During Brassinosteroid (BR) signal transduction pathway two forms exist,

1) In absence of Brassinolide

2) In presence of Brassinolide

a) BKI1 is phosphorylated and dissociates from the plasma membrane

b) BRI1 phosphorylation, and promotes BRI1–BAK1 heterodimerization, bringing their cytoplasmic domains together for interaction, transphosphorylation

c) BRI1 and BAK1 can form homodimers and both undergoes endocytosis and recycling

d) BIN2 kinases Phosphorylate transcriptional factor BES1 and BZR1 and these Phosphorylated proteins are shortlived and are degraded in the proteasome

e) BSK proteins activate BSU1 phosphatase which dephosphorylated BIN2 is degraded by the proteasome system

f) In absence of BIN2, dephosphorylated  transcriptional factor BES1 and BZR1 form heterodimers with different transcription factors and bind E-box sequences to activate genes.
