  • Title: Interaction of a protein phosphatase with an Arabidopsis serine-threonine receptor kinase.
    Author: Stone JM, Collinge MA, Smith RD, Horn MA, Walker JC.
    Journal: Science; 1994 Nov 04; 266(5186):793-5. PubMed ID: 7973632.
    Abstract:
    A protein phosphatase was cloned that interacts with a serine-threonine receptor-like kinase, RLK5, from Arabidopsis thaliana. The phosphatase, designated KAPP (kinase-associated protein phosphatase), is composed of three domains: an amino-terminal signal anchor, a kinase interaction (KI) domain, and a type 2C protein phosphatase catalytic region. Association of RLK5 with the KI domain is dependent on phosphorylation of RLK5 and can be abolished by dephosphorylation. KAPP may function as a signaling component in a pathway involving RLK5.
