项目摘要
To understand function of peroxisomes and pathogenesis of peroxisome disorders, we performed proteome analysis of rat liver peroxisomes. Further, we investigated function of novel peroxisomal proteins that we identified. Concerning peroxisome disorders, we analyzed fate of an ABC protein, ALDP that is responsible for adrenoleukodystrophy (ALD) in normal and human ALD fibroblasts. As a result, following new findings were obtained.1.We prepared rat liver peroxiomes by Nycodenz gradient centrifugation and further by immunoisolation using antibody against PMP70. We identified 65 peroxisomal proteins including 5 novel proteins in the peroxisomes by LC/MS/MS analysis after digestion of the protein bands subjected to SDS-PAGE. RAB2, VAP-A, B, which might be involved in peroxisome biogenesis were identified.2.As novel 5 peroxisomal proteins, peroxisomal isozyme of Ion protease, a bi-functional enzyme containing aminoglycoside transferase and acyl-CoA dehydrogenease domains, a homolog to endozepine-related protein, a tumor-related protein with ribonuclease domain, a homolog of CGI-135 which is required organelle fission were identified.3.We cloned the human lon protease cDNA and express Lon protease-His in E.coli. We purified the lon protease and found that the enzyme showed ATP-dependent protease activity against denatured proteins4.We identified 12 peroxin on rat liver peroxisomes. Pex3p was associated with Pex16p and Pex19p and suggested to be important for peroxisomes biogenesis.5.We found most ALDPs with missense mutations were deficient on peroxiomes of human ALD fibroblasts. In addition, the mutant proteins were found to be degraded rapidly after synthesis by proteasomes.Roles of novel peroxisomal proteins are now under investigation.
为了了解过氧化物酶体的功能和过氧化物酶体疾病的发病机制,我们对大鼠肝脏过氧化物酶体进行了蛋白质组学分析。此外,我们研究了我们鉴定的新型过氧化物酶体蛋白的功能。关于过氧化物酶体疾病,我们分析了ABC蛋白ALDP的命运,ALDP是负责肾上腺脑白质营养不良(ALD)在正常和人类ALD成纤维细胞。本研究获得了以下新发现:1.采用Nycodenz梯度离心法制备大鼠肝脏过氧化物酶体,并进一步用抗PMP 70抗体免疫分离。对SDS-PAGE电泳后的蛋白条带进行酶切后,通过LC/MS/MS分析,我们鉴定了65个过氧化物酶体蛋白,其中包括5个新蛋白。2.作为新的5种过氧化物酶体蛋白,Ion蛋白酶的过氧化物酶体同工酶是一种含有氨基糖苷转移酶和酰基辅酶A水解酶结构域的双功能酶,是一种与内分泌相关蛋白同源的蛋白,是一种具有核糖核酸酶结构域的肿瘤相关蛋白,克隆了人Lon蛋白酶cDNA,并在大肠杆菌中表达Lon蛋白酶-His。我们对该酶进行了纯化,发现该酶对变性蛋白具有ATP依赖的蛋白酶活性。Pex 3 p与Pex 16 p和Pex 19 p相关,提示Pex 3 p在过氧化物酶体生物合成中起重要作用。5.我们发现大多数错义突变的ALDP在人ALD成纤维细胞的过氧化物酶体上是缺陷的。另外,突变蛋白在蛋白酶体合成后被迅速降解,新的过氧化物酶体蛋白的作用正在研究中。
