Structural maintenance of chromosome proteins (SMC) are evolutionarily conserved chromosomal proteins that are components of the cohesin complex, necessary for sister chromatid cohesion. These proteins may also function in DNA repair. It has been reported that SMC1 is a component of the DNA damage response network that functions as an effector in the ATM/NBS1-dependent S-phase checkpoint pathway. SMC1 associates with BRCA1 and is phosphorylated in response to IR in an ATM- and NBS1-dependent manner (1). ATM phosphorylates Smc1 on serines 957 and 966 in vitro and in vivo, and expression of an SMC1 protein mutated at these phosphorylation sites abrogates the ionizing irradiation-induced S phase cell cycle checkpoint. Optimal phosphorylation of these sites in SMC1 after ionizing irradiation also requires the presence of the ATM substrates Nbs1 and Brca1 (2). Applications: Suitable for use in Western Blot, Immunohistochemistry, Immunocytochemistry. Other applications not tested. Recommended Dilution: Western Blot: 1:500-1000 Immunohistochemistry: 1:100-250 Immunocytochemistry: 1:100-250 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. Manufactured incorporating RabMAb(R) technology under Epitomics US patents, No 5,675,063 and 7,429,487, owned by Abcam.
