FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the protein elongin A, 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. [provided by RefSeq, Jul 2008]
PHENOTYPE: Embryos homozygous for a knock-out allele are severely growth retarded, exhibit a wide range of developmental anomalies and die between E10.5 and E12.5, most likely due to massive apoptosis while mutant MEFs show increased apoptosis and senescence-like growth defects.
