Kinase Classification: PPP Kelch※ Kelch family introduction Kelch phosphatases are PPP family phosphatase contain tandem N-terminal kelch-repeat. Four members in Arabidopsis have been found, known as BSU1, BSL1, BSL2 and BSL3. Kelch phosphatases are able to dephosphorylate BES1 and play an essential role in the regulation of response to brassinosteroids (1).
