Erratum: Corrigendum: 3′ UTR seed matches, but not overall identity, are associated with RNAi off-targets

Nat. Methods 3, 199–204 (2006). In Figure 3 of the original article, the genes in panels a–c were incorrectly identified. The correct gene names are: (a) Ppyr/LUC siRNA A, (b) ALPPL2 and (c) Ppyr/LUC siRNA B. The figure legend should read: Figure 3 | Systematic single base pair–mismatch analysis of siRNA functionality.
