| Immunogen | A synthesized peptide derived from human Phospho-SMC1 (S957) 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 . ATM/NBS1-dependent phosphorylation of SMC1 occurs at Ser957 and Ser966 in response to ionizing radiation (IR) as part of the intra-S-phase DNA damage checkpoint. SMC1 phosphorylation is ATM-independent in cells subjected to other forms of DNA damage, including UV light and hydroxyurea treatment. |

Product Overview
Clone FCI-19 is a rabbit monoclonal antibody that recognizes structural maintenance of chromosomes protein 1A (gene SMC1A) phosphorylated at Ser957 in human samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 143.2 kDa, and the supplier reports an observed band at about 160 kDa.
SMC1A is a core subunit of cohesin, a ring-shaped complex that holds sister chromatids together from DNA replication until anaphase. Cohesin also helps shape chromatin loops and supports DNA repair, and SMC1A is phosphorylated by ATM after DNA damage. Mutations cause a form of Cornelia de Lange syndrome.

Immunogen
Synthetic phosphopeptide around Ser957 of human SMC1 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 . ATM/NBS1-dependent rylation of SMC1 occurs at Ser957 and Ser966 in response to ionizing radiation (IR) as part of the intra-S-phase DNA damage checkpoint.
Reactivity Notes
The supplier lists reactivity with human. UniProt places structural maintenance of chromosomes protein 1A in the nucleus and chromosome. The samples tested by the supplier (listed above) are a practical starting point for positive controls. Because the antibody is phospho-specific, signal depends on the phosphorylation state of the sample; a phosphatase-treated lysate is a useful negative control.
