The binding of insulin is communicated through the single TM helix of each beta subunit to the paired Tyr kinase domains inside the cell, activating them to phosphorylate each other on three Tyr residues (Tyr1158, Tyr1162, Tyr1163)

TFIIH is the only general transcription factor that has multiple independent enzymatic activities. Its several activities include an ATPase, helicases of both polarities, and a kinase activity that can phosphorylate the CTD tail of RNA polymerase II (on serine 5 of the heptapeptide repeat). TFIIH is an exceptional factor that may also play a role in elongation.

In staphylococcal food poisoning and toxic shock syndrome, exotoxins produced by the pathogens function as superantigens, which can activate all T cells.
