KCl-induced activity decreases Cdk5-phosphorylated CRMP2. (A) Timeline of experimental procedures. (B) Schematic of GSK3β and Cdk5 phosphorylation sites within the rat CRMP2 sequence. Numbers represent amino acid residues within the CRMP2 sequence. (C) Representative immunoblots of Cdk5-phosphorylated CRMP2 (CRMP2 pSer522) and β III-tubulin from naïve cortical neurons compared to those exposed to KCl for 30 min or 96 h. (D) KCl exposure lead to a time-dependent decrease in the level of Cdk5-phosphorylated CRMP2 (CRMP2 pSer522) (*p < 0.05 compared to control and #p < 0.05 compared to 30 min KCl treatment; One-Way ANOVA, Tukey's post-hoc analysis; n = 5).
