TCEB1 is known as protein elongin C, which is a subunit of the transcription factor B (SIII) complex. The SIII complex is composed of elongins A/A2, B and C. It activates elongation by RNA polymerase II by suppressing transient pausing of the polymerase at many sites within transcription units. Elongin A functions as the transcriptionally active component of the SIII complex, whereas elongins B and C are regulatory subunits. Elongin A2 is specifically expressed in the testis, and capable of forming a stable complex with elongins B and C. The von Hippel-Lindau tumor suppressor protein binds to elongins B and C, and thereby inhibits transcription elongation. Western blots using two different antibodies (P100962-T200 and P100963_P050 / P100963_P100) against two unique regions of this protein target confirm the same apparent molecular weight in our tests.1) Yu, X., et al., (2003) Science 302 (5647), 1056-1060.
