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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
MTERF1Transcription termination factor MTEF1, chloroplastic; Transcription termination factor required for plastid- specific rRNA accumulation and protein synthesis in plastids. Essential for embryogenesis. (284 aa)
HO1Heme oxygenase 1, chloroplastic; Key enzyme in the synthesis of the chromophore of the phytochrome family of plant photoreceptors. Catalyzes the opening of the heme ring to form the open-chain tetrapyrrole biliverdin IX with the release of iron and carbon monoxide (CO). Produces specifically the biliverdin IX-alpha isomer. Can form complex with heme, is ferredoxin- dependent and its activity is increased in the presence of ascorbate. Plays a role in salt acclimation signaling. May affect the plastid-to- nucleus signaling pathway by perturbing tetrapyrrole synthesis. The plastid-to-nucl [...] (282 aa)
PHOT2Phototropin-2; Protein kinase that acts as a blue light photoreceptor in a signal-transduction pathway for photo-induced movements. Phosphorylates BLUS1, a kinase involved in stomatal opening. Mediates calcium spiking of extra- and intracellular origins in response to blue light. Involved in hypocotyl phototropism. Contributes to the chloroplast accumulation in low blue light and mediates their translocation (avoidance response) at high fluence. Regulates stomata opening and photomorphogenesis response of leaf tissue. Not involved in hypocotyl elongation inhibition, anthocyanin accumul [...] (915 aa)
PDS15-cis-phytoene desaturase, chloroplastic/chromoplastic; Converts phytoene into zeta-carotene via the intermediary of phytofluene by the symmetrical introduction of two double bonds at the C-11 and C-11' positions of phytoene with a concomitant isomerization of two neighboring double bonds at the C9 and C9' positions from trans to cis; Belongs to the carotenoid/retinoid oxidoreductase family. (566 aa)
FER1Ferritin-1, chloroplastic; Stores iron in a soluble, non-toxic, readily available form. Important for iron homeostasis. Has ferroxidase activity. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation (By similarity). (255 aa)
ZAT12Zinc finger protein ZAT12; Transcriptional repressor involved in light acclimation, cold and oxidative stress responses. May regulate a collection of transcripts involved in response to high-light, cold and oxidative stress. (162 aa)
FTSZ1Cell division protein FtsZ homolog 1, chloroplastic; Exhibits GTPase activity. Component of the plastid division machinery that forms a contractile ring at the division site. Required for plastid division in a dose-dependent manner. Involved in blue light-induced chloroplast movements. May regulate thylakoid development. Belongs to the FtsZ family. (433 aa)
BHLH137Transcription factor bHLH137. (286 aa)
EX1Protein EXECUTER 1, chloroplastic; Together with EX2, enables higher plants to perceive singlet oxygen as a stress signal in plastid that activates a genetically determined nuclear stress response program which triggers a programmed cell death (PCD). This transfer of singlet oxygen-induced stress- related signals from the plastid to the nucleus that triggers genetically controlled PCD pathway is unique to photosynthetic eukaryotes and operates under mild stress conditions, impeding photosystem II (PSII) without causing photooxidative damage of the plant. (684 aa)
BAP1BON1-associated protein 1; Negative regulator of cell death and defense responses. Exhibits calcium-dependent phospholipid binding properties. (192 aa)
EX2Protein EXECUTER 2, chloroplastic; Together with EX1, enables higher plants to perceive singlet oxygen as a stress signal in plastid that activates a genetically determined nuclear stress response program which triggers a programmed cell death (PCD). This transfer of singlet oxygen-induced stress- related signals from the plastid to the nucleus that triggers genetically controlled PCD pathway is unique to photosynthetic eukaryotes and operates under mild stress conditions, impeding photosystem II (PSII) without causing photooxidative damage of the plant. (651 aa)
MINE1Cell division topological specificity factor homolog, chloroplastic; Acts as a topological specificity factor during plastid division and specify plastid constriction sites. May contribute to gravitropism in stems and hypocotyls. Stimulates MIND1 ATPase activity. In cooperation with MIND1, prevents FtsZ ring formation anywhere outside of the mid-plastids. Belongs to the MinE family. (229 aa)
CRLChromophore lyase CRL, chloroplastic; Covalently attaches a chromophore to Cys residue(s) of phycobiliproteins (By similarity). Required for plastid division, and involved in cell differentiation and regulation of the cell division plane. Maintenance of plastid homeostasis controls plant preconditioning to stress and stress acclimation. Belongs to the CpcT/CpeT biliprotein lyase family. (269 aa)
ARC6Protein ACCUMULATION AND REPLICATION OF CHLOROPLASTS 6, chloroplastic; Component of the plastid division machinery. Involved in the initiation of proplastid and plastid division (including chloroplasts, statoliths and leukoplasts). Promotes the assembly and/or stabilization of the plastid-dividing FtsZ ring, functioning as an antagonistic regulator of FtsZ dynamics against CDP1. Relays plastid division site position between stroma and outer surface via interactions with the stromal FtsZ ring and the outer membrane PDV2 that recruits cytoplasmic ARC5 ring. Required for plastid equatoria [...] (801 aa)
SIGFRNA polymerase sigma factor sigF, chloroplastic; Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released. Regulates transcription in chloroplast in a DG1-dependent manner. Involved in light-dependent chloroplast development. Required during early plant development and primary leaf formation. (547 aa)
CHUP1Protein CHUP1, chloroplastic; 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)
MZN14.5AAA-ATPase At3g28580; Belongs to the AAA ATPase family. BCS1 subfamily. (500 aa)
