1 Previous studies have shown that p42(mapk/erk2) phosphorylates Ser and Thr residues (T236, S240, S244, and S270) in the membrane proximal region of TNF-R1 and that mutation of these residues to Glu and Asp residues (TNF-R1.4D/E) mimics the effect of phosphorylation on receptor signaling and localization.

2 Incubation of Sepharose bead-bound GST-TNF-R1(207)(-)(425).4D/E fusion protein with lysates containing activated p42(mapk/erk2) led to the phosphorylation of Ser and Thr residues in addition to the previously defined sites at T236, S240, S244, and S270.
