Mitogen-activated protein kinase 8 interacting protein 3
JSAP1, JIP3, JNK-interacting protein 3
The protein encoded by this gene shares similarity with the product of Drosophila syd gene, required for the functional interaction of kinesin I with axonal cargo. Studies of the similar gene in mouse suggested that this protein may interact with, and regulate the activity of numerous protein kinases of the JNK signaling pathway, and thus function as a scaffold protein in neuronal cells. The C. elegans counterpart of this gene is found to regulate synaptic vesicle transport possibly by integrating JNK signaling and kinesin-1 transport. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008] (from
The results of this study finding suggested that a model by which the self-assembly of SYD-2/Liprin-alpha proteins mediated by the coiled-coil LH1 domain is one of the key steps to the accumulation of presynaptic components at nascent synaptic junctions

syd activates kinesin heavy chain for transport & enhances its motility, increasing its velocity & run length. syd mutants binding KHC but not kinesin light chain are transported to axons & dendrites normally.
