    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus
    text
  • localized throughout the cell nucleus and is not stably associated with ribosomal subunits within the cell nucleus
  • basic FUNCTION
  • methyltransferase activity
  • enhances cancer cell survival in the vasculature by suppressing PLAGL1/TP53-dependent apoptosis, thereby enhancing metastasis
  • is a ribosome biogenesis factor involved in the biosynthesis of 40S ribosomal particles in mammalian cells
  • key role of BUD23 in 40S subunit biogenesis is likely independent of its function as an RNA methyltransferase (PMIID: 25525153)
  • 18S rRNA methyltransferase involved in pre-rRNA processing and ribosome 40S subunit biogenesis
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • last complex formed between TRMT112 and BUD23 proteins modifies 18S rRNA and participates in the 40S biogenesis pathway
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • BUD23 is a novel regulator of chromatin structure affecting NR3C1 recruitment and function, contributing to loss of NR3C1 sensitivity in inflammation, with suppressed expression in pulmonary disease
  • TRMT112 is the interaction partner of BUD23, and stability of BUD23 is regulated through the interaction with TRMT112
  • TRMT112, a small protein (COG2835) conserved in all three domains of life, interacts and activates four methyltransferases (BUD23,N6AMT1) that target different components of the translation machinery (rRNA, tRNAs, release factors)
