Primary structure of two nonallelic beta-globin chains from DBA/2 mice
Biochemical Genetics
|June 1, 1987
Summary
The amino acid sequences of beta globin chains in DBA/2 mice were determined. These sequences match those predicted from BALB/c mouse globin genes, indicating limited evolutionary divergence in these mouse strains.
Area of Science:
- Biochemistry
- Genetics
- Molecular Biology
Background:
- DBA/2 mice are a common model for studying murine erythroleukemia.
- Understanding the genetic makeup of DBA/2 mice is crucial for erythroleukemia research.
Purpose of the Study:
- To determine the amino acid sequences of beta major and beta minor globin chains in DBA/2 mice.
- To compare these sequences with those predicted from BALB/c mouse globin genes.
Main Methods:
- Amino acid sequencing of beta globin chains.
- Comparative analysis of protein primary structure.
Main Results:
- The primary amino acid sequences of DBA/2 beta globin chains were fully elucidated.
- These sequences were found to be identical to those predicted from BALB/c beta globin genes.
Conclusions:
- The genetic loci for beta globin in DBA/2 and BALB/c mice exhibit high sequence conservation.
- This finding suggests a lack of rapid evolutionary divergence at these specific genetic loci between these inbred mouse strains.
