Background
The ILK/PINCH/Parvin (IPP) complex is composed of three highly conserved proteins recruited to sites of ECM contact as pre-assembled structures. The IPP acts at the interface of the integrin/actin connection to regulate formation of focal adhesions and integrin signaling. All three proteins contain multiple protein binding domains allowing them to function as adaptor proteins in the formation of focal adhesions. ILK (integrin-linked kinase) also has a catalytic (protein Ser/Thr kinase) domain, and may or may not function as a kinase in vivo. Roles for IPP proteins outside of the IPP complex have been proposed, including regulation of gene expression (2,3).
The parvin family consists of 3 members, α-parvin/actopaxin, β-parvin/affixin, and γ-parvin. α-parvin and β-parvin are expressed ubiquitously, while expression of γ-parvin is restricted to hematopoietic cells (4). α-parvin binds to f-actin both directly and via interaction with the focal adhesion protein paxillin (5). α-parvin regulates cell spreading and motility through interactions with the cofilin kinase TESK1 (6), and with the GTPase activating protein CdGAP (7). Phosphorylation of α-parvin during mitosis may have a role in the regulation of actin dynamics during the cell cycle (8).
