Structure of a chromosomal gene for human interferon beta
1Department of Biochemistry, Cancer Institute, Japanese Foundation for Cancer Research, Toshima-ku, Tokyo 170, Japan.
Summary
Researchers cloned and analyzed the human interferon beta(1) gene, finding its sequence matches previous cDNA data. Homology upstream suggests a role in gene expression, and the gene lacks intervening sequences, similar to interferon alpha(1).
Area of Science:
- Molecular Biology
- Genetics
- Immunology
Background:
- The human interferon beta(1) gene is crucial for immune responses.
- Previous studies reported cDNA sequences, but chromosomal gene structure was less understood.
Purpose of the Study:
- To clone and analyze the chromosomal DNA segment of the human interferon beta(1) gene.
- To compare its sequence with known cDNA and identify regulatory elements.
Main Methods:
- Cloning a human interferon beta(1) gene from a human gene library.
- Nucleotide sequencing of the chromosomal DNA.
- Nuclease S1 mapping experiments.
Main Results:
- The chromosomal interferon beta(1) gene sequence is identical to the previously reported cDNA sequence.
- Significant nucleotide sequence homology was found upstream of the transcription initiation site between interferon beta(1) and alpha(1) genes.
- The interferon beta(1) gene, like interferon alpha(1), lacks intervening sequences (introns).
Conclusions:
- The upstream homologous region may be involved in regulating interferon gene expression.
- The structural similarity, including the absence of introns, highlights conserved features in interferon gene organization.

01:30Structure of a Gene
A gene is the fundamental unit of heredity. Every individual has two copies of each gene, one inherited from each parent. Although most people contain the same genes, there is a small fraction that is slightly different amongst people. A gene with a small difference in its sequence of DNA bases forms different alleles, contributing to different phenotypes.
However, only 1% of the DNA is composed of genes that encode proteins; the rest, 99% is non-coding DNA. This non-coding DNA performs...

Overview
01:30General Transcription Factors
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
02:35Chromatin Position Affects Gene Expression
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

02:32Exon Recombination
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon has three reading...

02:02Cis-regulatory Sequences
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...
