4GUE - PubMed Abstract: 
Members of the RSK family of kinases constitute attractive targets for drug design, but a lack of structural information regarding the mechanism of selective inhibitors impedes progress in this field. The crystal structure of the N-terminal kinase domain (residues 45-346) of mouse RSK2, or RSK2(NTKD), has recently been described in complex with one of only two known selective inhibitors, a rare naturally occurring flavonol glycoside, kaempferol 3-O-(3'',4''-di-O-acetyl-α-L-rhamnopyranoside), known as SL0101 ...
