Summary
Researchers cloned the human growth arrest-specific gene GAS3 cDNA, which encodes peripheral myelin protein 22 (PMP22). This protein is linked to Charcot-Marie-Tooth disease type 1A, a form of inherited peripheral neuropathy.
Area of Science:
- Molecular Biology
- Neuroscience
- Genetics
Background:
- The growth arrest-specific gene GAS3 encodes a transmembrane glycoprotein.
- Peripheral myelin protein 22 (PMP22) is a key component of myelin in the peripheral nervous system.
Purpose of the Study:
- To clone the human GAS3 cDNA.
- To identify the protein encoded by GAS3.
- To investigate the role of GAS3/PMP22 in peripheral neuropathies.
Main Methods:
- Gene cloning techniques were employed to isolate the human GAS3 cDNA.
- The encoded protein was characterized as a transmembrane glycoprotein.
Main Results:
- The human GAS3 cDNA was successfully cloned.
- The cloned cDNA encodes peripheral myelin protein 22 (PMP22).
- PMP22 was identified as the protein product of GAS3.
Conclusions:
- The GAS3 gene encodes PMP22, a transmembrane glycoprotein.
- PMP22 is implicated in the pathogenesis of Charcot-Marie-Tooth disease type 1A.
- This finding provides a molecular basis for understanding this inherited peripheral neuropathy.

02:51Multi-species Conserved Sequences
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...

02:35RACE - Rapid Amplification of cDNA Ends
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.

03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

01:05Maxam-Gilbert Sequencing
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
