"PTAC4" - Plastid transcriptionally active 4 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

PTAC4Plastid transcriptionally active 4; Required for plastid vesicle formation and thylakoid membrane biogenesis, but not for functional assembly of thylakoid protein complexes (330 aa)    
Predicted Functional Partners:
ALB3
ALBINO 3; Required for the insertion of some light harvesting chlorophyll-binding proteins (LHCP) into the chloroplast thylakoid membrane. Required for the insertion of LHCB1, LHCB4.1 and LHCB5 proteins into thylakoid membrane, while it is not required for insertion of proteins PsbX, PsbW and PsbY (462 aa)
     
 
  0.883
PSB29
Protein THYLAKOID FORMATION 1; Involved in a dynamic process of vesicle-mediated thylakoid membrane biogenesis. Required for the normal organization of vesicles into mature thylakoid stacks and ultimately for leaf development. Also involved in a sugar- signaling mechanism in roots by mediating signaling between the plasma membrane and the plastid. Probably acts downstream of the plasma membrane-delimited heterotrimeric G-protein GPA1 in a D- glucose signaling pathway (300 aa)
   
   
  0.805
CR88
Chaperone protein htpG family protein; Molecular chaperone required for chloroplast biogenesis (PubMed-12943545, PubMed-25216779). Essential for chloroplast biogenesis and maintenance, and thus for embryogenesis (PubMed-23875936, PubMed-23382192). May be involved in the disassembly of VIPP1 for thylakoid membrane formation and/or maintenance (PubMed-23875936). Cooperates with TIC components and other molecular chaperones to drive transport of preproteins into chloroplasts and functions in the chloroplast stroma to facilitate membrane translocation during protein import into the organel [...] (780 aa)
     
 
  0.800
ALB4
ALBINA 4; Probably required for the insertion of integral membrane proteins into the chloroplast thylakoid membranes (499 aa)
     
 
  0.714
AT1G51110
Putative plastid-lipid-associated protein 12 (409 aa)
     
   
  0.698
AT5G03880
Thioredoxin family protein (339 aa)
     
        0.698
HCF136
HIGH CHLOROPHYLL FLUORESCENCE 136; Essential for photosystem II (PSII) biogenesis; required for assembly of an early intermediate in PSII assembly that includes D2 (psbD) and cytochrome b559. Has been suggested (PubMed-11826309) to be required for chlorophyll a binding (403 aa)
     
   
  0.679
APE1
Mutant has Altered acclimation responses; (431 aa)
     
   
  0.677
cpHsc70-2
Heat shock protein 70-2; Acts redundantly with HSP70-6 in the thermotolerance of germinating seeds. Plays an important role in the protein precursor import into chloroplasts (718 aa)
     
   
  0.670
AT5G52580
RabGAP/TBC domain-containing protein (690 aa)
