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 sequence. Among its related pathways are Immune System and SMAD Signaling Network. GO annotations related to this gene include ligase 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.
