Background InformationMDC1 is a subunit of the cohesin complex and is an essential protein required for sister chromatid cohesion in mitosis and meiosis. Temperature-sensitive mutations of this protein have been associated with defects in sister chromatid cohesion, chromosome condensation, and chromosome segregation. Its expression is cell cycle regulated and peaks in S phase. Expression of MDC1 is required for the S- and G2/M-checkpoint-mediated cell cycle arrest in response to DNA damage. MDC1 has been shown to interact with H2A.X near sites of DNA double-strand breaks and recruit ATM kinase to the damaged region of DNA. Consistent with this role, MDC1 also appears to modulate the function of other proteins involved in the DNA damage checkpoint such as BRCA1 and Chk2.

Entrez Gene Number
Entrez Gene SummaryThe protein encoded by this gene contains an N-terminal forkhead domain, two BRCA1 C-terminal (BRCT) motifs and a central domain with 7 divergent copies 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. Mice with mutations in this gene exhibit growth retardation, male infertility, immune defects, chromosome instability, DNA repair defects, and radiation sensitivity. [provided by RefSeq]

UniProt Number
UniProt SummaryFUNCTION: 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 By similarity.

SUBUNIT STRUCTURE: Interacts with several proteins involved in the DNA damage response, although not all these interactions may be direct. Interacts with CHEK2/CHK2/CDS1, which requires ATM-mediated phosphorylation 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 G22P1/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. Interacts with CEP164 By similarity. Interacts with H2AFX, which requires phosphorylation of H2AFX. Interacts with the MRN complex, composed of MRE11A/MRE11, RAD50, and NBN.

SUBCELLULAR LOCATION: Nucleus. Note: Associated with chromatin. Relocalizes to discrete nuclear foci following DNA damage, this requires phosphorylation of H2AFX. Ref.1

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 By similarity.

PTM: 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 By similarity.

SEQUENCE SIMILARITIES: Contains 2 BRCT domains.

Contains 1 FHA domain.
Molecular Weight ~ 184 kDa. There are 4 isoforms of human MDC1 because of splicing with molecular weights of approximately 227, 198, 196, and 117 kDa.
