靶标

  • 功能
    Required for checkpoint mediated cell cycle arrest in response to DNA damage within both the S phase and G2/M phases of the cell cycle. May serve as a scaffold for the recruitment of DNA repair and signal transduction proteins to discrete foci of DNA damage marked by 'Ser-139' phosphorylation of histone H2AFX. Also required for downstream events subsequent to the recruitment of these proteins. These include phosphorylation and activation of the ATM, CHEK1/CHK1 and CHEK2/CHK2/CDS1 kinases, and stabilization of TP53 and apoptosis. ATM and CHEK2 may also be activated independently by a parallel pathway mediated by TP53BP1.
  • 组织特异性
    Highly expressed in testis.
  • 序列相似性
    Contains 2 BRCT domains.
    Contains 1 FHA domain.
  • 结构域
    Tandemly repeated BRCT domains are characteristic of proteins involved in DNA damage signaling. In MDC1, these repeats are required for localization to chromatin which flanks sites of DNA damage marked by 'Ser-139' phosphorylation of H2AFX.
  • 翻译后修饰
    Phosphorylated upon exposure to ionizing radiation (IR), ultraviolet radiation (UV), and hydroxyurea (HU). Phosphorylation in response to IR requires ATM, NBN, and possibly CHEK2. Also phosphorylated during the G2/M phase of the cell cycle and during activation of the mitotic spindle checkpoint.
  • 细胞定位
    Nucleus. Associated with chromatin. Relocalizes to discrete nuclear foci following DNA damage, this requires 'Ser-139' phosphorylation of H2AFX. Colocalizes with APTX at sites of DNA double-strand breaks.

Anti-MDC1 antibody 图像

  • ab11169 staining MDC1 in HCT116 cells treated with GANT 61 (ab120904), by ICC/IF. Increase in MDC1 expression correlates with increased concentration of GANT 61, as described in literature.
    The cells were incubated at 37°C for 4 hours in media containing different concentrations of ab120904 (GANT 61) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab11169 (1/200 dilution) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

  • ab11169 staining MDC1 in human cervical cancer cells (HeLa) by ICC/IF (immunocytochemistry/immunofluorescence - left image). Cells were paraformaldehyde fixed, permeabilized with Triton X-100 and blocked with 5% BSA for 1 hour at 25°C. The primary antibody (1/200) was incubated with the sample for 12 hours at 4°C. An Alexa Fluor 594®-conjugated Chicken anti-rabbit polyclonal (1/2000) was used as the secondary. The nuclei were stained with DAPI (right image).
