    • A nucleic acid which can be used to express a polypeptide with interleukin-16 activity in a prokaryotic or eukaryotic host cell, wherein in the region coding for the said polypeptide the said nucleic acid a)corresponds to the DNA sequence of nucleotides 54-1175 from SEQ ID NO:1 or to its complementary strand, b) hybridizes with the DNA of nucleotide sequence 54-785 from SEQ ID NO:1 under stringent conditions, c) hybridizes with the DNA of nucleotide sequence 786-1175 from SEQ ID NO:1 under stringent conditions and at the 5′ end begins with nucleotides 756-785 from SEQ ID NO:1 or a part thereof which codes for part of the sequence of amino acids 235-244 from SEQ ID NO:1 or d) it is a nucleic acid sequence which would hybridize under stringent conditions with the nucleic acid sequences defined by a) or b) without the degeneracy of the genetic code, codes for proteins with improved interleukin-16 activity.
    • 可用于在原核或真核宿主细胞中表达具有白细胞介素-16活性的多肽的核酸,其中在编码所述多肽的区域中,所述核酸a)对应于核苷酸54-1175的DNA序列, SEQ ID NO:1或其互补链,b)在严格条件下与SEQ ID NO:1的核苷酸序列54-785的DNA杂交,c)与SEQ ID NO:1的核苷酸序列786-1175的DNA杂交, 1在严格条件下和5'末端以SEQ ID NO:1的核苷酸756-785或编码SEQ ID NO:1的氨基酸235-244的部分序列的部分开始,或d)它是 在严格条件下与在a)或b)中定义的核酸序列杂交但不具有遗传密码简并性的核酸序列,编码具有改善的白细胞介素-16活性的蛋白质。
