BRI1/BAK1, a Receptor Kinase Pair Mediating Brassinosteroid Signaling
The Arabidopsis BAK1 (BRI1 Associated receptor Kinase 1) was identified by a yeast two-hybrid screen as a specific interactor for BRI1, a critical component of a membrane brassinosteroid (BR) receptor. In yeast, BAK1/BRI1 interaction activates their kinase activities through transphosphorylation. BAK1 and BRI1 share similar gene expression and subcellular localization patterns and physically as...
متن کاملIN THIS ISSUE Brassinosteroid Perception and Signaling: Heterodimerization and Phosphorylation of Receptor-Like Kinases BRI1 and BAK1
Brassinosteroids (BRs) are plant growth hormones that are structurally similar to insect and animal steroids. Since the discovery of BRs in Brassica napus pollen, more than 40 BR-like compounds have been identified in numerous plant species (Altmann, 1999). BRs show a strong growth-promoting effect when applied to plants in nanomolar concentrations because of positive effects on both cell divis...
متن کاملHeterodimerization and endocytosis of Arabidopsis brassinosteroid receptors BRI1 and AtSERK3 (BAK1).
In Arabidopsis thaliana brassinosteroid (BR), perception is mediated by two Leu-rich repeat receptor-like kinases, BRASSINOSTEROID INSENSITIVE1 (BRI1) and BRI1-ASSOCIATED RECEPTOR KINASE1 (BAK1) (Arabidopsis SOMATIC EMBRYOGENESIS RECEPTOR-like KINASE3 [AtSERK3]). Genetic, biochemical, and yeast (Saccharomyces cerevisiae) interaction studies suggested that the BRI1-BAK1 receptor complex initiate...
متن کاملVisualization of BRI1 and BAK1(SERK3) membrane receptor heterooligomers during brassinosteroid signaling.
The leucine-rich repeat receptor-like kinase BRASSINOSTEROID-INSENSITIVE1 (BRI1) is the main ligand-perceiving receptor for brassinosteroids (BRs) in Arabidopsis (Arabidopsis thaliana). Binding of BRs to the ectodomain of plasma membrane (PM)-located BRI1 receptors initiates an intracellular signal transduction cascade that influences various aspects of plant growth and development. Even though...
متن کاملBAK1, an Arabidopsis LRR Receptor-like Protein Kinase, Interacts with BRI1 and Modulates Brassinosteroid Signaling
Brassinosteroids regulate plant growth and development through a protein complex that includes the leucine-rich repeat receptor-like protein kinase (LRR-RLK) brassinosteroid-insensitive 1 (BRI1). Activation tagging was used to identify a dominant genetic suppressor of bri1, bak1-1D (bri1-associated receptor kinase 1-1Dominant), which encodes an LRR-RLK, distinct from BRI1. Overexpression of BAK...
