    basic FUNCTION
  • playing an essential role for a wide variety of DNA metabolic processes, including DNA replication, recombination, DNA damage detection and repair
  • participating in DNA damage-response pathways (Li 2009)
  • SOSS complex (NABP1, NABP2, INTS3, INIP) is likely involved in the maintenance of genome stability
  • potential role for NABP2/NABP1 in the protection of newly replicated leading- and lagging-strand telomeres
  • NABP1 and 2 are single-stranded (ss) DNA- and RNA-binding proteins, and function in DNA repair
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • forming a complex with INTS3 and C9orf80 , complex required for efficient homologous recombination (HR)-dependent repair of DNA double strand breaks and ATM-dependent signaling pathways (Li 2009)
  • components of the NABP2/NABP3-INTS3-C9orf80 heterotrimeric protein complex shown to participate in DNA damage response and maintenance of genome stability
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binds single-stranded nucleic acids, but not double-stranded DNA, suggesting that it functions as a single-stranded nucleic acid binding protein
  • single-stranded DNA-binding protein complex, NABP1/NABP2-INTS3 can recruit the checkpoint complex to initiate ATR signaling
  • INTS3, but not C9ORF80, affects the nucleic acid-binding ability of NABP1 and NABP2
  • INTS3 might regulate NABP1/NABP2 biological function
