Phosphorylation of SOX9 by Cyclic AMP-Dependent Protein Kinase A Enhances SOX9's Ability To Transactivate a Col2a1 Chondrocyte-Specific Enhancer

Vol. 20, no. 11, p. 4149–4158, 2000. Some of the amino acid residues in the partial SOX9 sequence shown in Fig. 2 were misnumbered due to the erroneous computation of 30 additional residues that were not present in the SOX9 sequence. Thus, “serine 211” should read “serine 181” throughout.

Page 4151, column 2: Figure 2 should appear as shown below.

Page 4151, legend to Fig. 2, line 2: “216” should read “186.”
