PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • N-terminal region indirectly associated with gamma-tubulin through binding with gamma-tubulin complex protein 2 (TUBGCP2) and/or TUBGCP3
  • five HAT repeats, and intact HAT domain is essential for efficient pre-rRNA processing and cell growth

    text
  • localizes to the centrosome from S-phase to mitosis and to the nucleolus throughout interphase
  • basic FUNCTION
  • involved in RNA processing
  • UTP6 and kendrin (PCNT) provide sites for microtubule nucleation in the mammalian centrosome by anchoring TUBG1
  • able to potentiate APAF1, but not receptor-mediated apoptosis, by increasing downstream caspase activity following cytochrome c release from the mitochondria
  • novel regulator of gamma-tubulin function that plays a role in stabilizing components of the gamma-tubulin small complex, which is in turn essential for assembling the larger gamma-tubulin ring complex

    small molecule
    protein
  • able to modulate selectively APAF1-dependent apoptosis through its direct association with the CED4 domain of APAF1
  • UTP6-WDR36 interaction (HAT domain binds a specific peptide ligand in WDR36)
  • interacting with APAF1 (APAF1 acts by regulating the recruitment of UTP6, with which it interacts, to the centrosome)
