Cytohesin-1 | Sec7 domain binds to cytoplasmic tail of integrin β2 | Affecting the PI3 K-dependent activation of integrin β2 | Regulating human polymorphonuclear neutrophil | |
FAK | Directly binding to integrin β1 tail | Playing an essential role in integrin-stimulated signaling mechanism | Important for tumor progression in cancer | Sun et al. (2014) |
ILK | C-terminus of ILK binding to the cytoplasmic tails of integrin β1 and β3 | Regulating actin cytoskeleton by interacting with various actin-binding actin regulatory proteins and mediating the integrin-dependent signaling | Playing an important function to upregulate several types of cancers, as leukemia | |
β3-endonexin | Binding to integrin β3 cytoplasmic tail (Asn-IIe-Thr-Tyr (NITY) motif) | Increasing integrins affinity for ligand | Playing roles in proliferative disease, for example atherosclerosis. | Hannigan et al. (1996) |
ICAP-1 | C-terminal region containing a PTB domain that providing a binding site for integrin β1 | Acting as a messenger that transmits information to the cellular nucleus for controlling gene expression and cell proliferation in a β1-independent manner | Important for body development and pathogenesis | |
Rack1 | Interacting with the cytoplasmic tails of integrin β1, β2, and β5 | Important in the control of integrin-dependent PKC associated signaling cascades | Serving as a scaffold protein in promoting angiogenesis | |
