Stimulation by cholesterol of glutamine and arginine transport was observed. The biological function of SLC38A9 relies on the interaction between its N-terminus and components of the mTOR complex; a deletion mutant of the N-terminus tail was produced and transport of glutamine was assayed revealing...
CholesterolGlutamineTransceptorhSLC38A9The lysosomal amino acid transporter SLC38A9 is referred to as transceptor, i.e. a transporter with a receptor function. The protein is responsible for coupling amino acid transport across the lysosomal membrane according to the substrate availability to mTORC1 ...
