Activity summary

DMC1 also known as DNA Meiotic Recombinase 1 is an important protein involved in homologous recombination during meiosis. It plays a mechanical role by facilitating the exchange of genetic material between parental chromosomes. DMC1 is a 37-kilodalton protein and belongs to the recombinase family. The protein is mainly expressed in germ cells of both males and females particularly in those undergoing meiosis where it controls the DNA strand exchange process important for genetic diversity.

Biological function summary

DMC1 ensures accurate and efficient repair of double-strand breaks during meiosis a critical function for chromosome segregation and gamete viability. It works in concert with other proteins like RAD51 to form a nucleoprotein filament on the single-stranded DNA that promotes homologous pairing and strand exchange. This coordinated action is essential for forming synaptonemal complexes which stabilize homologous chromosomes during prophase I of meiosis.

Pathways

DMC1's role is integral to the homologous recombination repair pathway. It interplays specifically with RAD51 and other recombinases to regulate genetic recombination events. The protein contributes to DNA damage response pathways and is critical for the maintenance and integrity of genetic information during cell division.

Associated diseases and disorders

Mutations or regulatory dysfunctions in DMC1 have been associated with infertility particularly in disorders affecting spermatogenesis and oogenesis. The protein’s malfunction can disrupt meiotic progression leading to aneuploidies and miscarriages. Additionally DMC1 mutations may connect to cancer pathways as faulty homologous recombination increases genomic instability often observed in various types of cancers highlighting potential therapeutic interactions with proteins like BRCA1 and BRCA2.
