Annotation description:"To investigate the effects of SNX26 on dendritic spine formation, cultured hippocampal neurons at DIV 13 were co-transfected with GFP or GFP-SNX26 and with mCherry empty vector (23) and then fixed at DIV 14. SNX26 overexpression induced an ~38.2% decrease in total dendritic protrusions.

To identify which domain(s) of SNX26 may be responsible for the observed effects, neurons were co-transfected with mCherry and various deletion mutants of SNX26. Among the mutants, only the RhoGAP domain showed effects similar to those of SNX26 FL (Fig. 6), indicating that the RhoGAP domain is responsible for the effects of SNX26 on dendritic spine formation. This was confirmed by results from a GAP-defective mutant of SNX26 (R350I), which showed a comparable level of dendritic spine development to that in the control group (Fig. 7)."
