👉 Notsystermes are a type of protein that is found in the nucleus, where it plays an important role in regulating gene expression and DNA replication. These proteins can be divided into two main types: the transcription factor (TF) domain-containing proteins (TfDs) and the regulatory subunit (Rds). Tfds bind to specific DNA sequences, allowing them to regulate gene expression by interacting with regulatory elements such as enhancers or沉默子。
