The second SH3 domain from Ponsin in complex with the paxillin proline rich region

The structure was published by Gehmlich, K., Pinotsis, N., Hayess, K., et al., El Banayosy, A., Wilmanns, M., and Ehler, E., in 2007 in a paper entitled "Paxillin and ponsin interact in nascent costameres of muscle cells" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.63 Å and deposited in 2006.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Ponsin and Paxillin.
