采用简并PCR技术和常规筛选程序相结合的方法,我们从小鼠皮肤中分离到一种编码新型脂氧合酶的cDNA,命名为表皮型脂氧合酶-3(e-LOX-3,基因符号Aloxe 3)。Aloxe 3 mRNA在皮肤、舌和前胃的复层上皮中表达。该cDNA编码711个氨基酸的蛋白质,计算分子量为80.6 kDa。氨基酸序列显示与最近鉴定的12(R)-脂氧合酶约54%的同一性。序列比较显示,41个氨基酸残基的一段定位在分子的N-和C-末端结构域序列之间的边界附近,这也是12(R)-脂氧合酶的特征的结构特征,表明这两种表皮衍生的脂氧合酶可能是哺乳动物脂氧合酶的新结构类别的成员。新的脂氧合酶基因由15个外显子和14个内含子组成,全长22.3kb。通过种间回交分析,将该新基因定位于小鼠11号染色体的中央区。
Using a combination of degenerate PCR technique and conventional screening procedures, we isolated a cDNA encoding a novel lipoxygenase, termed epidermis-type lipoxygenase-3 (e-LOX-3, gene symbol Aloxe3), from mouse skin. Aloxe3 mRNA is expressed in the stratified epithelia of skin, tongue, and forestomach. The cDNA encodes a protein of 711 amino acids with a calculated molecular mass of 80.6 kDa. The amino acid sequence shows approximately 54% identity to the recently identified 12(R)-lipoxygenase. Sequence comparison revealed a segment of 41 amino acid residues localized near the boundary between the N- and the C-terminal domain sequences of the molecule, a structural feature that is also characteristic of 12(R)-lipoxygenase, suggesting that these two epidermis-derived lipoxygenases may be members of a novel structural class of mammalian lipoxygenases. The novel lipoxygenase gene is divided into 15 exons and 14 introns, spanning 22.3 kb of genomic DNA. By interspecific backcross analysis, the novel gene was localized to the central region of mouse chromosome 11.
