Protein

Serine/threonine-protein phosphatase BSU1

Gene

BSU1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Phosphatase that acts as a positive regulator of brassinosteroid (BR) signaling (PubMed:14977918, PubMed:21855796). Dephosphorylates BES1, a transcription factor that regulates the expression of BR-response genes, thereby playing an important role in the regulation of response to BRs (PubMed:14977918). Inactivates the negative regulator of BR signaling ASK7/BIN2 by dephosphorylation at 'Tyr-200' (PubMed:21855796).2 Publications

Expressioni

Tissue specificityi

Mainly expressed in young, elongating tissues. In young seedlings, it is expressed at the base of the hypocotyl, at the tip and most peripheral cell layers of cotyledons, and in the vascular cylinder of roots, particularly in the elongation zone and at the point of emergence of lateral roots. In mature plants, it is still present in the root vasculature, but almost completely absent in fully expanded stems and leaves. In flowers, it is mainly expressed in sepal veins, anther filaments, and in the style, suggesting that BSU1 is expressed in actively growing regions and apparently enriched in vascular tissues.1 Publication
