Ubiquitylation features

Ubiquitylation site  

Ubiquitylation type Not Determined
Features Failure of a dominant negative UbcH7 to inhibit transducin beta-gamma ubiquitylation argues against an essential role for UbcH7 in transducin beta-gamma ubiquitylation, although data do not exclude the possibility that UbcH7 participates with UbcH5 in a combinatorial mechanism

Ubiquitylation/deubiquitylation machinery

E2 UbcH5 and UbcH7
E3 Not determined
E4/AP Not determined
DUB Not determined
Comments The primary recognition determinants for transducin beta-gamma ubiquitylation appear to reside on transducin beta. Transducin beta-gamma association with phosducin blocks transducin beta-gamma ubiquitylation and subsequent degradation. Transducin gamma species containin not more than four ubiquitin moieties, with monoubiquitylated species predominating
