Kinase and Ubiquitin-associated domains of MARK3/Par-1

The structure was published by Murphy, J.M., Korzhnev, D.M., Ceccarelli, D.F., et al., Sicheri, F., Kay, L.E., and Pawson, T., in 2007 in a paper entitled "Conformational instability of the MARK3 UBA domain compromises ubiquitin recognition and promotes interaction with the adjacent kinase domain" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 2007.

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

This PDB entry contains multiple copies of the structure of MAP/microtubule affinity-regulating kinase 3.
