1m27 Summary


Crystal structure of SAP/FynSH3/SLAM ternary complex

The structure was published by Chan, B., Lanyi, A., Song, H.K., et al., Sumegi, J., Terhorst, C., and Eck, M.J., in 2003 in a paper entitled "SAP couples Fyn to SLAM immune receptors." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2002.

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

This PDB entry contains a complex of 3 biomacromolecules, namely SH2 domain protein 1A, Signaling lymphocytic activation molecule, and Proto-oncogene tyrosine-protein kinase FYN.

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 heterotrimers.
