靶标

  • 功能
    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.
  • 组织特异性
    Broadly expressed, with highest levels in skeletal muscle, kidney and pancreas. Present in acinar cells of the pancreas (at protein level).
  • 通路
    Protein modification; protein ubiquitination.
  • 疾病相关
    Defects in UBR1 are a cause of Johanson-Blizzard syndrome (JBS) [MIM:243800]. This disorder includes congenital exocrine pancreatic insufficiency, multiple malformations such as nasal wing aplasia, and frequent mental retardation. Pancreas of individuals with JBS do not express UBR1 and show intrauterine-onset destructive pancreatitis.
  • 序列相似性
    Belongs to the UBR1 family.
    Contains 1 RING-type zinc finger.
    Contains 1 UBR-type zinc finger.
  • 发展阶段
    Expressed in fetal pancreas.
  • 结构域
    The RING-H2 zinc finger is an atypical RING finger with a His ligand in place of the fourth Cys of the classical motif.
  • 翻译后修饰
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • 细胞定位
    Cytoplasm > cytosol.
