    basic FUNCTION
  • transcriptionally active subunit of the elongin complex
  • increasing the average rate of RNA chain elongation across DNA templates
  • ELOA also acts as a component of a cullin-RING ligase that can target stalled pol II for ubiquitylation and proteasome-dependent degradation
  • role for ELOA in the regulation of stress response genes
  • performs dual functions in cells as a component of RNA polymerase II (Pol II) transcription elongation factor Elongin and as the substrate recognition subunit of a Cullin-RING E3 ubiquitin ligase
  • in unstressed cells, ELOA is predominately present as part of Pol II elongation factor Elongin
  • ELOA ubiquitin ligase and the ERCC6 protein function together in a common pathway in response to Pol II stalling and DNA damage
  • CELLULAR PROCESS nucleotide, transcription, elongation

    ANIMAL & CELL MODELS
  • Eloa-deficient embryos exhibit abnormalities in the formation of both cranial and spinal nerves and ELOA(-/-) embryonic stem cells (ESCs) show a markedly decreased capacity to differentiate into neurons
