Crosstide

Research use only, not for human use.

Crosstide is a peptide analog of glycogen synthase kinase-3 (GSK-3) that functions as a natural substrate for Akt/PKB.

Crosstide is a peptide analog of glycogen synthase kinase-3 (GSK-3) that functions as a natural substrate for Akt/PKB.(In Vitro):16HBE14o cells exposed to RV39 demonstrate a crosstide kinase activity in vitro. Serine phosphorylation of crosstide is confirmed by immunoblotting, and phosphorylation is blocked by PP2 but not by PP3. The wildtype GST-AKT2 shows significant phosphoryl transferase activity towards crosstide, reaching an initial velocity of 16 pmol phosphate/min/μg enzyme. The mutant GST-AKT2T/E,S/D displayed an initial velocity of 85 pmol phosphate/min/μg kinase for phosphorylation of Crosstide, corresponding to a 5-fold increase compared to the wildtype enzyme.
