spacer

P395S mutant of the p85 regulatory subunit of the N-terminal src homology 2 domain of PI3-Kinase complexed to a peptide derived from PDGFr

The structure was published by Guenther, U.L., Weyrauch, B., Zhang, X., and Schaffhausen, B., in 2003 in a paper entitled "Nuclear magnetic resonance structure of the P395S mutant of the N-SH2 domain of the p85 subunit of PI3 kinase: an SH2 domain with altered specificity" (abstract).

The structure was determined using NMR spectroscopy and deposited in 2003.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Phosphatidylinositol 3-kinase regulatory alpha subunit and 8-mer peptide from PDGFr.

The molecule most likely forms heterodimers.
