STRINGSTRING
PPCK1 protein (Arabidopsis thaliana) - STRING interaction network
"PPCK1" - Encodes a phosphoenolpyruvate carboxylase kinase that is expressed at highest levels in leaves. Expression is induced by light in Arabidopsis thaliana
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

PPCK1Encodes a phosphoenolpyruvate carboxylase kinase that is expressed at highest levels in leaves. Expression is induced by light; Belongs to the protein kinase superfamily. Ser/Thr protein kinase family (284 aa)    
Predicted Functional Partners:
PPC3
Encodes a cytosolic phosphoenolpyruvate carboxylase (PEPC) that has activity when expressed in E.coli. Its mRNA is most abundantly expressed in roots and siliques. PPC3 belongs to the plant-type PEPC family. It can form an enzymatically active complex with a castor bean ortholog of PPC4, which encodes a bacterial-type PEPC (968 aa)
     
   
  0.843
PPC2
Phosphoenolpyruvate carboxylase 2; Through the carboxylation of phosphoenolpyruvate (PEP) it forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle (963 aa)
     
   
  0.704
PEPC1
Pyridoxal phosphate phosphatase-related protein; Catalyzes the specific cleavage of pyrophosphate (279 aa)
     
   
  0.589
PPC4
Phosphoenolpyruvate carboxylase 4; Encodes one of four Arabidopsis phosphoenolpyruvate (PEP) carboxylase proteins. But, it is more similar to bacterial PEP carboxylase than plant PEP carboxylase. Efforts to express this enzyme and to demonstrate its enzymatic activity in E.coli failed; Belongs to the PEPCase type 1 family (1032 aa)
     
   
  0.587
PERK15
Proline-rich receptor-like protein kinase PERK15; Protein kinase superfamily protein; Its function is described as protein kinase activity, ATP binding; Involved in protein amino acid phosphorylation; Located in plasma membrane; Expressed in 23 plant structures; Expressed during 14 growth stages; Contains the following InterPro domains- Protein kinase, ATP binding site (InterPro-IPR017441), Protein kinase, catalytic domain (InterPro-IPR000719), Serine-threonine/tyrosine-protein kinase (InterPro-IPR001245), Protein kinase-like domain (InterPro-IPR011009); BEST Arabidopsis thaliana prote [...] (509 aa)

AT4G02720
Ras-induced vulval development antagonist protein; Unknown protein; Its function is described as molecular_function unknown; Involved in biological_process unknown; Expressed in 25 plant structures; Expressed during 14 growth stages; Contains the following InterPro domains- Protein of unknown function DUF926 (InterPro-IPR009269); Has 30201 Blast hits to 17322 proteins in 780 species- Archae - 12; Bacteria - 1396; Metazoa - 17338; Fungi - 3422; Plants - 5037; Viruses - 0; Other Eukaryotes - 2996 (source- NCBI BLink) (422 aa)

MDH
Malate dehydrogenase, chloroplastic; Catalyzes a reversible NAD-dependent dehydrogenase reaction involved in central metabolism and redox homeostasis between organelle compartments (Probable). Plays a key role in the metabolism of dark chloroplasts and non-green plastids. Essential for embryo viability. Plays an essential role in heterotrophic metabolism in embryos, and autotrophic metabolism in photosynthetic tissues as well (403 aa)
           
  0.553
NAKR1
Heavy metal transport/detoxification superfamily protein; Required for root meristem maintenance after germination. Involved in phloem translocation, starch accumulation and flowering. Promotes flowering in the photoperiod pathway. Regulates long- distance movement of FT from leaves to the shoot apex through the phloem stream (319 aa)
           
  0.551
PPDK
Encodes a dual-targeted protein believed to act as a pyruvate, orthophosphate dikinase. These enzymes are normally associated with C4 photosynthesis which does not occur in Arabidopsis. However, PPDK may play a role in remobilizing nitrogen during leaf senescence in Arabidopsis. The product of the long transcript (.1 gene model) was shown to be targeted to the chloroplast, whereas the shorter transcript (no targeting sequence) accumulates in the cytosol. The two proteins were also found to be expressed in slightly different tissues (963 aa)
           
  0.551
SQD2
Sulfoquinovosyl transferase SQD2; Catalyzes the transfer of the sulfoquinovose moiety from UDP-sulfoquinovose to diacylglycerol during sulfolipid biosynthesis. Sulfolipid contributes to maintaining a negatively charged lipid-water interface, a requirement for proper function of photosynthetic membranes. Sulfolipid may also function as a substitute of anionic phospholipids under phosphate-limited growth conditions (510 aa)
