There was an error published in Development131, 425-434.

On page 428, the description of the rbe-1 mutation and its position as depicted in Fig. 2B were incorrect. The correct description is as follows. In rbe-1, a C to T transversion at nucleotide position 241 in the cDNA sequence results in the replacement of an arginine with a stop codon at amino acid 81 in the RBE protein.
