Substrate releasing or inhibitor binding on the intracellular side of a glutamate transporter homologue require movements of the transport domain through the lipid membrane, which undergoes adaptive deformations.

The high-resolution x-ray structure of an asymmetrical SeCitS dimer, present in the inward- and outward-facing state, provides a complete mechanism of substrate and ion translocation in a sodium-dependent symporter.
Sterol transport by Niemann-Pick type C proteins induces the expansion of raft-like domains in the yeast vacuole, enabling engulfment of lipid droplets by microautophagy.

The structure of an NRAMP-related Al3+ transporter illustrates the evolution of a branch of a conserved protein family of metal ion transporters in plants to combat Al3+ toxicity in acidic soil.

The structure of the potassium-chloride cotransporter KCC4 provides insight into the basis of ion specificity, transport stoichiometry, and activity regulation for a broadly physiologically and clinically important transporter family.
The amino acids that are necessary for phospholipid scrambling by ANO6/TMEM16F can, via domain swapping, confer scrambling activity to the chloride ion channel ANO1 that normally does not scramble phospholipids.

Structure of the dimeric Haemophilus influenzae TRAP transporter (SiaQM) reveals two Na+ sites, the substrate-binding site and lipid-binding sites, and weak but promiscuous binding of SiaP to SiaQM.
