Background

NBS1 (Nijmegen breakage syndrome 1, NBN or p95) is a component of the MRE11/RAD50/NBN (MRN complex), which plays a critical role in the cellular response to DNA damage and the maintenance of chromosome integrity. The complex is involved in double-strand break (DSB) repair, DNA recombination, maintenance of telomere integrity, cell cycle checkpoint control and meiosis. The complex possesses single-strand endonuclease activity and double-strand-specific 3′-5′ exonuclease activity, which are provided by MRE11A. NBN modulate the DNA damage signal sensing by recruiting PI3-kinase/PI4-kinase family members ATM, ATR, and probably DNA-PKcs to the DNA damage sites and activating their functions. NBS1 (NBN) also functions in telomere length maintenance by generating the 3′ overhang which serves as a primer for telomerase dependent telomere elongation. NBS1 (NBN) is a major player in the control of intra-S-phase checkpoint and there is some evidence that NBS1 (NBN) is involved in G1 and G2 checkpoints. The roles of NBS1 (NBN)/MRN encompass DNA damage sensor, signal transducer, and effector, which enable cells to maintain DNA integrity and genomic stability.

Positive Control

Active Motif's HeLa nuclear extract (Catalog No. 36010) can be used as a positive control for NBS1 antibody.
