Phospho-SMC1 (Ser957) Antibody #4801
This product is discontinued
Gallery: Phospho-SMC1 (Ser957) Antibody #4801
Phospho-SMC1 (Ser957) Antibody detects endogenous levels of SMC1 only when phosphorylated at Ser957.Species predicted to react based on 100% sequence homology: Xenopus, Bovine
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser957 of human SMC1. Antibodies are purified by protein A and peptide affinity chromatography.
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). 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 (3). SMC1 phosphorylation is ATM-independent in cells subjected to other forms of DNA damage, including UV light and hydroxyurea treatment (4). While phosphorylation of SMC1 is required for activation of the IR-induced intra-S-phase checkpoint, the precise mechanism is not well understood and may involve a conformational change that affects SMC1-SMC3 interaction (3).
