Summaries for MDC1 Gene

Entrez Gene Summary for MDC1 Gene

  • The protein encoded by this gene contains an N-terminal forkhead domain, two BRCA1 C-terminal (BRCT) motifs and a central domain with 13 repetitions of an approximately 41-amino acid sequence. The encoded protein is required to activate the intra-S phase and G2/M phase cell cycle checkpoints in response to DNA damage. This nuclear protein interacts with phosphorylated histone H2AX near sites of DNA double-strand breaks through its BRCT motifs, and facilitates recruitment of the ATM kinase and meiotic recombination 11 protein complex to DNA damage foci. [provided by RefSeq, Jul 2008]

GeneCards Summary for MDC1 Gene

MDC1 (Mediator Of DNA-Damage Checkpoint 1) is a Protein Coding gene. Among its related pathways are Homologous Recombination Repair and Homologous Recombination Repair. GO annotations related to this gene include protein C-terminus binding and FHA domain binding. An important paralog of this gene is PAXIP1.

UniProtKB/Swiss-Prot for MDC1 Gene

  • 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 and CHEK2 kinases, and stabilization of TP53 and apoptosis. ATM and CHEK2 may also be activated independently by a parallel pathway mediated by TP53BP1.

    Size:
    2089 amino acids
    Molecular mass:
    226666 Da
    Quaternary structure:
    • Homodimer. Interacts with several proteins involved in the DNA damage response, although not all these interactions may be direct. Interacts with H2AFX, which requires phosphorylation of H2AFX on Ser-139. Interacts with the MRN complex, composed of MRE11A/MRE11, RAD50, and NBN. Interacts with CHEK2, which requires ATM-mediated phosphorylation of Thr-68 within the FHA domain of CHEK2. Interacts constitutively with the BRCA1-BARD1 complex, SMC1A and TP53BP1. Interacts with ATM and FANCD2, and these interactions are reduced upon DNA damage. Also interacts with the PRKDC complex, composed of XRCC6/KU70, XRCC5/KU80 and PRKDC/XRCC7. This interaction may be required for PRKDC autophosphorylation, which is essential for DNA double strand break (DSB) repair. When phosphorylated by ATM, interacts with RNF8 (via FHA domain). Interacts with CEP164. When phosphorylated, interacts with APTX (via FHA-like domain).

Post-translational modifications for MDC1 Gene

  • 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. Phosphorylation at Thr-4 by ATM stabilizes and enhances homodimerization via the FHA domain.
  • Sumoylation at Lys-1840 by PIAS4 following DNA damage promotes ubiquitin-mediated degradation.
  • Ubiquitinated by RNF4, leading to proteasomal degradation; undergoes Lys-48-linked polyubiquitination.
  • Ubiquitination at Lys45
  • Modification sites at PhosphoSitePlus
