Introduction
TCEB2 is a subunit of the SIIII complex which is a heterotrimer consisting of a transcriptionally active subunit (A) and two regulatory subunits (B and C). TCEB2 initiates elongation by RNA polymerase II by suppressing transient pausing of the polymerase at many sites within transcription units. The von Hippel-Lindau tumor suppressor protein binds to elongins B and C, and thereby inhibits transcription elongation.
Description
TCEB2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 118 amino acids (1-118) and having a molecular mass of 13.1 kDa. TCEB2 is purified by standard chromatography techniques.
Source
Escherichia Coli.
