Glutamine Transporter

Molecular classification
Transporter, Solute Carrier (SLC), SLC1 family, SLC6 family, SLC7 family, SLC38 family
01

Overview

Glutamine transporters are membrane proteins that facilitate the movement of glutamine across cellular membranes. They belong to several solute carrier (SLC) gene families, including SLC1, SLC6, SLC7 and SLC38. These transporters play crucial roles in nutrient absorption, reabsorption, neurotransmitter cycling, and metabolic regulation. ASCT2/SLC1A5 is a major glutamine transporter, particularly in cancer cells, and its inhibition is explored as a therapeutic strategy. They utilize Na+-dependent symport or antiport mechanisms.
