项目摘要
In this study, we have analyzed the structural and functional diversity of the IP_3 receptor family.1.We have cloned human type 1,2, and 3 receptor cDNAs of the IP_3R family, and have studied their structures, IP_3-binding activities, expression in various tissues and cell-lines, and chromosomal loci.2.We have localized the IP_3-binding site, calmodulin binding site and two N-linked glycosylation sites on the mouse type 1 IP_3 receptor. We have proposed a membrane-spanning model and a channel pore region.3.We have studied the expression of the type 1 receptor in various cell systems ; the up-regulation during the differentiation of a HL-60 cell line toward a neutrophilic cell lineage, the down-regulation in an SH-SY5Y neuroblastoma chronically stimulated with carbacol, and the reduction in cerebella of human spinocerebellar degeneration patients (olivopontocerebellar atrophy [OPCA] and hereditary cerebellar atrophy of Holmes type).4.We have developed transgenic mice carrying the fusion gene composed of the type 1 receptor promoter and beta-galactosidase gene, by which dynamic expression of the type 1 receptor can be easily visualized by assaying beta-galactosidase activity with chromogenic substrates.5.We have studied the expression of other molecules involved in calcium increase in neuronal cells, i.e., ryanodine receptors and voltage-dependent calcium channels, and have suggested the presence of complex calcium signalling systems in the nervous system.
本研究分析了IP_3受体家族的结构和功能多样性:1.克隆了人IP_3受体家族的1、2和3型受体cDNA,并对其结构、IP_3结合活性、在不同组织和细胞系中的表达以及染色体定位进行了研究; 2.定位了IP_3结合位点,小鼠1型IP_3受体上的两个N-糖基化位点和两个钙调蛋白结合位点。我们提出了一个跨膜模型和一个通道孔区。3.我们研究了1型受体在不同细胞系统中的表达;在HL-60细胞系向嗜酸性细胞谱系分化过程中的上调,在用卡巴可长期刺激的SH-SY 5 Y神经母细胞瘤中的下调,脊髓小脑变性患者小脑的缩小(橄榄体桥脑小脑萎缩[OPCA]和Holmes型遗传性小脑萎缩)4.我们已经开发了携带由1型受体启动子和β-半乳糖苷酶基因组成的融合基因的转基因小鼠,通过该方法,可以通过测定β-半乳糖苷酶与显色底物的活性5.我们研究了参与神经元细胞中钙增加的其他分子的表达,即,Ryanodine受体和电压依赖性钙通道,并已表明在神经系统中存在复杂的钙信号系统。
