The Claim

The A554V mutation reduces the thermal stability of the RFTS-containing DNMT1 protein by approximately 2°C, decreasing the melting temperature (Tm) from 55.0 ± 0.1°C to 53.2 ± 0.1°C, while the thermal stability of the isolated RFTS domain alone remains unaffected.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Scientists found that a small genetic change called A554V makes a protein involved in DNA copying slightly less stable when heated, dropping its stability by about 2 degrees Celsius - but this doesn't happen when they look at just the part of the protein where the change occurs.

See the scientific wording

The A554V mutation decreases the thermal stability of RFTS-containing DNMT1 by approximately 2°C (Tm decreased from 55.0 ± 0.1°C to 53.2 ± 0.1°C), while the isolated RFTS domain thermal stability remains unchanged

What the research says

1 study

  1. Study: Disease-Associated Mutation A554V Disrupts Normal Autoinhibition of DNMT1

    The study examined the A554V mutation in DNMT1 and found that it reduces the thermal stability of the full protein containing the RFTS domain, while the isolated RFTS domain alone remains unchanged - exactly what the claim describes.
