A specific part of the DNMT1 protein called the RFTS domain acts like a built-in off switch - it blocks the main part of the protein from attaching to DNA, keeping the enzyme turned off through internal interactions between different parts of the protein.

Disease-Associated Mutation A554V Disrupts Normal Autoinhibition of DNMT1
Cross-Sectional Study
In Vitro
2023 SepThe study shows that the RFTS domain normally acts as a brake on DNMT1 activity by blocking the active site and preventing DNA binding. When researchers introduced a mutation that disrupts this brake mechanism, DNMT1 became hyperactive - proving the claim's description of how RFTS inhibits DNMT1 is correct.
