N471D WASH complex subunit strumpellin knock-in mice display BPTF and KLHL11 dysregulation in brain tissue

We investigated brain tissue from N471D WASH complex subunit strumpellin knock-in mice as a genetic model for hereditary spastic paraplegia type 8. While WASHC5-related protein interaction partners and complexes showed no change in abundancies, the proteomic analysis depicted consistent upregulation of BPTF and downregulation of KLHL11 in heterozygous and homozygous knock-in mice. This finding suggests mechanistic links for hereditary spastic paraplegia type 8 through the roles of BPTF and KLHL11 in neurodegeneration and protein quality control, respectively.
