CRISPR/Cas knockout of intraflagellar transport protein 80 shows that this subunit is absolutely required for ciliogenesis, and biophysical studies reveal that this protein may dimerize the intraflagellar transport complex.
Carbonic anhydrase II features a surface proton antenna that exclusively mediates proton exchange with monocarboxylate transporters to facilitate proton-coupled lactate transport in cancer cells.
Auxiliary proteins play functional roles in modulating the assembly and activity of a non-canonical ABC transporter that is important for the maintenance of outer membrane lipid asymmetry.
Selective import via bacterial ABC importers is facilitated by a hitherto unrecognized complexity in the conformational dynamics of the substrate-binding proteins.
A novel regulatory step in the endocytic pathway, which occurs post-internalization, takes place at the trans-Golgi network and involves the arrestin-related protein Rod1 and the ubiquitin ligase Rsp5.
The conformational mechanism of a transporter protein is found to have profound and energetically costly effects on the morphology of the surrounding membrane.
Molecular analysis of cholesterol transport by NPC1 and NPC1L1 proteins reveals that cholesterol likely moves through these transporters, and ezetimibe blocks NPC1L1 by binding at the interface between multiple domains.
The conserved polypeptide transport associated (POTRA) domains of the protein import channel, Toc75, are essential for protein import into chloroplasts.
