MMS21 also known as NSE2 is a SUMO E3 ligase enzyme involved in sumoylation a post-translational modification process. It weighs approximately 54 kDa and plays an integral role in maintaining genome stability. MMS21 functions by transferring the SUMO protein to various substrate proteins which can alter their activity stability or localization. This protein is expressed in the nucleus where it interacts with other nuclear proteins to aid DNA repair and chromosome segregation.
Biological function summary
MMS21 participates in the structural maintenance of chromosomes (SMC) complex specifically the SMC5/6 complex. This complex is vital for DNA repair replication and maintaining the stability of the genome. MMS21 modulates the sumoylation status of other proteins in these processes thereby influencing cell cycle progression and genomic integrity. Disruption in MMS21 activity can lead to defective chromosome maintenance highlighting its importance in cellular processes.
Pathways
MMS21 plays a significant role in the DNA damage response and homologous recombination repair pathways. In the DNA damage response pathway MMS21 stabilizes replication forks and mediates the repair of DNA double-strand breaks. It interacts with proteins such as RAD51 an essential protein for homologous recombination facilitating the repair of DNA. In these pathways MMS21 ensures the accuracy and effectiveness of DNA repair mechanisms preventing genomic instability.
MMS21 is associated with cancer and genetic syndromes such as Fanconi anemia. The function of MMS21 in repairing DNA and maintaining genome integrity makes its dysregulation a factor in cancer development. Mutations or deficiencies in MMS21 can lead to faulty DNA repair mechanisms like those seen in Fanconi anemia a condition linked to bone marrow failure and cancer susceptibility. MMS21's interaction with other DNA repair proteins including RAD51 highlights its role in safeguarding against genomic instability seen in these diseases.
