TAR DNA binding protein

Normal function

ال TARDBP gene provides instructions for making a protein called transactive response DNA binding protein 43 kDa (TDP-43). This protein is found within the cell nucleus in most tissues and is involved in many of the steps of protein production. The TDP-43 protein attaches (binds) to DNA and regulates an activity called transcription, which is the first step in the production of proteins from genes. This protein can also bind to RNA, a chemical cousin of DNA, to ensure the RNA's stability. The TDP-43 protein is involved in processing molecules called messenger RNA (mRNA), which serve as the genetic blueprints for making proteins. By cutting and rearranging mRNA molecules in different ways, the TDP-43 protein controls the production of different versions of certain proteins. This process is known as alternative splicing. The TDP-43 protein can influence various functions of a cell by regulating protein production.

ال TARDBP gene is particularly active (expressed) during early development before birth when new tissues are forming. Many of the proteins whose production is influenced by the TDP-43 protein are involved in nervous system and organ development.
