2v4l Summary

pdbe.org/2v4l
spacer

complex of human phosphoinositide 3-kinase catalytic subunit gamma (p110 gamma) with PIK-284

The structure was published by Apsel, B., Blair, J.A., Gonzalez, B., et al., Williams, R.L., Shokat, K.M., and Knight, Z.A., in 2008 in a paper entitled "Targeted Polypharmacology: Discovery of Dual Inhibitors of Tyrosine and Phosphoinositide Kinases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2008.

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

The PDB entry contains the structure of PHOSPHATIDYLINOSITOL-4,5-BISPHOSPHATE 3-KINASE CATALYTIC SUBUNIT GAMMA ISOFORM. This molecule has the UniProt identifier P48736 (PK3CG_HUMAN)search. The sample contained 966 residues which is < 90% of the natural sequence. Out of 966 residues 844 were observed and are deposited in the PDB.

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 is most likely monomeric.
