Tsr1

Tsr1 is a protein involved in the early stages of assembling ribosomes, which are the cell's protein-making machines. Specifically, Tsr1 helps guide the proper formation of the small ribosomal subunit within the cell's nucleus before it becomes fully functional in the cytoplasm. It acts as a sort of assembly helper, ensuring that the ribosome components are correctly assembled so they can efficiently produce proteins essential for various cellular functions.
