crystal structure of CISK-PX domain

The structure was published by Xing, Y., Liu, D, Zhang, R., Joachimiak, A., Songyang, Z., and Xu, W., in 2004 in a paper entitled "Structural basis of membrane targeting by the Phox homology domain of cytokine-independent survival kinase (CISK-PX)" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.6 Å and deposited in 2004.

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

The PDB entry contains the structure of Serine/threonine-protein kinase Sgk3. This molecule has the UniProt identifier Q9ERE3 (SGK3_MOUSE)search. The sample contained 154 residues which is < 90% of the natural sequence. Out of 154 residues 114 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
