Axons and their synapses distal to an injury undergo rapid Wallerian degeneration, but axons in the C57BL/WldS mouse are protected. The degenerative and protective mechanisms are unknown. We identified the protective gene, which encodes an N-terminal fragment of ubiquitination factor E4B (Ube4b) fused to nicotinamide mononucleotide adenylyltransferase(More)
Wallerian degeneration is the degeneration of the distal stump of an injured axon. It normally occurs over a time course of around 24 hr but it is delayed in the slow Wallerian degeneration mutant mouse (C57BL/Wlds) for up to 3 weeks. The gene, which protects from rapid Wallerian degeneration, Wld, previously has been mapped to distal chromosome 4. This(More)
Kinesin and kinesin superfamily proteins are molecular motors involved in important intracellular functions such as organelle transport and cell division. They are microtubule-activated ATPases composed of a motor domain that binds to microtubules and a cargo-binding domain that binds to specific organelles. While searching for the slow Wallerian(More)
