The complete amino acid sequence of dog beta2-microglobulin.
Dog beta2-microglobulin was purified from the urine of dogs with potassium dichromate induced tubular damage. It was purified by sequential use of anion exchange chromatography, gel filtration chromatography, and reversed-phase high performance liquid chromatography. Comparisons of the amino acid sequence of the dog protein with human, mouse, and rabbit beta2-microglobulin, indicated a high degree of similarity. The dog protein was very similar to human beta2-microglobulin in that it had a molecular weight of 11.8 kDa and contained two half-cystinyl residues. Dog and human beta2-microglobulin were demonstrably different at 24 of the 99 positions compared. The data supported the conclusion that the purified protein was dog beta2-microglobulin and that all four proteins from dog, human, mouse, and rabbit were closely related.
