of transcription. (12 Dec 1998) |
| gene products, tax | Transcriptional trans-acting proteins of the promoter elements found in the long-terminal repeats (ltr) of HTLV-I and HTLV-II. The tax (trans-activator x; x is undefined) proteins act by binding to enhancer elements in the ltr. (12 Dec 1998) |
| gene products, vif | A 23 kD regulatory protein important for virion infectivity in HIV. The protein is found in the cytoplasm of HIV-infected cells and is not absolutely required for virion formation. (12 Dec 1998) |
| gene products, vpr | Trans-acting proteins which accelerate virus replication in HIV. The vpr proteins act in trans to increase the levels of HIV specified proteins. Vpr is short for viral protein r, where r is undefined. (12 Dec 1998) |
| gene products, vpu | Non-glycosylated, membrane-associated, 16 kD proteins which are expressed in large amounts in cells infected with HIV-1. The proteins are required for efficient virion maturation and release. They are not present in HIV-2 nor in siv. Vpu is short for viral protein u, with u undefined. (12 Dec 1998) |
| gene redundancy | A situation in which many copies of the same gene exist in a genome. (09 Oct 1997) |
| gene regulation | The DNA and protein interactions in a gene that determine the temporal and spatial modes of expression as well as the amplitude of expression. (14 Nov 1997) |
| gene regulatory protein | <molecular biology> Any protein that interacts with DNA sequences of a gene and controls its transcription. (18 Nov 1997) |
| gene sequencing | Determination of the sequence of nucleotide bases in a strand of DNA. (14 Nov 1997) |
| gene splicing | A procedure by which one DNA molecule or fragment can be attached to another. (14 Nov 1997) |
| gene supression | <molecular biology> The halting of abnormal gene activity which results in the restoration of lost or impaired genetic function. (09 Oct 1997) |
| mapping, gene | Charting the positions of genes on chromosome and learning the distance, in linkage units or physical units, between genes. (12 Dec 1998) |
| gene switch | <molecular biology> A situation in which a cell or organism stops expressing one gene orgene group and switches to expressing a different gene or group of genes. (09 Oct 1997) |
| gene synthesis | <molecular biology> The complete synthesis of a gene using a DNA synthesiser (gene machine), or the assembly of oligonucleotides so synthesised into a synthetic gene, as opposed to cloning. (14 Nov 1997) |
