A functional variant in ubiquitin conjugating enzyme e2 l3. E2 ubconjugating enzymes are critical in this cascade, as they regulate both the topology of the polyub chains and the processivity of the polyubiquitination reaction 45,46,47. Ube2v1 ubiquitinconjugating enzyme e2 variant 1 homo. The sequences of qpcr primers are listed in additional file 2. A subset of ubiquitinconjugating enzymes is essential for. However, the association between ube2l3 and children with chb and the underlying mechanism remain unclear. This gene encodes a member of the e2 ubiquitinconjugating enzyme family. Ubiquitinconjugating enzyme e2 variant 2 ube2v2 antibodies. Ube2v2 ubiquitinconjugating enzyme e2 variant 2 homo. Human e2s can be classified into 17 subfamilies based on phylogenetic analyses 22. For example, a complex of ubcubiquitinconjugating enzyme e2n ube2n and mms2ubiquitinconjugating enzyme e2 variant 2 ube2v2 synthesizes lys 63linkage type of ubiquitin polymers moraes et al. To reveal the role of e2 in plant innate immunity, we identified and cloned 40 tomato genes encoding ubiquitin e2 proteins.
Of the three classes of enzymes involved in ubiquitination, ubiquitinconjugating enzymes e2 have been often incorrectly considered to play merely an auxiliary role in the process, and few e2 enzymes have been investigated in plants. They have sequence similarity to other ubiquitinconjugating enzymes but lack the conserved cysteine residue that is critical for the catalytic activity of e2s. Involvement of ubiquitinconjugating enzyme e2 gene. Ubiquitinconjugating enzyme e2, j1, u ube2j1 antibodies. The tomato fni3 lysine63specific ubiquitinconjugating enzyme and suv ubiquitin e2 variant positively regulate plant immunity. The e2 family comprises genes in saccharomyces cerevisiae and at least 38 genes in humans box 2. Ubiquitination involves at least three classes of enzymes. Active e2s possess a core ubiquitinconjugating ubc domain, which contains the catalytic cys residue and interacts with e1s. Ubiquitinconjugating enzyme e2 variant 1 is a protein that in humans is encoded by the ube2v1 gene. Ubiquitinconjugating e2 enzyme variant 1 ube2v1, one member of. Ubiquitinconjugating enzyme e2 variant proteins constitute a distinct subfamily within the e2 protein family.
Ube2v2 gene genecards ub2v2 protein ub2v2 antibody. Ubiquitinconjugating enzyme e2 variant 2 is a protein that in humans is encoded by the ube2v2 gene. The human genome encodes more than 40 e2s 45,46,47, which catalyze attachment of ub to different lysines on protein substrate or ub, during mono or polyubiquitination. While discussing e2 ubiquitinconjugating enzymes and e3 ligases earlier, we mentioned that the particular site of ub chain linkage between ub molecules can be determined by the e2 alone david et al. Ube2v1mediated ubiquitination and degradation of sirt1 promotes.
