The genes coding for 20-kDa lymphotoxin (TNF-beta) and tumor necrosis factor (TNF-alpha) have been cloned from a rabbit genomic library. The two genes are tandemly arranged and separated by only 1 kb of DNA, as previously observed in human and mouse genomes. We have sequenced the entire rabbit lymphotoxin-encoding gene and inferred the primary structure of rabbit TNF-beta, whose cDNA is not yet cloned. We also analysed the upstream sequences of the rabbit TNF-beta and TNF-alpha genes and identified a number of potential binding sites for known nuclear transcription factors, and in particular several putative kappa B-type sequences.
编码20-kDa淋巴毒素(TNF-β)和肿瘤坏死因子(TNF-α)的基因已从兔基因组文库中克隆出来。这两个基因串联排列,仅被1 kb的DNA隔开,正如先前在人类和小鼠基因组中观察到的那样。我们已经对整个兔淋巴毒素编码基因进行了测序,并推断出兔TNF-β的一级结构,其cDNA尚未克隆。我们还分析了兔TNF-β和TNF-α基因的上游序列,并确定了许多已知核转录因子的潜在结合位点,特别是几个假定的κB型序列。
