    • Methods and compositions for identifying novel genes that share regions of homology with known genes from target groups of genes of interest are provided. The methods comprise systematically designing oligonucleotide primers that are specific for regions of homology within the nucleotide sequences of a target group of known genes and performing successive rounds of PCR amplification of nucleic acid material from an organism of interest. The PCR steps are intended to identify and amplify nucleic acids comprising both known and novel genes. Nucleic acid molecules comprising known genes are detected and eliminated from further consideration by dot blot analysis using oligonucleotide probes specific for the known genes in the target group. Potentially novel genes are subjected to further sequence analysis to confirm novelty and assayed for biological activity. Compositions of the present invention include novel polynucleotides, and variants and fragments thereof, that comprise novel genes and the polypeptides encoded thereby.
    • 提供了用于鉴定与来自目标基因目标组的已知基因具有同源性区域的新基因的方法和组合物。 所述方法包括系统地设计对已知基因的目标组的核苷酸序列内的同源性区域特异的寡核苷酸引物,并且从感兴趣的生物进行核酸材料的连续循环PCR扩增。 PCR步骤旨在鉴定和扩增包含已知和新型基因的核酸。 包含已知基因的核酸分子通过使用对靶基因中已知基因具有特异性的寡核苷酸探针的斑点印迹分析进一步考虑而被检测和消除。 对潜在的新基因进行进一步的序列分析以确认新颖性并测定生物活性。 本发明的组合物包括新的多核苷酸及其变体和片段,其包含新基因和由此编码的多肽。
