Primary structure of two nonallelic beta-globin chains from DBA/2 mice

The amino acid sequences of the beta major and beta minor globin chains from DBA/2 mice have been determined. This information is of interest because DBA/2 mice are the strain of origin for most murine erythroleukemia lines. The primary structure of DBA/2 beta globins agrees completely with that predicted from the coding properties of BALB/c beta globin genes. This identity does not support a rapid evolutionary divergence in inbred mouse strains, at least at these loci in these strains.
