3c4x Summary


Crystal Structure of G protein coupled receptor kinase 1 bound to ATP and magnesium chloride at 2.9A

The structure was published by Singh, P., Wang, B., Maeda, T., Palczewski, K., and Tesmer, J.J., in 2008 in a paper entitled "Structures of rhodopsin kinase in different ligand states reveal key elements involved in G protein-coupled receptor kinase activation." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2008.

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

This PDB entry contains multiple copies of the structure of Rhodopsin kinase.

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 most likely forms homodimers.
