"CSK" - Chloroplast sensor kinase in Arabidopsis thaliana
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 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
protein homology
Your Input:
Gene Fusion
CSKChloroplast sensor kinase; Sensor kinase required for sensing the plastoquinone redox state involved in both photosystems stoichiometry adjustment (e.g. long-term adaptation via transcriptional regulation of reaction center genes of photosystems I and II) and state transitions (e.g. short-term adaptation involving reversible post- translational phosphorylation of light-harvesting complex II, LHC II), thus linking photosynthesis with gene expression in chloroplasts (PubMed-18632566, PubMed-22039472). Probably phosphorylates SIGA/SIG1 in response to plastoquinone redox state modification [...] (611 aa)    
Predicted Functional Partners:
STT7 homolog STN7; Serine/threonine protein kinase required for state transition by phosphorylating light-harvesting complex II outer antennae (LCHII). State transition plays a central role in response to environmental changes and allows to adjust to changing light conditions via the redistribution of light excitation energy between photosystem II (PSII) and photosystem I (PSI). Phosphorylates the minor light harvesting protein LHCB4.2/CP29 and is involved in the light-dependent phosphorylation of TSP9. Acts as a key component of the long-term response (LTR) signaling pathway. Mediates [...] (562 aa)
uvrB/uvrC motif-containing protein (330 aa)
Protein phosphatase 2C 57 (388 aa)
State transition 8; Light-dependent serine/threonine protein kinase that specifically phosphorylates N-terminal threonine residues in psbA/D1, psbD/D2, psbC/CP43 and psbH, which are components of the core antenna complex of photosystem II. Phosphorylation of PSII core components facilitates the exchange of chlorophyll proteins between the grana and the stroma lamellae. Also involved in the phosphorylation of the calcium-sensing receptor (CaS) (495 aa)
Casein kinase 2, alpha polypeptide; Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. The alpha chain contains the catalytic site. May act as an ectokinase that phosphorylates several extracellular proteins (By similarity) (432 aa)
Sigma factor A; Essential protein. Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released. Controls the transcription of the psaA gene and thus modulates photosystem stoichiometry. Thereby maintains a harmonious electron flow and photosynthetic efficiency (502 aa)
Lipoic acid synthase 1; Catalyzes the radical-mediated insertion of two sulfur atoms into the C-6 and C-8 positions of the octanoyl moiety bound to the lipoyl domains of lipoate-dependent enzymes, thereby converting the octanoylated domains into lipoylated derivatives (374 aa)
F-box protein SKIP28; Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity). Required during the endosperm development in embryos (292 aa)
RNApolymerase sigma subunit 2; Required for the transition of plastids into chloroplasts by coordinating nuclear and chloroplastic genomes under light conditions. Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released. Promotes the biosynthesis of plastid-encoded tRNAs (e.g. trnE-UUC and trnV- UAC) (572 aa)
Protein CHUP1; Required for the positioning and movement of chloroplasts. Interacts with profilin and actin independent of its polymerization status. Regulates chloroplast localization by anchoring chloroplasts to the plasma membrane and forming a bridge to the actin cytoskeleton (1004 aa)
