補足情報

MDC1 also known as mediators of DNA damage checkpoint protein 1 or ABF-M 1711 is an important player in the DNA damage response (DDR). It has a mass of approximately 220 kDa. MDC1 is highly expressed in various human tissues particularly where cell turnover is high like in the bone marrow and lymphoid organs. In cellular operations MDC1 serves as a scaffold protein that coordinates recruitment and activation of DDR machinery at sites of double-strand breaks (DSBs) on DNA.
Biological function summary

This protein plays a vital role in maintaining genomic stability by binding to phosphorylated histone H2AX at DSB sites. It is not a solitary player; MDC1 functions as part of a larger protein complex including factors like RNF8 RNF168 and 53BP1. This complex is essential for amplifying the DDR signal and facilitating the repair process through non-homologous end joining (NHEJ) and homologous recombination (HR). MDC1's interaction with other repair proteins helps to extend the signal required for effective DNA repair.

Pathways

MDC1 significantly influences cellular pathways involving DNA damage sensing and repair and cell cycle checkpoints. It ties closely to the ATM kinase pathway which is activated in response to DSBs. MDC1 aids ATM in phosphorylating downstream targets like CHK2 and p53 for cell cycle arrest. It also connects with BRCA1 interacting in HR repair pathways to ensure accurate repair of DSBs. Both ATM and BRCA1 interactions illustrate MDC1's pivotal role in maintaining DNA integrity.

MDC1 expression and functionality have profound implications on cancer and immunodeficiencies. Abnormal MDC1 expression or mutations can lead to impaired DNA repair and genomic instability often associated with tumor progression in cancers such as breast cancer. Moreover MDC1 interacts with proteins like p53 which is a well-known tumor suppressor to hinder cancer development by stopping the cell cycle for repair or triggering apoptosis if the damage is beyond repair. Dysregulation in MDC1-related pathways can also compromise immune system effectiveness further underpinning its significance in disease contexts.

Histone reader protein 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 (PubMed : 12475977, PubMed : 12499369, PubMed : 12551934, PubMed : 12607003, PubMed : 12607004, PubMed : 12607005, PubMed : 12611903, PubMed : 14695167, PubMed : 15201865, PubMed : 15377652, PubMed : 16049003, PubMed : 16377563, PubMed : 30898438). Specifically recognizes and binds histone H2AX phosphorylated at 'Ser-139', a marker of DNA damage, serving as a scaffold for the recruitment of DNA repair and signal transduction proteins to discrete foci of DNA damage sites (PubMed : 12607005, PubMed : 15201865, PubMed : 16049003, PubMed : 16377563, PubMed : 30898438). Also required for downstream events subsequent to the recruitment of these proteins (PubMed : 12607005, PubMed : 15201865, PubMed : 16049003, PubMed : 16377563, PubMed : 18582474). These include phosphorylation and activation of the ATM, CHEK1 and CHEK2 kinases, and stabilization of TP53/p53 and apoptosis (PubMed : 12499369, PubMed : 12551934, PubMed : 12607004). ATM and CHEK2 may also be activated independently by a parallel pathway mediated by TP53BP1 (PubMed : 12499369, PubMed : 12551934, PubMed : 12607004). Required for chromosomal stability during mitosis by promoting recruitment of TOPBP1 to DNA double strand breaks (DSBs) : TOPBP1 forms filamentous assemblies that bridge MDC1 and tether broken chromosomes during mitosis (PubMed : 30898438). Required for the repair of DSBs via homologous recombination by promoting recruitment of NBN component of the MRN complex to DSBs (PubMed : 18411307, PubMed : 18582474, PubMed : 18583988, PubMed : 18678890).
