MyBioSource.com's TCEB1 Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: ELISA, and Western Blot. The TCEB1 Antibody was generated using eloC, and elongin C as the antigen and it reacts with Human, Mouse, and Rat.
Description
Function: SIII, also known as elongin, is a general transcription elongation factor that increases the RNA polymerase II transcription elongation past template-encoded arresting sites. Subunit A is transcriptionally active and its transcription activity is strongly enhanced by binding to the dimeric complex of the SIII regulatory subunits B and C (elongin BC complex) (PubMed:7821821). In embryonic stem cells, the elongin BC complex is recruited by EPOP to Polycomb group (PcG) target genes in order generate genomic region that display both active and repressive chromatin properties, an important feature of pluripotent stem cells (By similarity).
Subunit Structure: Heterotrimer of an A (ELOA, ELOA2 or ELOA3), ELOB and ELOC subunit (PubMed:17997974). The elongin BC complex interacts with EPOP; leading to recruit the elongin BC complex to Polycomb group (PcG) target genes, thereby restricting excessive activity of the PRC2/EED-EZH2 complex (By similarity). Part of E3 ubiquitin ligase complexes with CUL5 or CUL2, RBX1 and a substrate adapter protein that can be either SOCS1, SOCS5, ELOA, VHL or WSB1 (PubMed:15590694). The elongin BC complex is part of a complex with hydroxylated HIF1A (PubMed:12050673, PubMed:12004076). Interacts with VHL (PubMed:10205047, PubMed:12050673). Interacts with TMF1 (PubMed:15467733). Interacts with SPSB1 (PubMed:17189197). posed of LIMD1, VHL, EGLN1/PHD2, ELOB and CUL2 (PubMed:11006129, PubMed:10205047, PubMed:12050673). Interacts with SPSB1. Interacts with KLHDC10; which may be an E3 ubiquitin ligase complex substrate recognition component (PubMed:23102700).
Similarity: Belongs to the SKP1 family
