It has been seen that Arabidopsis genome carries 58 genes encoding NLR-like proteins lacking the LRR or even NB-ARC sequences [27,28]. A study showed, Arabidopsis Resistance to Powdery Mildew 8 or RPW8 protein consisting of a CC domain and lacking NB-ARC and LRR sequences, to confer ...
More is known of the structure and function of the NBS domain, which is also called the NB-ARC (nucleotide binding adaptor shared by NOD-LRR proteins, APAF-1, R proteins and CED4) domain. This domain contains several defined motifs characteristic of the 'signal transduction ATPases with num...
NBS结构域,也称为NB-ARC结构域,其因在动物的NOD-LRR蛋白,哺乳动物细胞凋亡蛋白酶激活因子 Apaf-1(Apoptotic protease-activating factor-1),植物R基因编码的抗病蛋白和秀丽线虫的细胞死亡蛋白CED-4(Caenorhabditis elegans death-4 protein)(Van der Biezen&Jones,1998)中高度保守而得名。该结构域约有 300个氨基酸...
该基因全长为3116bp,包含一个2826bp的开放读码框,编码包含941个氨基酸残基的蛋白质;其氨基酸序列含有典型的NBS-LRR类抗病基因所具有的NB-ARC结构域。Blast分析发现MdNBS-LRR1与大豆NBS-LRR类抗性蛋白具有较高的氨基酸序列一致性(60%)。RT-PCR分析结果表明,MdNBS-LRR1在‘嘎啦’苹果的幼叶、茎、功能叶、芽、...
摘要: NBS-LRR类基因家族是植物抗病R基因(Resistance gene)数量最多的一类, 具有NBS (Nucleotide-binding site)和LRR (Leucine-leucine-repeat)结构域。甘薯(Ipomoea batatas)栽培种基因组已完成测序, 但尚未注释, 本研究对甘薯 基因组序列进行外显子预测, 得到甘薯染色体组全基因组蛋白序列, 在此基础上进一步对NBS...

NLRP3 is a tripartite protein that contains an amino-terminal pyrin domain (PYD), a central oligomerization domain (NB-ARC or domain present in NAIP, CIITA, HET-E and TP1 (NACHT) that presents ATPase activity, and a carboxy-terminal leucine-rich repeat domain (LRR domain). ...
