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.
Gene product: The biochemical material, either RNA or protein, resulting from expression of a gene. The amount of gene product is used to measure how active a gene is; abnormal amounts can be correlated with diseasecausing alleles.
All these gene products are used within the mitochondrion, but the mitochondrion also needs proteins encoded by nuclear genes.
The proto-oncogene product c-Myc can induce cell growth and proliferation.
A gene product (usually protein) that positively regulates transcription. Activators may either increase binding of RNA polymerase to the promoter (closed complex formation) or stimulate RNA polymerase to begin transcription (open complex formation).
The scarecrow-like gene products or transcription factors are involved in very early cellular differentiation and development.
DNA probe -- any biochemical used to identify or isolate a gene, a gene product, or a protein.
coli cell, the J protein in the tail tip interacting with the lamB gene product of E. coli, a porin molecule which is part of the maltose operon. The linear phage genome is injected past the cell outer membrane.
Significantly, floor plate and motor neurons, cell types that are absent in Shh mutants (Chiang et al. 1996), differentiate in embryos mutant for both opb and Shh, suggesting that the opb gene product acts downstream of Shh as a negative regulator ...
It is an autosomal recessive disease in which the parents are unaffected carriers of a mutant gene that does not produce its gene product, one of the lysosomal enzymes. This gene normally codes for an enzyme that degrades a lipid found in the brain.
Three-dimensional structure of gene product (protein) with known or implied function. eg DNA binding membrane spanning. A motif is often inferred from a cDNA sequence. Related Terms: Protein ...

Two additional classes of segmentation genes are expressed after the gap gene products. The pair-rule genes are expressed in striped patterns of seven bands perpendicular to the anterior-posterior axis (see the example, even-skipped).
Now the term allele is used for two or more alternative forms of a gene resulting in different gene products and thus different phenotypes. In a haploid set of chromosomes there is only one allele at its specific locus.
FUSION PROTEIN - A product of recombinant DNA in which the foreign gene product is juxtaposed ("fused") to either the carboxyl-terminal or amino-terminal portion of a polypeptide encoded by the vector itself.
And that imprinting, the reason it's important is that chemical modification, which is passed on from the mother or the father to the offspring, changes the function of the gene or the gene product, ...
inability to synthesize the lac Z+ gene product, ß-galactosidase. D. lac Z+ gene is inducible, but unable to be repressed by high glucose.
exon Part of the mRNA as transcribed from the DNA that contains a portion of the information necessary for final gene product. exopod, exopodite. Lateral branch of a biramous crustacean appendage.
Null mutation A mutation which leads to the absence of a gene product.
Many scientists believe that nuclear lamins are the evolutionary ancestor of cytoplasmic intermediate filaments, which evolved through duplication and translocation of the gene product to the cytoplasm.
about 1000 chromatids; produced by DNA replication without mitosis. When viewed under a microscope, the many chromatids look like a giant chromosome. The large number of chromatids allows the cell to produce more mRNA and therefore more gene product ...
These are types of mutations. Since DNA is information, and information typically has a beginning point, an inversion would produce an inactive or altered protein. Likewise deletion or duplication will alter the gene product.
Plunkett G et al (1999) Sequence of shiga toxin 2 phage 933W from Escherichia coli O157:H7: shiga toxin as a late-gene product. J. Bacteriol 181, 1767 8.
that is adjacent to a group of structural genes and is the target sequence for a repressor protein; a unit of gene regulation and expression that includes structural genes and regulatory elements recognized by one or more regulatory gene products.
