SLC35F1 (Solute Carrier Family 35 Member F1) is a gene that encodes a protein responsible for transporting nucleotide sugars across cell membranes. These sugars are crucial for glycosylation — an essential process that modifies proteins, impacting their folding, stability, and function. By facilitating proper glycosylation, SLC35F1 plays a key role in sustaining cellular function, immune response, and may influence disease mechanisms such as cancer.
