Phosphorylates BRASSINOSTEROID INSENSITIVE 1 (BRI1). May be involved in changing the equilibrium between plasma membrane-located BRI1 homodimers and endocytosed BRI1-BAK1 heterodimers.CATALYTIC ACTIVITY:ATP a protein = ADP a phosphoprotein.SUBUNIT:Heterodimer with BRI1 in the Endosomes.INTERACTION:Q9ZWC8:BRL1; NbExp=3; IntAct=EBI-617138, EBI-590903;TISSUE SPECIFICITY:Expressed ubiquitously.DOMAIN:Contains one leucine-zipper motif and one pair of conservatively spaced Cys (Cys pair) involved in forming heterodimers.MISCELLANEOUS:Interaction with BRI1 activates both receptor kinases and the full activation of either receptor kinase requires transphosphorylation by their partners. Autophosphorylates in vitro on Ser and Thr but not on Tyr.SIMILARITY:Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.SIMILARITY:Contains 4 LRR (leucine-rich) repeats.SIMILARITY:Contains 1 protein kinase domain.SEQUENCE CAUTION:Sequence=CAB38801.1; Type=Erroneous gene model prediction; Sequence=CAB80060.1; Type=Erroneous gene model prediction; "
