    • Isolated mammalian thrombopoietins are disclosed. The thrombopoietins include polypeptides characterized by an amino acid sequence selected from the group consisting of (a) a sequence of amino acids as shown in SEQ ID NO:2 having an amino terminus at Ser(45) and a carboxyl terminus between Ser(208) and Asn(216), inclusive; a sequence of amino acids as shown in SEQ ID NO:4 having an amino terminus at Ser(22) and a carboxyl terminus between Arg(185) and Asn(193), inclusive; a sequence of amino acids as shown in SEQ ID NO:4 having an amino terminus at Ser(22) and a carboxyl terminus at Arg(198); a sequence of amino acids as shown in SEQ ID NO:4 having an amino terminus at Ser(22) and a carboxyl terminus at Phe(207); and allelic variants of (a)-(d). Also disclosed are isolated DNA molecules encoding these polypeptides as well as vectors, cells and methods that can be used for the production of the polypeptides.
    • 公开了分离的哺乳动物血小板生成素。 血小板生成素包括以氨基酸序列为特征的多肽,所述氨基酸序列选自(a)SEQ ID NO:2所示氨基酸序列,其具有Ser(45)的氨基末端和Ser(208)之间的羧基末端, 和Asn(216)(含); 如SEQ ID NO:4所示的氨基酸序列,其具有Ser(22)的氨基末端和Arg(185)和Asn(193)之间的羧基末端(包括端值); 如SEQ ID NO:4所示的氨基酸序列,其在Ser(22)具有氨基末端,在Arg处具有羧基末端(198); 如SEQ ID NO:4所示的氨基酸序列,其在Ser(22)具有氨基末端,在Phe(207)具有羧基末端; 和(a) - (d)的等位变体。 还公开了编码这些多肽的分离的DNA分子以及可用于产生多肽的载体,细胞和方法。
