Phosphorylation of any of the Ser or Thr seems to be sufficient to transduce signal, however full activation is achieved when five of these residues are phosphorylated. Example: UniProtKB:P36897-1, 34-503, Ser-165/Ser-187/Ser-189/Ser-191, MOD:00046|Thr-185/Thr-186, MOD:00047.

Phosphorylation occurs by the action of active TGF-beta receptor type-2 within the GS-motifs. UniProtKB:P36897-1, 34-503, Ser-165/Ser-187/Ser-189/Ser-191, MOD:00046|Thr-185/Thr-186, MOD:00047.
