Recombinant Human Ubiquitin-like modifier-activating enzyme 1 (UBA1), partial

1. Polyubiquitination and proteasomal degradation of ezrin and CUGBP1 require Uba6, but not Uba1, and that Uba6 is involved in the control of ezrin localization and epithelial morphogenesis. These data suggest that distinctive substrate pools exist for Uba1 and Uba6 that reflect non-redundant biological roles for Uba6. PMID: 28134249
2. Results from a study on gene expression variability markers in early-stage human embryos shows that UBA1 is a putative expression variability marker for the 3-day, 8-cell embryo stage. PMID: 26288249
3. recent findings put UBA1 at the center of cellular homeostasis and neurodegeneration [review] PMID: 26432019
4. A ubiquitin shuttle DC-UbP reconciles protein ubiquitination and deubiquitination via linking UbE1 and USP5 enzymes. PMID: 25207809
5. Conjugation of the ubiquitin activating enzyme UBE1 with the ubiquitin-like modifier FAT10 targets it for proteasomal degradation PMID: 25768649
6. Ubiquitin-activating enzyme is necessary for 17beta-estradiol-induced breast cancer cell proliferation and migration. PMID: 25138535
7. We expressed and purified the N-terminal domains of human E1 and determined their crystal structures, which contain inactive adenylation domain (IAD) and the first catalytic cysteine half-domain (FCCH) PMID: 25209502
8. Diminished ubiquitylation phenotype observed in enteropathogenic Escherichia coli infected cells corresponds to a strong reduction in the abundance of both Ube1 and Uba6. PMID: 22999844
9. Decrease in free ubiquitin levels under stress allows NEDD8 to be conjugated through Ube1. PMID: 22370482
10. UBA1 knockdown impairs formation of ubiquitin conjugates at DNA double-strand breaks. PMID: 22456334
11. Data show that largazole and ester/keto analogs inhibit ubiquitin E1 activation. PMID: 22279528
12. In conclusion, nUBE1L is a novel human E1 like gene highly expressed in adult testis, which plays key role in ubiquitin system, and accordingly influences spermatogenesis and male fertility. PMID: 15202508
13. analysis of ATP.Mg2+ binding in the catalytic cycle of ubiquitin-activating enzyme PMID: 16595681
14. unusual type of regulation at the level of the E1 enzyme is likely to affect numerous cellular processes and may represent a strategy to coordinate multiple phenotypic changes upon differentiation by using E1 as a "master switch." PMID: 17060614
15. Human Uba6 and Ube1 have distinct preferences for E2 charging in vitro, and their specificity depends in part on their C-terminal ubiquitin-fold domains, which recruit E2s PMID: 17597759
16. Large-scale mutation analysis in genes resulted in detection of 3 rare novel variants in exon 15 of UBE1 that segregate with X-linked infantile spinal muscular atrophy. PMID: 18179898
17. high-level expression of UBE1 was seen inextranodal NK/T cell lymphoma, nasal type; there was no significant difference between UBE1 expression and patients' outcome PMID: 18661401
