Talin

Talin is involved in cell-cell contacts. It links integrins to actin. It contains a C-terminal rod domain with integrin binding sites (IBS) and actin binding sites (ABS) and N-terminal FERM domain with subdomains F0-F3. The F3 subdomains interacts with integrin. Talin contains 3 Vinculin binding sites VBS1-VBS3. The images at the left and at the right correspond to one representative Talin, i.e. the crystal structure of mouse Talin rod (2x0c).
