Nuclear proteins
Nuclear proteins are molecules that reside in the nucleus of a cell, the control center that houses genetic material (DNA). These proteins perform essential functions such as organizing and condensing DNA, regulating gene expression by turning genes on or off, and assisting in the process of copying DNA during cell division. They include structural components like nuclear envelope proteins, enzymes involved in modifying DNA and RNA, and transcription factors that influence which genes are active. Overall, nuclear proteins are vital for maintaining the cell’s genetic integrity and controlling its activity.
