== Publication Abstract from PubMed ==
The light chains (KLCs) of the heterotetrameric microtubule motor kinesin-1, that bind to cargo adaptor proteins and regulate its activity, have a capacity to recognize short peptides via their tetratricopeptide repeat domains (KLC(TPR)). Here, using X-ray crystallography, we show how kinesin-1 recognizes a novel class of adaptor motifs that we call 'Y-acidic' (tyrosine flanked by acidic residues), in a KLC-isoform-specific manner. Binding specificities of Y-acidic motifs (present in JIP1 and in TorsinA) to KLC1(TPR) are distinct from those utilized for the recognition of W-acidic motifs, found in adaptors, that are KLC-isoform non-selective. However, a partial overlap on their receptor-binding sites implies that adaptors relying on Y-acidic and W-acidic motifs must act independently. We propose a model to explain why these two classes of motifs that bind to the concave surface of KLC(TPR) with similar low micromolar affinity can exhibit different capacities to promote kinesin-1 activity.
