In the article “Bipartite Interaction between Neurofibromatosis Type I Protein (Neurofibromin) and Syndecan Transmembrane Heparan Sulfate Proteoglycans” by Yi-Ping Hsueh, Anne M. Roberts, Manuela Volta, Morgan Sheng, and Roland G. Roberts, which appeared on pages 3764–3770 of the June 1, 2001 issue, “In B, the same protein samples were used to analyze the subcellular fractionation of neurofibromin, syndecan-3, CASK, and PSD-95. The CASK and syndecan-3 immunoblots have been previously published (Hsueh and Sheng, 1999)” is added to the end of legend of Figure 3 to clarify that the panels of CASK and Synd-3 immunoblots shown in Figure 3B had been previously published as panels CASK and Syn-3C-2 in Figure 3A of the article “Regulated Expression and Subcellular Localization of Syndecan Heparan Sulfate Proteoglycans and the Syndecan-Binding Protein CASK/LIN-2 during Rat Brain Development” by Yi-Ping Hsueh and Morgan Sheng, which appeared on pages 7415–7425 of the September 1, 1999 issue. The panels “Synd-3” and “Syn-3C-2” in these two papers are identical data showing the subcellular fractionation of syndecan-3 in brain tissue. The different labeling of the identical immunoblots is because two different syndecan-3 antibodies named Syn-3ecto and Syn-3C-2 (which recognize extracellular and C-terminal domains in syndecan-3, respectively) were used in the Hsueh and Sheng 1999 study. In the 2001 paper, only the Syn-3C-2 antibody was used for immunoblotting of syndecan-3. To simplify the figure labeling in Figure 3B of the Hsueh et al. 2001 paper, we labeled it as Synd-3 instead of Syn-3C-2. This correction does not affect the conclusions of the paper.
