Target Species

Human

Target Name

MDC1

Target Full Name

Mediator of DNA damage checkpoint protein 1

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 H2AX. 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.

Target Subcellular Location

Nucleus. Chromosome. Note=Associated with chromatin. Relocalizes to discrete nuclear foci following DNA damage, this requires 'Ser-139' phosphorylation of H2AX. Colocalizes with APTX at sites of DNA double-strand breaks.

Target Tissue Specificity

Highly expressed in testis.

Target Research Area

Epigenetics and Nuclear Signaling

Target Synonyms

Homologue to Drosophila photoreceptor protein calphotin; MDC 1; Mdc1; MDC1_HUMAN; Mediation of DNA damage checkpoint 1; Mediator of DNA damage checkpoint 1; Mediator of DNA damage checkpoint protein 1; NFBD 1; NFBD1; Nuclear factor with BRCT domains 1; Nuclear Factor with BRCT Domains Protein 1

Target Background

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.
