UBA domain found in a putative ubiquitin conjugating enzyme from plasmodium Yoelii (pyUCE) and similar proteins
P. Yoelii ubiquitin-conjugating enzyme and other uncharacterized family members show high sequence similarity to the human Huntingtin interacting protein-2 (HIP2) which belongs to a class II E2 ubiquitin-conjugating enzyme family. These proteins may play roles in the ubiquitin-mediated protein degradation pathway. They all contain a C-terminal ubiquitin-associated (UBA) domain in addition to an N-terminal catalytic ubiquitin-conjugating enzyme E2 (UBCc) domain.
Feature 1:putative polypeptide substrate binding site [polypeptide binding site]
Evidence:
Comment:Based on structural evidence that Homo sapiens ubiquitin-conjugating enzyme E2-25 kDa (2O25) forms a complex with Sumo-1- conjugating enzyme Ubc9.
