Applications Key: W=Western Blotting
Specificity / Sensitivity
TCEB3/Elongin A Antibody recognizes endogenous levels of total TCEB3/Elongin A protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human TCEB3/Elongin A protein. Antibodies are purified by protein A and peptide affinity chromatography.
The Elongin complex is a heterotrimer composed of TCEB3/Elongin A, Elongin B (TCEB2), and Elongin C (TCEB1) subunits (1-3). The Elongin complex regulates the rate of RNA polymerase II (RNAPII) transcription elongation by releasing the transient pausing of RNAPII at multiple sites along the DNA. TCEB3/Elongin A is the transcriptionally active subunit, while Elongin B and C subunits play a regulatory role (3,4). TCEB3/Elongin A may be required for expression of a subset of cell cycle regulated genes, and embryonic stem (ES) cells lacking TCEB3/Elongin A show abnormalities in cell size, growth, and cell cycle distribution (5). In addition, the Elongin complex has been shown to interact with the cullin family and RING finger proteins Cul5/Rbx2 upon UV-induced DNA damage, removing arrested RNAPII at sites of DNA damage by ubiquitination and degradation as part of an E3 ubiquitin ligase (6).
