Biochemical evidence for trans complementation of structural genes in the expression of I-E antigens in F1 hybrids. 1981

M L Plunkett, and C S David, and J H Freed

Analysis of the tryptic peptides obtained from the Ia.7-positive, "I-E" antigens produced by 4 F1 combinations derived from strain A.TFR5 has provided biochemical confirmation that I-A/I-E gene complementation can occur in the transconfiguration. The data obtained support the concept that structural genes, as opposed to regulatory genes, are the essential elements involved in this complementation and support the assignment of the I-E subregion of strain A.TFR5 as I-Ek. The data support the following assignments of the genes encoding the E beta chains: B10.A(4R) as E beta k, B10.A(5R) as E beta b, and B10.HTT as E beta s. Finally, data are presented demonstrating that the E beta chain derived from the recombinant D2.GD strain partially differs from the E beta d chain derived from a conventional H-2d haplotype strain, B10.D2.

D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
