Ligands: Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Publication Abstract from PubMed Kinesin-mediated cargo transport is required for many cellular functions and plays a key role in pathological processes. Structural information on how kinesins recognize their cargoes is required for a molecular understanding of this fundamental and ubiquitous process. Here, we present the crystal structure of the tetratricopeptide repeat of kinesin light chain 2 in complex with a cargo peptide harboring a 'tryptophan-acidic' motif derived from SKIP, a critical host determinant in Salmonella pathogenesis and a regulator of lysosomal positioning. Structural data together with biophysical, biochemical, and cellular assays allow us to propose a framework for intracellular transport based on the binding by kinesin-1 of W-acidic cargo motifs through a combination of electrostatic interactions and sequence-specific elements, providing direct molecular evidence of the mechanisms for kinesin-1:cargo recognition.
