BAM1 (BRI1-associated receptor kinase 1) is a leucine-rich repeat receptor-like kinase (LRR-RLK) primarily studied in plants, notably in the model organism *Arabidopsis thaliana*. It localizes to the plasma membrane and plays a role in cell wall integrity maintenance, brassinosteroid (BR) signaling, and intercellular communication. BAM1 is structurally characterized by an extracellular LRR domain for ligand perception, a single transmembrane helix, and an intracellular kinase domain for signal transduction. Though initially identified as a paralog of the brassinosteroid receptor BRI1. BAM1 exhibits distinct functional roles. It interacts with co-receptors like BAK1 (BRI1-associated receptor kinase 1) to regulate developmental processes, including stomatal patterning, vascular development, and stress responses.
Recombinant BAM1 protein is engineered for in vitro studies to dissect its molecular mechanisms. Produced via heterologous expression systems (e.g., insect or mammalian cells), the purified protein retains post-translational modifications critical for functionality. Researchers use it to analyze kinase activity, ligand-binding specificity, and structural dynamics. Studies involving BAM1 have shed light on its dual role in BR signaling and cell wall surveillance, particularly its ability to sense cell wall damage and initiate repair signals. Its recombinant form also aids in crystallography and cryo-EM studies, revealing conformational changes during activation.
Beyond basic research, BAM1 has biotechnological potential. Modulating its activity could enhance crop resilience to environmental stresses or improve biomass production. However, functional redundancy with other RLKs and context-dependent signaling outcomes remain challenges. Ongoing work focuses on elucidating its interaction networks and downstream targets, bridging gaps between cell wall biology and hormone signaling pathways.
