产品介绍 TCEB2 (Elongin B), 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. Two alternatively spliced transcript variants encoding different isoforms have been described.

Subunit : Heterotrimer of an A (A1, A2 or A3), B and C subunit. Part of E3 ubiquitin ligase complexes with CUL5 or CUL2, RBX1 and a substrate adapter protein that can be either SOCS1, SOCS5, TCEB3, VHL or WSB1 (By similarity). Substrate adapter protein can be a viral protein such as Vif. Interacts with VHL. Found in a complex composed of LIMD1, VHL, EGLN1/PHD2, TCEB2 AND CUL2.

Similarity : Contains 1 ubiquitin-like domain.
