To extend elongation into the transcription unit, a kinase complex called P-TEFb is required. P-TEFb contains the CDK9 kinase, which is a member of the kinase family that controls the cell cycle. P-TEFb acts on the CTD to phosphorylate it further on serine 2 of the heptapeptide repeat.

The α chains of the FcεRI, members of the immunoglobulin superfamily, directly bind the IgE heavy chains, whereas the β and γ chains are responsible for signal transduction.
