Supplementary information

The SLC1A5 protein also known as ASCT2 is a sodium-dependent neutral amino acid transporter with a molecular mass of approximately 56 kDa. It plays an important role in the transport of amino acids such as glutamine across the plasma membrane. This transporter is widely expressed in multiple tissues including the liver brain and kidneys. ASCT2 is integral in maintaining amino acid balance within cells facilitating nutrient uptake essential for cellular metabolism and function.
Biological function summary

The SLC1A5 protein contributes to cellular processes by facilitating the uptake of neutral amino acids. ASCT2 operates as a part of a complex of transporters that ensure the supply of critical nutrients within cells impacting metabolic processes like protein synthesis and cell growth. Its function supports the dynamic needs of rapidly growing tissues and is especially active in conditions demanding high amino acid turnover.

Pathways

The activity of SLC1A5/ASCT2 is important in amino acid transport pathways particularly influencing the mTOR signaling which plays a significant role in cell growth and metabolic regulation. SLC1A5/ASCT2 interaction with proteins like LAT1 strengthens its involvement in these pathways. These interactions outline a network of nutrient sensing and metabolic control important for cellular proliferation and homeostasis.

SLC1A5/ASCT2 shows a significant connection to cancer as many cancer cells exploit its role in glutamine transport to fuel their rapid growth and survival. Additionally its involvement is noted in metabolic disorders where dysregulated amino acid transport can lead to imbalances in cellular metabolism. SLC1A5/ASCT2 has potential interactions with proteins like glutaminase which are often upregulated in oncogenic pathways highlighting its importance as a target for therapeutic interventions.

Target data

Sodium-coupled antiporter of neutral amino acids. In a tri-substrate transport cycle, exchanges neutral amino acids between the extracellular and intracellular compartments, coupled to the inward cotransport of at least one sodium ion (PubMed : 17094966, PubMed : 23756778, PubMed : 26492990, PubMed : 29872227, PubMed : 34741534, PubMed : 8702519). The preferred substrate is the essential amino acid L-glutamine, a precursor for biosynthesis of proteins, nucleotides and amine sugars as well as an alternative fuel for mitochondrial oxidative phosphorylation. Exchanges L-glutamine with other neutral amino acids such as L-serine, L-threonine and L-asparagine in a bidirectional way. Provides L-glutamine to proliferating stem and activated cells driving the metabolic switch toward cell differentiation (PubMed : 23756778, PubMed : 24953180). The transport cycle is usually pH-independent, with the exception of L-glutamate. Transports extracellular L-glutamate coupled to the cotransport of one proton and one sodium ion in exchange for intracellular L-glutamine counter-ion. May provide for L-glutamate uptake in glial cells regulating glutamine/glutamate cycle in the nervous system (PubMed : 32733894). Can transport D-amino acids. Mediates D-serine release from the retinal glia potentially affecting NMDA receptor function in retinal neurons (PubMed : 17094966). Displays sodium- and amino acid-dependent but uncoupled channel-like anion conductance with a preference SCN(-) >> NO3(-) > I(-) > Cl(-) (By similarity). Through binding of the fusogenic protein syncytin-1/ERVW-1 may mediate trophoblasts syncytialization, the spontaneous fusion of their plasma membranes, an essential process in placental development (PubMed : 10708449, PubMed : 23492904).. (Microbial infection) Acts as a cell surface receptor for Feline endogenous virus RD114.. (Microbial infection) Acts as a cell surface receptor for Baboon M7 endogenous virus.. (Microbial infection) Acts as a cell surface receptor for type D simian retroviruses.
