1u5s Summary


NMR structure of the complex between Nck-2 SH3 domain and PINCH-1 LIM4 domain

The structure was published by Vaynberg, J., Fukuda, T., Chen, K., et al., Ng, L., Wu, C., and Qin, J., in 2005 in a paper entitled "Structure of an ultraweak protein-protein complex and its crucial role in regulation of cell morphology and motility." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2004.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Cytoplasmic protein NCK2 and PINCH protein.

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.
