靶标

  • 功能

    Plays an important role in homologous strand exchange, a key step in DNA repair through homologous recombination. Binds to single and double-stranded DNA and exhibits DNA-dependent ATPase activity. Catalyzes the recognition of homology and strand exchange between homologous DNA partners to form a joint molecule between a processed DNA break and the repair template. Binds to single-stranded DNA in an ATP-dependent manner to form nucleoprotein filaments which are essential for the homology search and strand exchange (PubMed:26681308). Part of a PALB2-scaffolded HR complex containing BRCA2 and RAD51C and which is thought to play a role in DNA repair by HR. Plays a role in regulating mitochondrial DNA copy number under conditions of oxidative stress in the presence of RAD51C and XRCC3.
  • 组织特异性

    Highly expressed in testis and thymus, followed by small intestine, placenta, colon, pancreas and ovary. Weakly expressed in breast.
  • 疾病相关

    Breast cancer
    Mirror movements 2
    Defects in RAD51 are found in a patient with microcephaly, mental retardation without bone marrow failure and pediatric cancers.
  • 序列相似性

    Belongs to the RecA family. RAD51 subfamily.
    Contains 1 HhH domain.
  • 结构域

    The nuclear localization may reside in the C-terminus (between 259 and 339 AA).
  • 翻译后修饰

    Ubiquitinated by the SCF(FBXO18) E3 ubiquitin ligase complex, regulating RAD51 subcellular location and preventing its association with DNA.
    Phosphorylated. Phosphorylation of Thr-309 by CHEK1 may enhance association with chromatin at sites of DNA damage and promote DNA repair by homologous recombination. Phosphorylation by ABL1 inhibits function.
  • 细胞定位

    Nucleus. Cytoplasm. Cytoplasm, perinuclear region. Mitochondrion matrix. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Colocalizes with RAD51AP1 and RPA2 to multiple nuclear foci upon induction of DNA damage. DNA damage induces an increase in nuclear levels. Together with FIGNL1, redistributed in discrete nuclear DNA damage-induced foci after ionizing radiation (IR) or camptothecin (CPT) treatment. Accumulated at sites of DNA damage in a SPIDR-dependent manner.

    Question

    The customer has responded as below;

    Please could we have a credit note.

    In regards to the ab58101 antibody, I think it is generally accepted that full length Sash1 runs at 170 kDa, however another band can be observed at 130kDa in some samples (see attached paper). However, using ab58101 neither the 170 kDa or 130 kDa band can be detected, whereas the Sash1 antibody from one of your competitors detects both bands in the same sample.

    Thanks for your help and hope to hear from you soon

    Kind regards,

    Question

    Please see below for the response from the customer

    I have attached western images for the SETBP1 and Sash1 antibodies. Unfortunately I didn't save any of the IF images for the Rad51 antibody as the quality was too bad.

    Thanks!

    Answer

    Thank you for your email.

    I would be happy to process refunds for ab213 and ab68715. Could you however let me know why the customer expecting a 170kDa band for ab58101 which should be nearly 130-140 kDa.

    Question

    Please see below for an email we have received from a customer;

    I've ordered several antibodies from AbCam via Sapphire in the last few months and on the whole the quality has been very good. However, we have had three antibodies that have not worked at all for western blot or immunofluorescence and were wondering whether we could get a refund on these three?

    Ab213 Rad51 antibody – this antibody shows a lot of background and cytoplasmic staining on immunofluorescence at the recommended concentration and lower and we are unable to see DNA repair foci following DNA damage induction via IR.

    Sapphire Order #: PO-15316
    Abcam Invoice #: 1348460E

    AB68715 SETBP1 antibody – we are unable to detect a band of the expected size of around 170 kDa on western blot.

    Sapphire Order #: PO-15671

    Abcam Invoice #: 1353502-SAP002E

    AB58101 SASH1 antibody – we were unable to detect a band at the correct size of around 170 kDa via western blot or any staining via IF.

    Sapphire Order #: PO-15316

    Abcam Invoice #: 1347756F

    All of these antibodies have been trialled by at least two experienced people in our lab and western blotting and immunofluorescence are techniques we have extensive experience with. I can provide further details of the protocols used if required.

    Thanks for your help!

    Asked on May 17 2012

    Answer

    Thank you for contacting Abcam.

    I just had a few more protocol questions for you regarding the problems you are having with ab213 in western blot.

    1 - Why was 2 different lysis buffers used in the extraction protocol? Either of them should have been suffcient on their own.

    2 - Whenyou say that the wetern blotting did not work. Does that means there was no signal, high background, weak signal?

    3 - Could you please provide the lot number of the antibody you are using?

    I look forward to your reply and helping resolve this situation.

    Question

    ICC: sees big red blob in nucleus (correct location) MCF7 cells, treatment with mitomicine C Ab:1/500 1h secondary: 1/200 Texas red (goat anti-mouse), works well otherwise pre-extraction with 0.25% TX fixation: 3% PFA perm step: 0.5% TX no separate blocking step, but done with primary incubation in 3% BSA suggestions: use less antibody (secondary, maybe also primary), include separate blocking step, omit pre-extraction step)

    Answer

    Thank you for contacting us. I am sorry to hear that the antibody is giving problems. As we discussed yesterday over the phone, the following suggestions might help to get rid of the red blob you are seeing in the nuclei.: 1) use less antibody (for the secondary: e.g. 1/500 or even 1/1000, maybe also for the primary: e.g. 1/1000) 2) include a separate blocking step (e.g. 3-5% BSA or 10% goat serum) 3) omit the pre-extraction step Please let me know if these if these suggestions are of help or not. If the tips do not help, please let me know your PO or order number. If the product was purchased within the last 6 months, we can discuss a free of charge replacement, credit or refund according to our Abpromise guarantee. I wish you good luck with your experiments and look forward to hear back from you.
