NSC15520 is a small molecular inhibitor of Replication Protein A (RPA). NSC15520 specifically recognizes the RPA N-terminal DNA binding domain (DBD), and blocks the interaction of RPA with p53 or RAD9. NSC15520 also inhibtis helix destabilization of a duplex DNA (dsDNA) oligonucleotide, involves in DNA replication, DNA repair, DNA recombination, and DNA damage response signaling.

Description

NSC15520 is a small molecular inhibitor of Replication Protein A (RPA). NSC15520 specifically recognizes the RPA N-terminal DNA binding domain (DBD), and blocks the interaction of RPA with p53 or RAD9. NSC15520 also inhibtis helix destabilization of a duplex DNA (dsDNA) oligonucleotide, involves in DNA replication, DNA repair, DNA recombination, and DNA damage response signaling[1].

In Vitro

NSC15520 (10-.5-10-3.5 M) inhibits the interaction of RPA with GST-p53 peptide with an IC50 value of 10 μM[1].
NSC15520 (0-400 μM; 5 min) inhibits helix destabilization activity[1].
NSC15520 (0-400 μM; 5 min) inhibits RPA binding of a dsDNA 30-mer[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
