TCEB1: Proteins and Enzymes

Elongin C (also known as RNA polymerase II transcription factor SIII p15 subunit and transcription elongation factor B polypeptide 1) is a 15 kD member of the SKP1 family. Elongin functions as a regulatory subunit of a general transcription elongation factor that increases RNA polymerase II transcription elongation past template-encoded arresting sites in the nucleus. The Elongin BC complex acts as adaptor to link Elongin A, VHL, WSB1 or SOCS1 with a module of CUL2 or CUL5 and RBX1 to form E3 ubiquitin ligases. The Poly6131 antibody recognizes the human and mouse elongin C protein and has been shown to be useful for Western blotting.
