See full target information Slc3a2

Function

Acts as a chaperone that facilitates biogenesis and trafficking of functional transporters heterodimers to the plasma membrane. Forms heterodimer with SLC7 family transporters (SLC7A5, SLC7A6, SLC7A7, SLC7A8, SLC7A10 and SLC7A11), a group of amino-acid antiporters (PubMed:10574970, PubMed:10734121, PubMed:11011012, PubMed:9915839). Heterodimers function as amino acids exchangers, the specificity of the substrate depending on the SLC7A subunit. Heterodimers SLC3A2/SLC7A6 or SLC3A2/SLC7A7 mediate the uptake of dibasic amino acids. Heterodimer SLC3A2/SLC7A11 functions as an antiporter by mediating the exchange of extracellular anionic L-cystine and intracellular L-glutamate across the cellular plasma membrane (By similarity). SLC3A2/SLC7A10 translocates small neutral L- and D-amino acids across the plasma membrane (By similarity). SLC3A2/SLC75 or SLC3A2/SLC7A8 translocates neutral amino acids with broad specificity, thyroid hormones and L-DOPA. SLC3A2 is essential for plasma membrane localization, stability, and the transport activity of SLC7A5 and SLC7A8. When associated with LAPTM4B, the heterodimer SLC7A5 is recruited to lysosomes to promote leucine uptake into these organelles, and thereby mediates mTORC1 activation. Modulates integrin-related signaling and is essential for integrin-dependent cell spreading, migration and tumor progression (By similarity).

Activity summary

CD98 also known as CD98hc CD98 protein or LAT1/CD98 is a type II membrane protein often found in association with the heavy chains of amino acid transporters like LAT1. It has a molecular mass of approximately 85-100 kDa. CD98 is widely expressed in numerous tissues including the liver kidney and various tumors. It plays an important role in cellular processes by facilitating the transport of amino acids across plasma membranes which is essential for maintaining cellular homeostasis and proliferation.

Biological function summary

CD98 forms a complex with light chains of the heterodimeric amino acid transporters such as LAT1 and LAT2. This interaction enhances the uptake of neutral amino acids into cells. CD98 also interacts with integrins influencing cell adhesion and migration which are critical for cellular signaling and response. Through these interactions CD98 impacts not only cell survival and growth but also immune responses and angiogenesis.

Pathways

CD98 is a vital component of the mTOR signaling pathway influencing cell growth and proliferation. It also plays a part in the integrin signaling pathway which regulates cell adhesion and migration. In these pathways CD98 works closely with proteins like FG1 and mTORC1. These relationships enable it to modulate cellular responses to nutritional availability and mechanical cues from the environment.

Associated diseases and disorders

CD98 expression and function have links to cancer and autoimmune diseases. High expression levels of CD98 are observed in various cancers such as lymphomas where it correlates with increased tumor growth and poor prognosis. In autoimmune disorders like rheumatoid arthritis CD98 influences immune cell activation and migration. Proteins such as CP1 and FG1 interact with CD98 contributing to disease pathology by affecting cellular and immune responses.
