The extracellular matrix (ECM) is a complex structure of secreted macromolecules surrounding mammalian organs and tissues. Controlled interactions between cells and the ECM are important in proliferation, migration, survival, polarity, and differentiation. Cells contact the ECM primarily through focal adhesion complexes, which contain integrins, as well as multiple adaptor and signaling proteins (1). The ILK/PINCH/Parvin (IPP) adaptor complex acts at the interface of the integrin/actin connection to regulate formation of focal adhesions and integrin signaling. Roles for IPP proteins outside of the IPP complex have been proposed, including regulation of gene expression (2,3). 
 PINCH, also known as LIMS1, has been shown to function as a specific regulator of gene expression in glomerular podocytes in response to TGF-β1 (4). Researchers have shown that PINCH is highly expressed in some human tumors, and that PINCH can promote resistance to ionizing radiation through activation of Akt (5,6).

细胞外基质(ECM)是存在于哺乳动物器官和组织周围的一种复杂的大分子结构。细胞和细胞外基质之间的相互作用对于细胞增殖、移动、存活、极性和分化均有非常重要的作用。细胞最初通过膜内在的异二聚体整合素传递信息。整合素将细胞外基质与细胞骨架连接,进而通过局部的粘附分子蛋白复合物传递细胞信号机制(1)。ILK/PINCH/Parvin (IPP)连接复合物在整合素/肌动蛋白的之间调节局部粘附分子的形成及整合素的信号转导中起作用。IPP复合物之外的IPP蛋白作用已经被提及,包括调节基因表达(2,3)。PINCH,也被认为是LIMS1,被认为是一种特殊的基因表达调节蛋白,在肾小球足细胞中对TGF-β1应答(4)。研究者表明PINCH在一些人肿瘤中高度表达,PINCH能够通过激活Akt提高对电离辐射的抵抗力(5,6)。
