NMR STRUCTURE OF THE N-SH2 DOMAIN OF THE P85 SUBUNIT OF PI3-KINASE

The structure was published by Weber, T., Schaffhausen, B., Liu, Y., and Gunther, U.L., in 2000 in a paper entitled "NMR structure of the N-SH2 of the p85 subunit of phosphoinositide 3-kinase complexed to a doubly phosphorylated peptide reveals a second phosphotyrosine binding site." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2000.

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

The PDB entry contains the structure of PHOSPHATIDYLINOSITOL 3-KINASE REGULATORY ALPHA SUBUNIT. This molecule has the UniProt identifier Q63787 (P85A_RAT)search. The sample contained 111 residues which is < 90% of the natural sequence. Out of 111 residues 111 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
