Beware of neuronal Sunday drivers: Sunday Driver interacts with two distinct classes of axonal organelles.
The extreme polarized morphology of neurons poses a challenging problem for intracellular trafficking pathways. The distant synaptic terminals must communicate via axonal transport with the cell soma for neuronal survival, function, and repair. Multiple classes of organelles transported along axons may establish and maintain the polarized morphology of neurons, as well as control signaling and ...
متن کاملSunday Driver links axonal transport to damage signaling
Neurons transmit long-range biochemical signals between cell bodies and distant axonal sites or termini. To test the hypothesis that signaling molecules are hitchhikers on axonal vesicles, we focused on the c-Jun NH2-terminal kinase (JNK) scaffolding protein Sunday Driver (syd), which has been proposed to link the molecular motor protein kinesin-1 to axonal vesicles. We found that syd and JNK3 ...
متن کاملKinesin-Dependent Axonal Transport Is Mediated by the Sunday Driver (SYD) Protein
A broadly conserved membrane-associated protein required for the functional interaction of kinesin-I with axonal cargo was identified. Mutations in sunday driver (syd) and the axonal transport motor kinesin-I cause similar phenotypes in Drosophila, including aberrant accumulations of axonal cargoes. GFP-tagged mammalian SYD localizes to tubulovesicular structures that costain for kinesin-I and ...
متن کاملTwo evolutionarily distinct classes of paleopolyploidy.
Whole genome duplications (WGDs) occurred in the distant evolutionary history of many lineages and are particularly frequent in the flowering plant lineages. Following paleopolyploidization in plants, most duplicated genes are deleted by intrachromosomal recombination, a process referred to as fractionation. In the examples studied so far, genes are disproportionately lost from one of the paren...
متن کاملPlasminogen interacts with human platelets through two distinct mechanisms.
Glu-plasminogen, the native form of plasminogen, interacts in a specific and saturable manner with unstimulated human platelets, and the binding is enhanced fivefold by thrombin stimulation (Miles and Plow, 1985. J. Biol. Chem. 260:4303). This study characterizes the nature of the Glu-plasminogen binding sites by analyzing platelets deficient in selected proteins and functions. Platelets from p...
