TDP-43 is specifically phosphorylated by MEK at Thr-153/Tyr-155. A, human TDP-43 amino acid sequence surrounding Thr-153 and Tyr-155 (underlined) aligned with the human ERK1 activation loop sequence where MEK phosphorylates at Thr-202 and Tyr-204 (underlined). B, immunoblots of heat shock and control treated HEK-293 and SH-SY5Y cells. The levels of phospho-independent proteins are shown and tubulin was used as loading control. C, SH-SY5Y cells treated with specific MEK inhibitors PD184352 (10 μm) and PD98059 (50 μm), and with a specific inhibitor of the downstream kinase ERK FR180204 (30 μm). Cells were exposed to heat shock following 1 h of inhibitor treatment. D, SH-SY5Y cells treated with the protein phosphatase PP1/2A inhibitor, okadaic acid (0.5 μm), combined with the MEK inhibitor PD184352 for 1 h before heat shock. E, p-T153/Y155 levels analyzed upon expression of the constitutively active GFP-MEK_DD mutant and a GFP control construct in SH-SY5Y cells in the absence of heat shock.

Phosphomimetic substitutions at Thr-153/Tyr-155 modulate TDP-43 activity. A, schematic representation of the CFTR exon 9 mini-gene cellular reporter of TDP-43 activity. Exons and intron regions are represented as boxes and lines, respectively. TDP-43 binding to UG repeats (UG13) near the 3′ splice site inhibits exon 9 inclusion. The two major products of splicing are shown to the right. B, RNAi-resistant (siRes) TDP-43 mutants were expressed in siRNA-treated HeLa cells. Relative TDP-43 activity was calculated comparing wild-type siRes. The effect of the RNA binding-deficient mutant, F147L/F149L, was used as control. Error bars, S.D., n > 5. C, constitutively active MEK_DD, or control GFP vector, expressed in siRNA or control treated cells. Reporter activity was analyzed relative to siRes wild-type (WTsiR). Values represent the averages of independent transfection experiments. Error bars, S.D., n ≥ 4.

Fluorescence-based assay to measure TDP-43 RNA binding affinity for GU-repeats. A, intrinsic fluorescence (F) of recombinant TDP-43 upon titration of A(UG)6 RNA normalized by the fluorescence in the absence of RNA (F0). Shown are F/F0 values at four different TDP-43 concentrations and data were analyzed according to Equations 1 and 2 under “Experimental Procedures.” The best fit values for the apparent equilibrium dissociation constant, Kd(app), are shown in Table 1. B, schematic representation of full-length TDP-43 highlighting Trp-113 and Trp-172 in RRM1. Lower panel shows the surface and ribbon representation of the 102–269 fragment bound to GU-rich RNA (36). Tryptophan residues in RRM1 are highlighted in magenta.
