  • Function
    Central component of cohesin, a complex required for chromosome cohesion during the cell cycle. The cohesin complex may form a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. Cohesion is coupled to DNA replication and is involved in DNA repair. The cohesin complex plays also an important role in spindle pole assembly during mitosis and in chromosomes movement.
  • Involvement in disease
    Defects in SMC3 are the cause of Cornelia de Lange syndrome type 3 (CDLS3) [MIM:610759]. CDLS is a dominantly inherited multisystem developmental disorder characterized by growth and cognitive retardation, abnormalities of the upper limbs, gastroesophageal dysfunction, cardiac, ophthalmologic and genitourinary anomalies, hirsutism, and characteristic facial features. CDSL3 is a mild form with absence of major structural anomalies typically associated with CDLS. The phenotype in some instances approaches that of apparently non-syndromic mental retardation.
  • Sequence similarities
    Belongs to the SMC family. SMC3 subfamily.
  • Domain
    The flexible hinge domain, which separates the large intramolecular coiled coil regions, allows the heterotypic interaction with the corresponding domain of SMC1A or SMC1B, forming a V-shaped heterodimer. The two heads of the heterodimer are then connected by different ends of the cleavable RAD21 protein, forming a ring structure.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
    Acetylation at Lys-105 and Lys-106 by ESCO1 is important for genome stability and S phase sister chromatid cohesion. Regulated by DSCC1, it is required for processive DNA synthesis, coupling sister chromatid cohesion establishment during S phase to DNA replication.
  • Cellular localization
    Nucleus. Chromosome. Chromosome > centromere. Associates with chromatin. Before prophase it is scattered along chromosome arms. During prophase, most of cohesin complexes dissociate from chromatin probably because of phosphorylation by PLK, except at centromeres, where cohesin complexes remain. At anaphase, the RAD21 subunit of the cohesin complex is cleaved, leading to the dissociation of the complex from chromosomes, allowing chromosome separation.

  • Interphase HeLa (Human epithelial cell line from cervix adenocarcinoma) cells stained with ab9263 (1/500).

    The antibody gave predominantly nuclear staining in all interphase cells investigated.

    ab9263 staining is shown in green. The cells were counterstained with DAPI (red).


  • SMC3 signals (green) in a human spermatocyte at the zygotene-pachytene transition stage.

    Wider signals correspond to synapsed areas, whereas narrower signals show non-synapsed regions.

  • ab9263 Immunoprecipitate in HeLa (Human epithelial cell line from cervix adenocarcinoma) cytosolic and nuclear extracts.

    500 µg of cell lysate incubated with primary antibody (1/100) and matrix (Protein A) in 20mM HEPES ph 7.8, 100 mM KAc for 4 hours at 4°C.

    For Western blotting ab9263 was used at a dilution at 1/1000.

  • ab9263 (4µg/ml) staining SMC3 in human colon using an automated system (DAKO Autostainer Plus). Using this protocol there is strong nuclear staining.
    Sections were rehydrated and antigen retrieved with the 3-in-1 AR buffer citrate pH 6.0. Slides were blocked with peroxidase in 3% H2O2 in methanol for 10 minutes. They were then blocked with a protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with an amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with hematoxylin and coverslipped under DePeX.

    Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
