Chromosomal localization of the human elastin gene
American Journal of Human Genetics
|September 1, 1985
Summary
Researchers identified a human elastin gene clone (pcHEL1) using fetal aorta mRNA. In situ hybridization localized the elastin gene to chromosome 2, specifically the q31----qter region.
Area of Science:
- Molecular Biology
- Human Genetics
- Biochemistry
Background:
- Elastin is a crucial protein for tissue elasticity.
- Understanding elastin gene localization is important for genetic studies.
Purpose of the Study:
- To isolate and characterize a human elastin gene clone.
- To determine the chromosomal location of the human elastin gene.
Main Methods:
- Synthesized cDNA from fetal human aorta mRNA.
- Cloned cDNA into pBR322 and screened with sheep elastin cDNA.
- Sequenced the human clone (pcHEL1) and performed in situ hybridization.
Main Results:
- Successfully isolated and sequenced a human elastin clone (pcHEL1).
- The DNA sequence showed homology to sheep elastin cDNA.
- In situ hybridization mapped the elastin gene to chromosome 2 (q31----qter).
Conclusions:
- The human elastin gene is located on chromosome 2.
- This finding provides a basis for further genetic and molecular studies of elastin.
