  • 常规说明

      

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

靶标

  • 功能

    Cleavable component of the cohesin complex, involved in chromosome cohesion during cell cycle, in DNA repair, and in apoptosis. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At metaphase-anaphase transition, this protein is cleaved by separase/ESPL1 and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis. Also plays a role in apoptosis, via its cleavage by caspase-3/CASP3 or caspase-7/CASP7 during early steps of apoptosis: the C-terminal 64 kDa cleavage product may act as a nuclear signal to initiate cytoplasmic events involved in the apoptotic pathway.
  • 序列相似性

    Belongs to the rad21 family.
  • 结构域

    The C-terminal part associates with the head of SMC1A, while the N-terminal part binds to the head of SMC3.
  • 翻译后修饰

    Cleaved by separase/ESPL1 at the onset of anaphase. Cleaved by caspase-3 and caspase-7 at the beginning of apoptosis. The cleavage by ESPL1 and caspase-3 take place at different sites.
    Phosphorylated; becomes hyperphosphorylated in M phase of cell cycle. The large dissociation of cohesin from chromosome arms during prophase may be partly due to its phosphorylation by PLK.
  • 细胞定位

    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, it is cleaved by separase/ESPL1, leading to the dissociation of the complex from chromosomes, allowing chromosome separation. Once cleaved by caspase-3, the C-terminal 64 kDa cleavage product translocates to the cytoplasm, where it may trigger apoptosis.

Answer

I've compiled some information below regarding potential primer sets for the ChIP antibodies we talked about, where information was lacking (verified in ChIP by other researches), I included links to abReviews and references that used the antibody in ChIP.

1. ab817: GAPDH (+), GAD1 (-), AFM (-), Factor VIII (-)

2. ab1791: GAPDH, RPL30, ALDOA, MYO-D, SERPINA, AFM, SAT2, SATa (each batch is verified against this primer set, an example image of one batch test is given on the datasheet)

3. ab7030: was verified in ChIP by other researchers submitting data through our abReview system and specific references. Their positive and negative controls used are given through the link below, as well as a "click to contact this user" link that allows you to contact the researchers if you would like more specific primer information. The specific references with ChIP listed in bold are good sources for positive and negative primers as well.
