Crystal Structure of the Human Beta2-Chimaerin

The structure was published by Canagarajah, B., Leskow, F.C., Ho, J.Y., et al., Saidi, L.F., Kazanietz, M.G., and Hurley, J.H., in 2004 in a paper entitled "Structural mechanism for lipid activation of the Rac-specific GAP, beta2-chimaerin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 2004.

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

The PDB entry contains the structure of Beta2-chimaerin. This molecule has the UniProt identifier P52757 (CHIO_HUMAN)search. The sample contained 466 residues which is 99% of the natural sequence. Out of 466 residues 398 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.
