Summary
TCEB1 is a part of Elongin BC complex, and is a component of a multiprotein SOCS1 complex that attenuates JAK/STAT signalling by binding to JAK2 and inhibiting JAK2 kinase and by interacting with SOCS box, the Elongin BC complex can increase expression of the SOCS1 protein by inhibiting its degradation.
Entrez Gene
Summary This gene encodes the protein elongin C, which 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. Multiple alternatively spliced transcript variants encoding two distinct isoforms have been identified. [provided by RefSeq, Mar 2011]
