High impact information on SAE2

  • Although the interaction of UBA2 with Lys48-linked diubiquitin involves the same hydrophobic surface on each ubiquitin unit as that utilized in monoubiquitin:UBA complexes, our results show how the "closed" conformation of Lys48-linked diubiquitin is crucial for high-affinity binding [1].
  • Here, we use NMR to unveil the structural basis of selective recognition of Lys48-linked di- and tetraubiquitin chains by the UBA2 domain of hHR23A [1].
  • We report here that the adenoviral protein Gam1 inhibits the SUMO pathway by interfering with the activity of E1 (SAE1/SAE2) [2].
  • The human UBA2 gene is located on chromosome 19q12 [3].
 

Other interactions of SAE2

  • Human AOS1 is homologous to the N-terminal half of E1, whereas human UBA2 is homologous to the C-terminal half of E1 [3].
