Correction to "Preferential formation of MT1/MT2 melatonin receptor heterodimers with distinct ligand interaction properties compared with MT2 homodimers"

In the above article [Ayoub MA, Levoye A, Delagrange P, andJockers R (2004) Mol Pharmacol 66:312–321], informationregarding the ligands in Fig. 5 was removed in error duringcopyediting. A corrected version of Fig. 5 appears below. Theonline version has been corrected in departure from the printversion.

Fig. 5. Correlations between EC₅₀ values of MT₁/MT₂ heterodimers and K_i values of MT₁ and MT₂ receptors. EC₅₀ values of the MT₁/MT₂ heterodimer shown in Table 4 were plotted against K_i values determined in cells coexpressing MT₁ and MT₂ receptors (A) or expressing MT₁-Rluc (B) or MT2-YFP (C) receptors individually. D, correlation between EC₅₀ values of the MT₂ homodimer and the MT₁/MT₂ heterodimer. Ligands: 1, melatonin; 2, S20098 [GenBank] ; 3, S22153 [GenBank] ; 4, S20928; 5, 4P-PDOT; 6, luzindole; 7, S24773; 8, 2-iodomelatonin. B and C, nonselective (

) and selective ( ${circ}$ ) compounds. Ligand 9 shown in B corresponds to the MT₁-selective S26284 [GenBank] compound. Data were fitted using a linear regression equation (GraphPad Prism software).
