This article has been updated

Phosphoinositide 3-OH kinases (PI(3)Ks) are important lipid signaling enzymes and exciting drug targets for a number of human diseases. The first, much anticipated crystal structure of the delta isoform of PI(3)K provides surprising new insights into the selectivity of inhibitors for this versus other PI(3)K isoforms and facilitates the design of improved drugs.

    In the version of this article initially published, there was an error in the chemical structure of IC87114 that arose from the coordinates used to generate Figure 1a. The corrected structure has been deposited by Berndt et al. to the Protein Data Bank (PDB code 2X38). Figure 1a and the PDB code in the figure legend have been corrected in the HTML and PDF versions of the article.
