Nuclear localization signal in biology

Welcome to this fascinating exploration of the nuclear localization signal (NLS). Before we dive into the intricacies of NLS, let's understand the significance of the nucleus in a cell. The nucleus, often referred to as the 'brain' of the cell, houses the genetic material and orchestrates essential cellular processes. However, it's not an open space accessible to all molecules. The nucleus employs a complex system to regulate what enters and exits its domain, and the NLS plays a crucial role in this process.
