Protein Name:
SNF1-related protein kinase catalytic subunit alpha KIN11
|
UniprotKB/SwissProt ID: P92958 (P92958)
Gene Name:
KIN11
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Catalytic subunit of the probable trimeric SNF1-related protein kinase (SnRK) complex, a central regulator of cellular energy homeostasis, which, in response to seemingly unrelated darkness, sugar and stress conditions, activates energy-producing pathways and inhibits energy-consuming processes. 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 (PubMed:17671505). In vitro, KIN11 exhibits kinase activity on sucrose phosphate synthase and the kinase activity is inhibited by PRL1 (PubMed:10220464). May be a subunit of a SCF ubiquitin ligase complex and thus be involved in proteasomal ubiquitination (PubMed:11387208). Involved in innate antiviral defenses (PubMed:12671096). Phosphorylates REM4.1 in vitro (PubMed:25289013). Phosphorylates ADK2 in vitro (PubMed:24498147)
