Crystal Structure of human vinculin head domain (residues 1-252) in complex with alpha-catenin (residues 277-382)

The structure was published by Rangarajan, E.S. and Izard, T., in 2012 in a paper entitled "alpha-Catenin unfurls upon binding to vinculin" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.66 Å and deposited in 2012.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely Vinculin and Catenin alpha-1.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterodimers.
