ATP-STD NMR takes advantage of Mg2+ binding to ATP to adjust the ATP affinity for protein kinases permitting a wide range of Ki's to be determined for ATP competitive ligands. Substituting Mn2+ for Mg2+ creates a paramagnetic probe (MnATP) from which the proximity of non-ATP competitive ligands can be inferred. Internal standards and references are used to reduce false positives due to protein or compound degradation. Use of the natural ATP ligand confers active site-specificity that is not available a priori from other ligand binding experiments.

High-throughput screening of libraries containing compounds of 'drug-like' molecular weight has frequently resulted in no or poor drug candidates, especially when screening against demanding drug targets such as protein-protein interactions. Fragment-based lead discovery and optimization has evolved as a...

Postdoctoral Position "Solution Dynamics of Protein Kinases" in New York
A postdoctoral position to study the solution dynamics and structure
of protein kinases is available on a NIH funded project (REF#:
HS-R-6453-10-08-S). Our group is interested in how static and dynamic
changes of protein structure affect the activity of protein kinases.
We combine X-ray crystallography, NMR and ligand binding kinetics with
collaborative molecular dynamic studies (See e.g. ref 1 and 2). Our
research group is located at Stony Brook University in a highly
interactive environment with the New York...
