This Article contains typographical errors.

In Table 1 under ‘Förster distance with mEGFP (nm)’, the sREACh and ShadowG values should read 6.2 and 5.1 respectively.

In addition, in the Materials and Methods section under subheading ‘Plasmid construction’,

‘For construction of mCherry-ERK2 and MEK1 plasmids, the source pCMV5-ratERK2-WT and EYFP-ERK2 plasmids were provided by Natalie Ahn (Addgene plasmid # 40812)29 and by Akihiko Yoshimura, respectively. mCherry and ERK2 or MEK1 was subcloned into the modified pmEGFP-C1, replacing mEGFP’.

should read:

‘For construction of mCherry-ERK2 and MEK1 plasmids, the source pCMV5-ratERK2-WT and EYFP-MEK1 plasmids were provided by Natalie Ahn (Addgene plasmid # 40812)29 and by Akihiko Yoshimura, respectively. mCherry and ERK2 or MEK1 was subcloned into the modified pmEGFP-C1, replacing mEGFP’.
