DSK2/YMR276W Summary Help

Standard Name DSK2 1
Systematic Name YMR276W
Feature Type ORF, Verified
Description Nuclear-enriched ubiquitin-like polyubiquitin-binding protein; required for spindle pole body (SPB) duplication and for transit through the G2/M phase of the cell cycle; involved in proteolysis; interacts with the proteasome; protein abundance increases in response to DNA replication stress (2, 3, 4, 5, 6, 7, 8)
