Dnmt3b

DNMT3B is an enzyme that plays a key role in modifying DNA, specifically by adding chemical groups called methyl groups to DNA strands. This process, known as DNA methylation, helps regulate gene activity, turning genes on or off as needed. DNMT3B is especially important during early development, ensuring genes are appropriately regulated for normal growth. If DNMT3B doesn't work correctly, it can lead to improper gene regulation, which is linked to developmental disorders and certain cancers. Overall, DNMT3B is vital for maintaining proper gene function and stability within cells.
