Amino Acid Sequence

Arg-Gly-Asp-Ser

一般說明

四肽精氨酸-甘氨酸-天冬氨酸-丝氨酸 (RGDS) 是纤维连接蛋白细胞附着域的关键组分。最初发现 RGDS 序列可促进大鼠肾成纤维细胞 (NRKcells) 与纤连蛋白和与蛋白包覆塑料偶联的合成纤连蛋白肽结合。进一步研究表明,游离的 RGDS 肽可抑制 NRK 细胞与纤连蛋白包覆底物的结合。RGDS 序列已被证明存在于其他几种蛋白质中,如 大肠杆菌 λ受体 和辛德毕斯外壳蛋白。RGDS 也是梅毒菌梅毒螺旋体粘附的靶序列。

RGDS 已被证明可阻断纤维蛋白原诱导的完整红细胞聚集和纤维蛋白原与红细胞膜的特异性结合。已研究 RGDS 对培养的人肾小球系膜细胞中转化生长因子 ß1 (TGFß1) mRNA 表达和分泌的影响。RGDS 已被用于研究海绵藻 (Suberites domuncula) 培养细胞中整合素介导的信号转导。已证实 RGDS
可减轻结核分枝杆菌与小鼠肺泡巨噬细胞的结合

應用

Arg-Gly-Asp-Ser用于:
  • 研究其对大鼠细胞附着的影响
  • 分析纤维蛋白原与红细胞通过整合素相关受体发生的相互作用
  • 预处理细胞,评估整合素在细胞附着过程中的作用
  • 试验其与血小板分泌、纳米片吸附的蛋白竞争结合糖蛋白IIIa(GPIIIa)的情况
