Introduction
Nucleic acid binding protein 1 is a part of the SOSS complex, a multiprotein complex
which functions downstream of the MRN complex to promote DNA repair and G2/M
checkpoint. In the SOSS complex,
NABP1 acts as a sensor of single-stranded DNA which binds to single-stranded
DNA, in particular
to polypyrimidines. The SOSS complex links with DNA lesions and affects diverse endpoints in the cellular DNA damage response including cell-cycle checkpoint
activation, recombinational repair and maintenance of genomic stability. NABP1 is essential for
efficient homologous recombination-dependent repair of double-strand breaks (DSBs) and
ATM-dependent signaling pathways.
Description
NABP1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 227 amino acids (1-204 a.a) and having a molecular mass of 24.8kDa.
NABP1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered clear solution.
Formulation
NABP1 protein solution (0.5mg/ml) containing 20mM
Tris-HCl buffer (pH 8.0) 0.2M, NaCl, 50% glycerol and 2mM DTT.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
