过氧化物酶体是一种在脂质代谢中具有重要功能的亚细胞器,几乎存在于所有的真核细胞中。过氧化物酶体膜含有许多参与过氧化物酶体基质蛋白的输入和代谢物跨膜转运的整合和外周膜蛋白。大鼠过氧化物酶体中最丰富的过氧化物酶体膜蛋白(Pmp)是Pmp 22,一种由Pxmp 2基因编码的未知功能的22 kDa蛋白。为了研究Pxmp 2基因的功能,我们启动了小鼠敲除研究。用北方印迹法检测Pxmp 2 mRNA在小鼠体内的表达水平。Pxmp 2 RNA显示出差异表达,在肝脏、肾脏和心脏组织中表达水平最高。与其他过氧化物酶体标记基因的比较显示,Pxmp 2,Pmp 70(Pxmp 1)和过氧化氢酶的表达是独立调节的。利用5′和3′ RACE技术,我们克隆了鼠Pxmp 2的全长cDNA,其包含863个核苷酸,并分离了含有整个鼠Pxmp 2的基因组克隆。我们已经分析了完整的内含子/外显子结构的Pxmp 2基因,其中包含5个外显子跨越约11 kb的基因组克隆。所有内含子/外显子剪接点都符合GT/AG规则。对Pxmp 2 5′侧翼区的序列分析表明,它没有TATA盒,但在转录起始位点上游250个碱基对内鉴定出特征性启动子元件。使用小鼠/仓鼠辐射杂交面板,Pxmp 2定位于小鼠5号染色体上59 cM处。
Peroxisomes are subcellular organelles with important functions in lipid metabolism that are found in virtually all eucaryotic cells. The peroxisomal membrane contains a number of integral and peripheral membrane proteins involved in the import of peroxisomal matrix proteins and the transport of metabolites across the membrane. The most abundant peroxisomal membrane protein (Pmp) in rat peroxisomes is Pmp22, a 22 kDa protein of unknown function that is encoded by the Pxmp2 gene. To investigate the function of the Pxmp2 gene, we have initiated mouse knockout studies. The expression level of the Pxmp2 mRNA in mice was investigated by Northern blot analysis. Pxmp2 RNA was shown to be differentially expressed with highest expression levels in liver, kidney and in heart tissue. Comparison with other peroxisomal marker genes revealed that the expression of Pxmp2, Pmp70 (Pxmp1) and catalase was regulated independently. Using 5′ and 3′ RACE we have cloned the full-length cDNA of murine Pxmp2 which comprises 863 nucleotides and have isolated a genomic clone containing the entire murine Pxmp2. We have analyzed the complete intron/exon structure of the Pxmp2 gene which contains five exons spanning about 11 kb on the genomic clone. All intron/exon splice junctions conform to the GT/AG rule. Sequence analysis of the Pxmp2 5′ flanking region revealed that it was devoid of a TATA box, but characteristic promoter elements were identified within 250 base pairs upstream of the transcriptional start site. Using a mouse/hamster radiation hybrid panel, Pxmp2 was localized on mouse chromosome 5 at 59 cM.
