STRINGSTRING
PSS1 protein (Arabidopsis thaliana) - STRING interaction network
"PSS1" - CDP-diacylglycerol--serine O-phosphatidyltransferase 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

PSS1CDP-diacylglycerol--serine O-phosphatidyltransferase 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; Belongs to the CDP-alcohol phosphatidyltransferase class-I family (453 aa)    
Predicted Functional Partners:
AAPT2
Choline/ethanolaminephosphotransferase 2; Catalyzes both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP- ethanolamine, respectively. Has a higher cholinephosphotransferase activity than ethanolaminephosphotransferase activity; Belongs to the CDP-alcohol phosphatidyltransferase class-I family (389 aa)
     
 
  0.962
AAPT1
Choline/ethanolaminephosphotransferase 1; Catalyzes both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP- ethanolamine, respectively. Has a higher cholinephosphotransferase activity than ethanolaminephosphotransferase activity; Belongs to the CDP-alcohol phosphatidyltransferase class-I family (389 aa)
         
  0.961
PSD1
Phosphatidylserine decarboxylase proenzyme 1, mitochondrial; Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer). Plays a central role in phospholipid metabolism and in the interorganelle trafficking of phosphatidylserine. Contributes only to a minor proportion of PtdEtn production; Belongs to the phosphatidylserine decarboxylase family. PSD-B subfamily. Eukaryotic type I sub-subfamily (453 aa)
     
 
  0.948
LCAT3
Lecithin-cholesterol acyltransferase 3; Hydrolyzes the sn-1 acylester bond of phospholipids. Phosphatidylcholine, phosphatidylethanolamine and phosphatidic acid can be used as substrates. Weak activity with lysophosphatidylcholine and no activity with tripalmitoylglycerol and cholesteryl oleate. Seems to have a preference for unsaturated fatty acids at the sn-1 position (447 aa)
     
 
  0.923
SDP1
Patatin-like phospholipase family protein; Involved in the release of fatty acids from the oil body in germinating seedlings. Could hydrolyze triacylglycerols and diacylglycerols but not monoacylglycerols, phospholipids, galactolipids or cholesterol esters (825 aa)
         
  0.919
SDP1-LIKE
Triacylglycerol lipase SDP1L; May be involved in the release of fatty acids from the oil body in germinating seedlings. Can hydrolyze triacylglycerols in vitro (801 aa)
         
  0.919
AT4G19860
Lecithin-cholesterol acyltransferase-like 4; alpha/beta-Hydrolases superfamily protein; Its function is described as phosphatidylcholine-sterol O-acyltransferase activity; Involved in lipid metabolic process; Located in cellular_component unknown; Expressed in 23 plant structures; Expressed during 15 growth stages; Contains the following InterPro domains- Lecithin-cholesterol acyltransferase (InterPro-IPR003386); BEST Arabidopsis thaliana protein match is- lecithin-cholesterol acyltransferase 3 (TAIR-AT3G03310.1); Has 596 Blast hits to 589 proteins in 168 species- Archae - 2; Bacteria [...] (535 aa)

NPC3
Non-specific phospholipase C3; Possesses specific phosphatase activity toward lysophosphatidic acid (LPA) in vitro. Does not show phospholipase C activity. May play a role in signal transduction and storage lipid synthesis. May be involved in brassinolide-mediated signaling in root development (523 aa)
     
 
    0.901
NPC4
Non-specific phospholipase C4; Non-specific phospholipase C (PLC) which assumes major PLC activity during inorganic phosphate starvation. Substrate preference is phosphatidylcholine (PC), but can also hydrolyze phosphatidylethanolamine (PE) with lower efficiency. Has no activity toward phosphatidic acid (PA). Plays an important role in the supply of both inorganic phosphate and diacylglycerol from membrane-localized phospholipids during phosphate deprivation. May be required for lipid-derived signaling molecules that positively modulate abscisic acid (ABA) response and promote plant to [...] (538 aa)

LPLAT2
MBOAT (membrane bound O-acyl transferase) family protein; Lysophospholipid acyltransferase with broad specificity. Mediates the conversion of lysophosphatidylethanolamine (1-acyl- sn-glycero-3-phosphoethanolamine or LPE) into phosphatidylethanolamine (1,2-diacyl-sn-glycero-3- phosphoethanolamine or PE) (LPEAT activity). Catalyzes the acylation of lysophosphatidylserine (1-acyl-2-hydroxy-sn-glycero- 3-phospho-L-serine or LPS) into phosphatidylserine (1,2-diacyl-sn- glycero-3-phospho-L-serine or PS) (LPSAT activity). Can convert lysophosphatidylcholine (1-acyl-sn-glycero-3-phosphocholine [...] (465 aa)
