Reciprocal phosphorylation between SOBIR1 and BAK1
(A) Determination of the oligomerization states of SOBIR1-KD, BAK1-CD, and SOBIR1-KD incubated with BAK1-CD via SEC. The reaction mixture contained 30 μM SOBIR1-KD and 10 μM GST-BAK1-CD. Elution volumes of the protein standards are indicated.
(B) Western blotting analysis of the transphosphorylation of PP2Cα-dephosphorylated SOBIR1-KD by wild-type BAK1-CD. The reaction mixture contained 10 μM dSOBIR1-KD and 1 μM GST-BAK1-CD.
(C) Western blotting analysis of the transphosphorylation of BAK1-CDD434N by wild-type SOBIR1-KD. The reaction mixture contained 10 μM GST-BAK1-CDD434N and 1 μM SOBIR1-KD.
