Gene symbol: SIP4
Gene description: SOS3-interacting protein 4
Primary source: Araport:AT2G30360
Locus tag: AT2G30360
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: CBL-INTERACTING PROTEIN KINASE 11; CIPK11; PKS5; PROTEIN KINASE SOS2-LIKE 5; SNF1-RELATED PROTEIN KINASE 3.22; SNRK3.22; SOS3-interacting protein 4; T9D9.17; T9D9_17
Summary: Encodes a SOS2-like protein kinase that is a member of the CBL-interacting protein kinase family.Loss of function mutants show a decrease in sensitivity to high pH.Phosphorylates AHA2, a plasma membrane H+ ATPase.This phosphorylation appears to regulate the activity of the proton transporter.

The kinase CIPK11 functions as a positive regulator in cadmium stress response in Arabidopsis.
Title: The kinase CIPK11 functions as a positive regulator in cadmium stress response in Arabidopsis.
The overexpression of CIPK11 (CIPK11OE) in Arabidopsis resulted in the decreased tolerance of plant to drought stress. CIPK11 partly mediates the drought stress response by regulating the transcription factor Di19-3.
Title: The Kinase CIPK11 Functions as a Negative Regulator in Drought Stress Response in Arabidopsis.
propose that Ca(2+)-triggered CBL1/9-mediated activation of CIPK11 and subsequent phosphorylation of FIT shifts inactive into active FIT, allowing regulatory protein interactions in the nucleus
Title: CIPK11-Dependent Phosphorylation Modulates FIT Activity to Promote Arabidopsis Iron Acquisition in Response to Calcium Signaling.
SOS2-LIKE PROTEIN KINASE5 (PKS5) can negatively regulate the Salt-Overly-Sensitive signaling pathway in Arabidopsis. PKS5 can interact with and phosphorylate SOS2 at Ser294, promote the interaction between SOS2 and 14-3-3 proteins, and repress SOS2 activity. However, salt stress promotes an interaction between 14-3-3 proteins and PKS5, repressing its kinase activity and releasing inhibition of SOS2.
Title: Calcium-activated 14-3-3 proteins as a molecular switch in salt stress tolerance.
PKS5-mediated phosphorylation of ABI5 at Ser-42 is critical for the abscissic acid regulation of seed germination and gene expression in Arabidopsis.
Title: SOS2-LIKE PROTEIN KINASE5, an SNF1-RELATED PROTEIN KINASE3-Type Protein Kinase, Is Important for Abscisic Acid Responses in Arabidopsis through Phosphorylation of ABSCISIC ACID-INSENSITIVE5.
PKS5 involves in external high pH signal mediated microfilament depolymerization, and that may be independent of calcium signal.
Title: The alkaline tolerance in Arabidopsis requires stabilizing microfilament partially through inactivation of PKS5 kinase.
results suggest that PKS5 functions at the upstream of NPR1 and might mediate expression of WRKY38 and WRKY62 possibly by interacting with and phosphorylating NPR1.
Title: PKS5, a SNF1-related kinase, interacts with and phosphorylates NPR1, and modulates expression of WRKY38 and WRKY62.
J3 regulates plasma membrane H+-ATPase activity through interaction with the PKS5 kinase.
Title: The Arabidopsis chaperone J3 regulates the plasma membrane H+-ATPase through interaction with the PKS5 kinase.
These results suggest that PKS5 is part of a calcium-signaling pathway mediating PM H+ -ATPase regulation.
Title: Arabidopsis protein kinase PKS5 inhibits the plasma membrane H+ -ATPase by preventing interaction with 14-3-3 protein.
