HRT1/YOL133W Summary Help

Standard Name HRT1 1
Systematic Name YOL133W
Alias RBX1 , ROC1 2 , HRT2
Feature Type ORF, Verified
Description RING-H2 domain core subunit of multiple ubiquitin ligase complexes; subunit of Skp1-Cullin-F-box (SCF) that tethers the Cdc34p (E2) and Cdc53p (cullin) SCF subunits, and is required for degradation of Gic2p, Far1p, Sic1p and Cln2p; subunit of the Rtt101p-Mms1p-Mms22p ubiquitin ligase that stabilizes replication forks after DNA lesions; subunit of the Cul3p-Elc1p-Ela1p ubiquitin ligase involved in Rpb1p degradation as part of transcription-coupled repair (1, 2, 3, 4, 5, 6, 7, 8)
Name Description High level expression Reduces Ty3 transposition 1
