BRASSINOSTEROID-SIGNALING KINASE 3, a plasma membrane-associated scaffold protein involved in early brassinosteroid signaling
Brassinosteroids (BRs) are steroid hormones that regulate numerous processes throughout the plant life cycle. In this study, Ren et al investigate the function of BRASSINOSTEROID-SIGNALING KINASE 3 (BSK3) in BR signaling and plant growth and development. The authors find evidence for BSK3 functioning as a scaffold protein and describe new layers of regulation in BR signaling.
