U1A protein

U1A protein is a specialized molecule found in human cells that helps regulate the process of making proteins from DNA. It specifically binds to a component of the cell's machinery involved in splicing, which is the editing of RNA messages before they are used to produce proteins. By controlling this step, U1A influences how certain genes are expressed, acting as a crucial regulator to ensure the right amount of proteins are made at the right time. Its function is fundamental for normal cell operation and gene regulation.
