Structural Basis for Differential Recognition of Tyrosine Phosphorylated Sites in the Linker for Activation of T cells (LAT) by the Adaptor Protein Gads

The structure was published by Cho, S., Velikovsky, C.A., Swaminathan, C.P., Houtman, J.C., Samelson, L.E., and Mariuzza, R.A., in 2004 in a paper entitled "Structural basis for differential recognition of tyrosine-phosphorylated sites in the linker for activation of T cells (LAT) by the adaptor Gads." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2003.

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