General description
Gly-Arg-Gly-Asp-Ser-Pro-Lys是一种RGD肽。作为胞外基质(ECM)蛋白中的天然RGD肽，参与促进整合素介导的细胞与基质蛋白的黏附。RGD肽在细胞黏附蛋白（如纤连蛋白和玻连蛋白）中以重复形式存在。这种三肽被细胞中特定的整合素（如β1、β3和β5亚基）识别，存在于细胞表面，通过粘着斑(FA)复合物与肌动蛋白丝关联。
Application
Gly-Arg-Gly-Asp-Ser-Pro-Lys（RGD肽）已用于
- 作为抑制肽抑制整合素和纤连蛋白的结合
- 通过猪滋养外胚层粘附实验研究TGFβ（转化生长因子）对细胞粘附的影响
- 培养MC3T3-E1成骨细胞，通过AFM（原子力显微镜）检测其对细胞粘附的影响作用
- 制备RGD.Flt23k.NR纳米颗粒
- 确定RGD-整合素连接在细胞粘附过程中的参与
Biochem/physiol Actions
结合整合素的纤连蛋白类似物。

Organised nanotopography mimicking the natural extracellular matrix can be used to control morphology, cell motility, and differentiation. However, it is still unknown how specific cell types react with specific patterns. Both initial adhesion and preferential cell migration may be important

In pigs, expression and amounts of biologically active TGFbetas at the conceptus-maternal interface increase significantly as conceptuses elongate and begin the implantation process. Before their activation, secreted TGFbetas are noncovalently associated with their respective, isoform-specific latency-associated peptides (LAPs), which contain

Since osteoblast proliferation is critical for bone development, the effect of bone extracellular matrix (ECM) proteins on osteoblast signaling and proliferation in serum-free medium was investigated. Proliferation was highest in primary rat calvarial osteoblasts cells grown on fibronectin but less

The secretion of fibronectin by differentiating osteoblasts and its accumulation at sites of osteogenesis suggest that fibronectin participates in bone formation. To test this directly, we determined whether fibronectin-cell interactions regulate progressive differentiation of cultured fetal rat calvarial osteoblasts. Spatial
