1rkc Summary


Human vinculin head (1-258) in complex with talin's vinculin binding site 3 (residues 1944-1969)

The structure was published by Izard, T., Evans, G., Borgon, R.A., Rush, C.L., Bricogne, G., and Bois, P.R., in 2004 in a paper entitled "Vinculin activation by talin through helical bundle conversion" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 2003.

The experimental data on which the structure is based was not deposited.
