Protein

SNF1-related protein kinase catalytic subunit alpha KIN11

Gene

KIN11

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

Functioni

Catalytic subunit of the probable trimeric SNF1-related protein kinase (SnRK) complex, which may play a role in a signal transduction cascade regulating gene expression and carbohydrate metabolism in higher plants. The SnRK complex may also be involved in the regulation of fatty acid synthesis by phosphorylation of acetyl-CoA carboxylase and in assimilation of nitrogen by phosphorylating nitrate reductase. In vitro, KIN11 exhibits kinase activity on sucrose phosphate synthase and the kinase activity is inhibited by PRL1. May be a subunit of a SCF ubiquitin ligase complex and thus be involved in proteasomal ubiquitination. Involved in innate antiviral defenses.2 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Enzyme regulationi

Inactivated by the begomovirus AL2 protein or the curtovirus L2 protein. Activated by phosphorylation at Thr-176.2 Publications

Interactioni

Subunit structurei

Subunit of a probable heterotrimeric complex consisting of an alpha catalytic (KIN10 or KIN11) subunit, and a beta (KINB) and a gamma (KING or SNF4) non-catalytic regulatory subunits. Interacts with KINB2, KINB3, SNF4 and probably with KINB1 and KING1. Interacts with SKP1/ASK1, PAD1 and the N-terminus of PRL1. Potential subunit of a SCF ubiquitin ligase complex consisting of a SNF1-related protein kinase, SKP1 and CUL1. The association of the SCF complex with the proteasome may be mediated by PAD1 and seems to be inhibited by the interaction with PRL1. Interacts with DSP4. Interacts with the begomovirus AL2 protein and the curtovirus L2 protein.8 Publications
