Protein
Ankyrin repeat domain-containing protein M-T5
Organism
Myxoma virus (strain Lausanne)
Function
Substrate-specific adapter of SKP1-containing E3 ubiquitin-protein ligases which mediate the ubiquitination and subsequent proteasomal degradation of host target proteins including CDKN1B. Disappearance of host CDKN1B correlates with cell cycle progression through the G0/G1 checkpoint. Therefore, viruses in infected cells are protected from diverse innate host antiviral responses normally triggered by G0/G1 cell cycle arrest.
