UniProtKB accession:  P38263

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Substrate-recognition component of the GID complex, a multisubunit ubiquitin ligase that targets enzymes involved in gluconeogenesis for proteasomal degradation when cells are shifted to glucose-containing medium (PubMed:12686616, PubMed:18508925, PubMed:28126757). Specific for substrates with an N-terminal Pro (Pro/N-degron), including FBP1, ICL1 and MDH2 (PubMed:28126757). Has high affinity for the N-terminal sequence Pro-Thr-Leu-Val, and can bind peptides with an N-terminal sequence of the type Pro-[Gly,Ala,Ser,Thr,Asp,Asn,Tyr,His]-[Ala,Val,Leu,Ile,Lys,Arg]-[Val,Cys,Pro,Leu,Ile,Trp] (PubMed:28126757). Required for vacuolar degradation of FBP1 when cells are shifted to glucose-containing medium, probably by targeting FBP1-containing vesicles to the vacuole, but is not required for FBP1 sequestration in cytoplasmic vesicles (PubMed:9508768).
