The following antibodies were used: CSPGs (2 μg/ml; CC117, EMD Millipore), cycloheximide (10 μg/ml; C0934, Sigma Aldrich), recombinant rat myelin-associated glycoprotein (MAG; 30 μg/ml; P07722, R&D Systems), Y-27632 ROCK inhibitor (10 μM; 1254, Tocris Bioscience), anti- αTAT1 (1:200; ab58742, Abcam), anti-HDAC6 (1:500; NB100-91805, Novus Biologicals), anti-acetylated α-tubulin (1:1000; D20G3, Cell Signaling Technology), anti-α-tubulin (1:5000; DM1A, Sigma-Aldrich), anti-β-actin (1:5000; AC-74, Sigma-Aldrich), anti-β III tubulin (1:5000; MRB435P, BioLegend) and anti-GFP (1:500; Sigma-Aldrich). Lentivirus containing GFP (control) or GFP-tagged wild-type αTAT1 constructs, under the human cytomegalovirus (CMV) promoter, was purchased from Dr. Mingjie Li (Washington University School of Medicine, St. Louis, MO; Li et al., 2010 (link)). HDAC6 activity was determined using the fluorometric HDAC6 Activity Assay kit (BioVision), as per manufacturer’s instructions.
