Targeted expression1 |
Restored
Description: Reexpression of nlgn3 specifically in adult purkinje cells increased nlgn3 protein expression in purkinjee cell dendrites in the cerebellum not in the inner granular layer, compared to mutants. the reexpression of nlgn3 in pcs exceeds the endogenous nlgn3 expression level and results in a gain-of-function phenotype.
Exp Paradigm: Calbindin is used to co-stain for dendrite identification.-western blot
