2.A.18.9.2 SLC38A9 of 549 aas and 111 TMSs. The crystal structure of this lysosomal transporter with arginine bound in the inward facing conformation has been solved (Lei et al. 2018). The bound arginine was locked in a transitional state stabilized by TMS1, which was anchored at the groove between TM5 and TM7. These anchoring interactions were mediated by the highly conserved WNTMM motif in TMS1, and mutations in this motif abolished arginine transport (Lei et al. 2018).
