The recognition component of this pathway, encoded by this gene, binds to a destabilizing N-terminal residue of a substrate protein and participates in the formation of a substrate-linked multiubiquitin chain. This leads to the eventual degradation of the substrate protein. The protein described in this record has a RING-type zinc finger and a UBR-type zinc finger. Mutations in this gene have been associated with Johanson-Blizzard syndrome. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N-terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation. May be involved in pancreatic homeostasis. Binds leucine and is a negative regulator of the leucine-mTOR signaling pathway, thereby controlling cell growth. {ECO:0000269|PubMed:15548684, ECO:0000269|PubMed:16311597, ECO:0000269|PubMed:20298436, ECO:0000269|PubMed:20835242}. |ClpS| |zf-UBR| |ubiquitin-dependent protein catabolic process via the N-end rule pathway| |leucine binding| |cellular response to leucine| |response to leucine| |negative regulation of TOR signaling| |proteasome complex| |cellular response to amino acid stimulus| |regulation of TOR signaling| |ubiquitin ligase complex| |response to amino acid| |cellular response to acid chemical| |ubiquitin protein ligase activity| |proteasome-mediated ubiquitin-dependent protein catabolic process| |response to acid chemical| |proteasomal protein catabolic process| |negative regulation of intracellular signal transduction| |ubiquitin-dependent protein catabolic process| |modification-dependent protein catabolic process| |modification-dependent macromolecule catabolic process| |proteolysis involved in cellular protein catabolic process| |cellular response to organonitrogen compound| |cellular protein catabolic process| |cellular response to nitrogen compound| |protein catabolic process| |protein ubiquitination| |protein modification by small protein conjugation| |zinc ion binding| |cellular macromolecule catabolic process| |protein modification by small protein conjugation or removal| |response to organonitrogen compound| |macromolecule catabolic process| |cellular response to oxygen-containing compound| |organonitrogen compound catabolic process| |response to nitrogen compound| |cellular response to endogenous stimulus| |negative regulation of signal transduction| |proteolysis| |negative regulation of cell communication| |negative regulation of signaling| |response to endogenous stimulus| |response to oxygen-containing compound| |negative regulation of response to stimulus| |organic substance catabolic process| |cellular catabolic process| |regulation of intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp79|Q15 2.7μM R02 exp79]]|1.72| No correlation found to any other genes in chemogenomics.
