2.0A X-ray structure of C-terminal kinase domain of p90 ribosomal S6 kinase 2 (RSK2)
Overview
The X-ray structure at 2.0-A resolution of the p90 ribosomal S6 kinase 2, C-terminal kinase domain revealed a C-terminal autoinhibitory alphaL-helix, that was embedded in the kinase scaffold and determines the inactive, kinase conformation. We suggest a mechanism of activation through, displacement of the alphaL-helix and rearrangement of the conserved, residue Glu500, as well as the reorganization of the T-loop into the, active conformation.
About this Structure
2QR8 is a Single protein structure of sequence from Mus musculus with as ligand. Active as Non-specific serine/threonine protein kinase, with EC number 2.7.11.1 Full crystallographic information is available from OCA.
