UBI4/YLL039C Summary Help

Standard Name UBI4 1
Systematic Name YLL039C
Alias SCD2 , UB14
Feature Type ORF, Verified
Description Ubiquitin; becomes conjugated to proteins, marking them for selective degradation via the ubiquitin-26S proteasome system; essential for the cellular stress response; encoded as a polyubiquitin precursor comprised of 5 head-to-tail repeats; protein abundance increases in response to DNA replication stress (1, 2, 3, 4, 5, 6, 7)
