A regulatory locus for mouse beta-glucuronidase induction, Gur, controls messenger RNA activity
Science (New York, N.Y.)
|February 9, 1979
Summary
The Gur locus in mice controls kidney beta-glucuronidase messenger RNA activity. This regulation occurs after testosterone induces the Gus gene, impacting enzyme production.
Area of Science:
- Molecular biology
- Genetics
- Biochemistry
Background:
- Gene regulation is crucial for cellular function.
- Messenger RNA (mRNA) activity is a key step in protein synthesis.
- Hormonal induction of gene expression is a fundamental biological process.
Purpose of the Study:
- To investigate the role of the Gur locus in regulating kidney beta-glucuronidase mRNA.
- To understand how testosterone induction affects beta-glucuronidase gene expression.
- To characterize the control mechanisms of specific mRNA activity in higher organisms.
Main Methods:
- Utilizing Xenopus oocytes as an in vitro system for mRNA translation.
- Assaying beta-glucuronidase mRNA activity by measuring synthesized enzyme.
- Employing testosterone to induce the Gus structural gene in mice.
Main Results:
- The Gur locus was identified as a key regulator of kidney beta-glucuronidase mRNA activity.
- Testosterone induction of the Gus gene leads to specific changes in mRNA levels.
- Functional assays in oocytes confirmed the regulatory role of the Gur locus.
Conclusions:
- The Gur locus exerts control over beta-glucuronidase mRNA production in response to testosterone.
- This study elucidates a specific regulatory mechanism for mRNA activity in mammals.
- Findings contribute to understanding gene expression control in higher organisms.

02:24Regulation of Expression Occurs at Multiple Steps
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

02:23Master Transcription Regulators
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...
02:22Regulated mRNA Transport
In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing specific...
02:11Reporter Genes
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
