When this article was first published, the phospholipid PIP2 was incorrectly described as phosphatidylinositol (3,4)-bisphosphate rather than as phosphatidylinositol (4,5)-bisphosphate (p. 1 of the PDF, right-hand column, line 14). This has been corrected in the current PDF and HTML versions of the article.
