JmjC domain

The JmjC domain is a specialized part of certain proteins involved in regulating genes. It functions as an enzyme that removes chemical tags called methyl groups from specific amino acids on histone proteins, which help organize DNA in cells. By doing this, the JmjC domain influences gene activity, turning genes on or off as needed. This process is critical for proper cell function, development, and response to environmental signals. In essence, the JmjC domain helps control how tightly or loosely DNA is packed, thereby regulating gene expression.
