GRR1/YJR090C Summary Help

Standard Name GRR1 1
Systematic Name YJR090C
Alias CAT80 , COT2 2 , SSU2 3 , SDC1 4
Feature Type ORF, Verified
Description F-box protein component of an SCF ubiquitin-ligase complex; modular substrate specificity factor which associates with core SCF (Cdc53p, Skp1p and Hrt1p/Rbx1p) to form the SCF(Grr1) complex; SCF(Grr1) acts as a ubiquitin-protein ligase directing ubiquitination of substrates such as: Gic2p, Mks1p, Mth1p, Cln1p, Cln2p and Cln3p; involved in carbon catabolite repression, glucose-dependent divalent cation transport, glucose transport, morphogenesis, and sulfite detoxification (2, 3, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
