General description

E6AP/UB3A is an interesting E3 ubiquitin protein ligase with newly discovered alternative functions as well. It is the founding member of the HECT (Homologous to E6AP C terminus) family of ubiquitin ligases and recent research is shedding new light on its influence in health and disease. Ubiquitin substrates for E6AP/UB3A ligase include RAD23A/B, MCM7 (items involved in DNA replication), Annexin A1, PML tumor suppressor and the cell cycle regulator CDKN1B. E6AP also catalyzes the high risk human papilloma virus E6 mediated ubiquitination of p53, which contributes to the neoplastic progression of cells infected by these viruses. E6AP has also been identified as a steroid hormone receptor transcriptional coactivator, and E6AP has a role in numerous diseases including cancers and neurological syndromes. Additionally, E6AP/UB3A is developmentally important for adipogenesis, granulocyte maturation and synaptic processes, where it acts as a down-regulator. IE6AP/UBE3A protein is active as a trimer of E6AP subunits and widely expressed.

The role of E6AP in the regulation of p53 protein levels in human papillomavirus (HPV)-positive and HPV-negative cells.
Talis, A L, et al.
The Journal of Biological Chemistry, 273, 6439-6445 (1998)

The E6 protein of the high-risk human papillomaviruses (HPVs) and the cellular ubiquitin-protein ligase E6AP form a complex which causes the ubiquitination and degradation of p53. We show here that HPV16 E6 promotes the ubiquitination and degradation of E6AP itself.
