Nature Rev. Mol. Cell Biol. 3, 919–931 (2002)

The authors would like to apologize for the following omissions:

The following reference should have been included in the reference list: Ref. 92

Reference 92 should have been cited on page 926, right column, 2nd line, at the end of the sentence: 'Finally, downregulation of G-protein-coupled protease-activated receptor-1 (PAR1) is regulated by SNX1 (Ref. 92).'

On page 926, right column, 1st line, the abbreviation 'PARS1' should have read 'PAR1'

On page 922, Table 1, 4th column, 1st row, 'PAS1*' should have read 'PAR1*', and a definition of the acronym should have appeared in the table's footnote: PAR1, protease-activated receptor-1.

The online versions of the article have been corrected.
