Target

  • Function
    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.
  • Tissue specificity
    Highly expressed in testis.
  • Sequence similarities
    Contains 2 BRCT domains.
    Contains 1 FHA domain.
  • Domain
    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.
  • Post-translational
    modifications
    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.
  • Cellular localization
    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 [MDC1-50] images

  • ab50003 staining MDC1 in human U2OS cells by Immunocytochemistry/ Immunofluorescence.
    Cells were fixed in formaldehyde, permeabilized using NP40, blocked with 3% BSA for 3 hours at 25°C and then incubated with ab50003 at a 1/200 dilution for 1 hour at 25°C. The secondary used was an Alexa-Fluor 488 conjugated sheep anti-mouse IgG polyclonal used at a 1/500 dilution.

    MDC1 appears as green foci, the nucleus has been stained with DAPI (blue).
