UASt regulatory sequences drive expression of a mutated form of the fusion protein associated with the mouse 'Wld[S]' mutation. The 'Wld[S]' fusion protein is composed of the N-terminal 70 amino acids of Mmus\Ube4b, a unique 18 amino acid domain generated during the fusion event and the full-length sequence of Mmus\Nmnat1. In this transgene, an H24A amino acid replacement has been introduced into the fusion protein sequence (this mutation largely abolishes Mmus\Nmnat1 enzymatic activity).
Expression of one copy of Mmus\wldS-dead.Scer\UAS under the control of Scer\GAL4VGlut-OK371 has a moderate protective effect on L1 vein neurons following axotomy. Fragmentation of axons occurs more slowly than in wild type.
Expression of Mmus\wldH24A.Scer\UAS in the ddaC neurons (using the Scer\GAL4ppk.PG line) has no protective effect on dendritic pruning as when Mmus\wldS.Scer\UAS is expressed.
Expression of Mmus\wldS-dead.Scer\UAS under the control of Scer\GAL4Or22a.8197 has very little protective effect on olfactory receptor neurons following axotomy: 92% of olfactory receptor neuron axons have undergone Wallerian degeneration within 15 days of injury.
