annotation rule: PRU01221

General rule information [?]

Accession PRU01221
Dates 27-SEP-2018 (Created)
27-SEP-2018 (Last updated, Version 1)
Data class Domain
Predictors PROSITE; PS51873; TRIAD
Name TRIAD supradomain
Function The cysteine and histidine rich TRIAD domain architecture is highly conserved and found only in eukaryotes. The three fingers that define the TRIAD supradomain always appear in the same order RING1-IBR-RING2. All characterized proteins containing the TRIAD supradomain have been found to possess E3 ligase activity.
