HUS1 Checkpoint Homolog (S. pombe), Checkpoint Protein HUS1, Hus1+-like protein.
HUS1 is a component of an evolutionarily conserved, genotoxin-activated checkpoint complex. HUS1 protein connects with Rad9 and Rad1 to form the 9-1-1(RAD9-RAD1-HUS1) complex, that confines to DNA lesions and promotes DNA damage signaling and repair or apoptosis, cell cycle arrest. The trimeric complex is structurally similar to the proliferating cell nuclear antigen (PCNA) sliding clamp and interacts with Rad17 as a clamp-clamp loader pair during the DNA damage response.
HUS1 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 300 amino acids (1-280a.a.) and having a molecular mass of 33.8kDa.
HUS1 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Sterile Filtered clear solution.
The HUS1 protein solution (0.25mg/ml) is formulated in 20 mM Tris-HCl Buffer (pH 8.0), 100 mM NaCl and 40% Glycerol.
