Characterization of the murine corticosteroid binding globulin: variations between mammalian forms.
Corticosteroid binding globulin (CGB) from term-pregnant mouse serum was isolated and characterized by peptide analysis after treatment with CNBr and Lys-specific protease, respectively. Amino acid sequence analysis of six segments, covering 189 of 383 positions in different regions of the protein, showed unexpectedly low overall homology (60%) to the indirectly deduced human amino acid sequence previously reported. However, some segments displayed a greater resemblance to their human counterparts. Differences were observed in at least two of six potential glycosylation sites. The nature of electrophoretic CBG variants and their immunological properties are described.
