Monoclonal Mouse Ascites B
Structural maintenance of chromosomes 1 (SMC1) protein is a chromosomal protein member of the cohesin complex that enables sister chromatid cohesion and plays a role in DNA repair (1,2). In response to ionizing radiation (IR), as part of the intra-S-phase DNA damage checkpoint, ATM/NBS1-dependent phosphorylation of SMC1 occurs at Ser957 and Ser966 (3). In cells subjected to other forms of DNA damage, including UV light and hydroxyurea treatment, SMC1 phosphorylation is ATM-independent (4). While phosphorylation of SMC1 is required for activation of the IR-induced intra- S-phase checkpoint, the precise mechanismis not well understood and may involve a conformational change that affects SMC1-SMC3 interaction (3).
