Glycogen synthase kinase 3 (GSK3) is implicated in multiple biological processes including metabolism, gene expression, cell fate determination, proliferation, and survival. Two closely related GSK3 isoforms encoded by distinct genes: GSK3a (51kD) and GSK3b (47kD). GSK3 activity is inhibited through phosphorylation of serine 21 in GSK3a and serine 9 in GSK3b. Serine 21 in GSK3a and serine 9 in GSK3b are also physiological substrates of cAMP-dependent protein kinase A. Studies in zebrafish model shows that GSK3a, but not GSK3b, is necessary in cardiomyocyte survival; the GSK3b plays important roles in modulating the left-right asymmetry and affecting heart positioning; and GSK3a and GSK3b play distinct roles during zebrafish cardiogenesis.
