STRINGSTRING
PSS1 protein (Arabidopsis thaliana) - STRING interaction network
"PSS1" - Phosphatidylserine synthase 1 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

PSS1Phosphatidylserine synthase 1; Catalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine (PE) or phosphatidylcholine (PC) is replaced by L-serine. Is essential for phosphatidylserine (PS) biosynthesis and PE seems to be the most plausible substrate. Plays an important role in microspore maturation (453 aa)    
Predicted Functional Partners:
PLDP2
Phospholipase D P2; Hydrolyzes glycerol-phospholipids at the terminal phosphodiesteric bond to generate phosphatidic acids (PA). Phosphatidylcholine-selective (PubMed-11891260). Regulates vesicle trafficking and auxin responses (PubMed-17259265). Required for the normal cycling of PIN-2 containing vesicles (PubMed-17259265). Contributes to the supply of inorganic phosphorus for cell metabolism and diacylglycerol moieties for galactolipid synthesis in phosphorus-starved roots (PubMed-16891548, PubMed-16617110). Involved in root elongation during phosphate limitation (PubMed-16384909) (1046 aa)

AAPT1
Ethanolaminephosphotransferase; Catalyzes both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP- ethanolamine, respectively. Has a higher cholinephosphotransferase activity than ethanolaminephosphotransferase activity (389 aa)

PLDALPHA1
Phospholipase D alpha 1; Hydrolyzes glycerol-phospholipids at the terminal phosphodiesteric bond to generate phosphatidic acids (PA). Plays an important role in various cellular processes, including phytohormone action and response to stress, characterized by acidification of the cell (PubMed-9437863). Involved in wound induction of jasmonic acid (PubMed-11090221). May be involved in membrane lipid remodeling (PubMed-11239826).
