Integrin adhesion receptors are an essential class of cell surface glycoproteins that mediate cell adhesion, migration and spreading by linking the extracellular matrix with the actin cytoskeleton. Integrin activation is regulated, in part, by the buy 256373-96-3 binding of adaptor and signaling proteins to the short integrin cytoplasmic tails. Once recruited, these proteins convert integrins to their high-affinity/ active conformations, which in turn triggers cellular responses to cell adhesion such as cell migration, differentiation and survival [1]. An important cytoplasmic component localized to integrin receptors at focal adhesions is the heterotrimeric protein complex comprised of the integrin linked kinase (ILK), parvin, and PINCH, termed the IPP complex for its member proteins. The IPP complex is essential for focal adhesion formation, and serves as a hub for integrin and growth factor signaling to control cell adhesion, spreading and migration [2]. ILK was first identified as an integrin b1 cytoplasmic tail binding protein [3], and is the central member of the IPP complex. In its N-terminus, five ankyrin repeat domains mediate direct interaction with the LIN-11/Isl1/MEC-3 (LIM)-domain containing protein PINCH1 (or the related isoform PINCH2) via 
the LIM1 domain [4?] (Figure 1A). The C-terminus of ILK contains a pseudokinase domain (which we term `pKD’) that wasthe source of a lengthy controversy concerning its putative catalytic activity. Recent structural and structure-directed studies have resolved this controversy to show a lack of enzymatic competence [9,10]. There is direct interaction between 
the ILK pseudokinase domain and the second of two tandem calponin homology (CH) domains that are present in the parvin family of proteins (a, b, and c) [11?3] (Figure 1A). It was originally reported that ILK contains a short pleckstrin homology (PH) domain (MedChemExpress Vitamin D2 residues 180?12) between the ARD and pKD regions [14]; however, subsequent structural studies revealed that the majority of this segment (residues 185?12) 1662274 is integral to the pseudokinase fold [9]. The heterotrimeric IPP complex forms in the cytoplasm prior to cell adhesion [15] and is targeted to focal adhesions by several potential mechanisms, including ILK interaction with integrin tails [3] and parvin binding to the focal adhesion protein paxillin [13,16,17]. Formation of the IPP complex also serves to stabilize and protect its members from proteasomal degradation [18,19]. Each individual component is critical for proper development, and a single deletion of either ILK, a-parvin or PINCH1 in mice causes embryonic lethality [20?3]. The IPP complex serves as a physical link between focal adhesion components, and interacts with a variety of proteins in the cytoplasm, including PINCH1 with Nck-2 [5], ILK with Kindlin-2 [24,25] and the parvins withSAXS Analysis of the IPP Complexare drawn approximately to scale.
