Previous GeneCards Identifiers for UBR1 Gene
The N-end rule pathway is one proteolytic pathway of the ubiquitin system. 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]
GeneCards Summary for UBR1 Gene
UBR1 (Ubiquitin Protein Ligase E3 Component N-Recognin 1) is a Protein Coding gene. Diseases associated with UBR1 include johanson-blizzard syndrome and urethral obstruction. Among its related pathways are Class I MHC mediated antigen processing and presentation and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include ubiquitin-protein transferase activity and leucine binding. An important paralog of this gene is UBR3.
UniProtKB/Swiss-Prot for UBR1 Gene
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.
