| + | [https://www.uniprot.org/uniprot/KLC2_MOUSE KLC2_MOUSE] Kinesin is a microtubule-associated force-producing protein that plays a role in organelle transport. The light chain functions in coupling of cargo to the heavy chain or in the modulation of its ATPase activity. Through binding with PLEKHM2 and ARL8B, recruits kinesin-1 to lysosomes and hence direct lysosomes movement toward microtubule plus ends.[UniProtKB:Q9H0B6] | ||

| + | 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. | ||
