Application
Bikinin has been used:
- as a glycogen synthase kinase-3 (GSK3) inhibitor in Arabidopsis Col-0 seedlings to test its effect on gene expression
- as a component of induction medium and as a GSK3 inhibitor to test its effect on mesophyll cells in Arabidopsis leaf discs or cotyledons
- as a brassinosteroid agonist to test its effect on the leaf index of R. trichophyllus terrestrial leaves
Biochem/physiol Actions
Bikinin is a strong activator of brassinosteroid (BR) signaling. It is an Arabidopsis GSK-3 Inhibitor, an Arabidopsis SHAGGY-related Kinase Inhibitor, and a GSK-3-like Kinase BIN2 Inhibitor. Bikinin directly inhibits BIN2 (group II GSK3s) by interfering with ATP binding. Bikinin is specific toward a subset of Arabidopsis GSK3 kinases including BIN2 and ASK α, γ, ε, ι, and θ.
Inhibitor of Arabidopsis GSK-3, SHAGGY-related Kinase, and GSK-3-like Kinase BIN2

Glycogen synthase kinase 3 (GSK3) is a key regulator in signaling pathways in both animals and plants. Three Arabidopsis thaliana GSK3s are shown to be related to brassinosteroid (BR) signaling. In a phenotype-based compound screen we identified bikinin, a small

Casein kinase 1 (CK1) is an evolutionarily conserved protein kinase family among eukaryotes. Studies in non-plants have shown CK1-dependent divergent biological processes, but the collective knowledge regarding the biological roles of plant CK1 lags far behind other members of the

Grain size is a key agronomic trait that determines the yield in plants. Regulation of grain size by brassinosteroids (BRs) in rice has been widely reported. However, the relationship between the BR signaling pathway and grain size still requires further
