Crystal Structure of G protein coupled receptor kinase 6 bound to AMPPNP

The structure was published by Lodowski, D.T., Tesmer, V.M., Benovic, J.L., and Tesmer, J.J., in 2006 in a paper entitled "The Structure of G Protein-coupled Receptor Kinase (GRK)-6 Defines a Second Lineage of GRKs." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2005.

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

This PDB entry contains multiple copies of the structure of G protein-coupled receptor kinase 6.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.
