Complete amino acid sequences of bovine thymopoietins I, II, and III: closely homologous polypeptides.
Complete amino acid sequences were determined for thymopoietins I and II (revision), isolated from bovine thymus, and for thymopoietin III, a newly identified polypeptide isolated from bovine spleen. Thymopoietin III (TP-III) is a 49 amino acid monomeric peptide that shows minor microheterogeneity at residue 34. The three thymopoietins have largely identical sequences yet some distinct differences, suggesting very recent evolution from a common gene. The complete amino acid sequences are (Formula: see text).
