  • 摘要:Primary structural analyses of beta 3-microglobulin isolated from the tumor cell lines EL4.BU (derived from a C57BL/6 mouse) and C14 (derived from a BALB/c mouse) have revealed the presence of an amino acid difference at position 85 of this molecule. beta 2-Microglobulin isolated from histocompatibility antigens of EL4.BU has alanine at this position, whereas that from C14 has aspartic acid. Determination of the sequence of these molecules has employed radiochemical methodology that was developed in studies of murine histocompatibility antigens. The sequence obtained in this study is: Ile - Gln - Lys - Thr - Pro - Gln - Ile - Gln - Val - Tyr - Ser - Arg - His - Pro - Pro - Glu - Asn - Gly - Lys - Pro - Asn - Ile - Leu - Asn - Cys - Tyr - Val - Thr - Gln - Phe - His - Pro - Pro - His - Ile - Glu - Ile - Gln - Met - Leu - Lys - Asn - Gly - Lys - Lys - Ile Pro - Lys - Val - Glu - Met - Ser - Asp - Met - Ser - Phe - Ser - Lys - Asp - Trp - Ser - Phe - Tyr - Ile - Leu - Ala - His - Thr - Glu - Phe - Thr - Pro - Thr - Glu - Thr - Asp - Thr - Tyr - Ala - Cys - Arg - Val - Lys - His - Ala/Asp - Ser - Met - Ala - Glu - Pro - Lys - Thr - Val - Tyr - Trp - Asp - Arg - Asp - Met. Comparison of the sequence of murine beta 2-microglobulin to the sequences reported for the homologues from man, rabbit, and guinea pig indicate identities of 68%, 66%, and 61%, respectively.
