"PLB1" - Phospholipase B1, membrane-associated in Homo sapiens
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

PLB1Phospholipase B1, membrane-associated; Membrane-associated phospholipase. Exhibits a calcium- independent broad substrate specificity including phospholipase A2/lysophospholipase activity. Preferential hydrolysis at the sn-2 position of diacylphospholipids and diacyglycerol, whereas it shows no positional specificity toward triacylglycerol. Exhibits also esterase activity toward p-nitrophenyl. May act on the brush border membrane to facilitate the absorption of digested lipids (By similarity); Phospholipases (1458 aa)    
Predicted Functional Partners:
LCAT
Phosphatidylcholine-sterol acyltransferase; Central enzyme in the extracellular metabolism of plasma lipoproteins. Synthesized mainly in the liver and secreted into plasma where it converts cholesterol and phosphatidylcholines (lecithins) to cholesteryl esters and lysophosphatidylcholines on the surface of high and low density lipoproteins (HDLs and LDLs). The cholesterol ester is then transported back to the liver. Has a preference for plasma 16-0-18-2 or 18-O-18-2 phosphatidylcholines. Also produced in the brain by primary astrocytes, and esterifies free cholesterol on nascent APOE- [...] (440 aa)

PLA2G16
HRAS-like suppressor 3; Lipid-modifying enzyme that acts as major regulator of adipocyte lipolysis by catalyzing the release of fatty acids from phospholipids in adipose tissue. Shows phospholipase A1 and A2 activity, catalyzing the calcium- independent hydrolysis of acyl groups in various phosphatidylcholines (PC) and phosphatidylethanolamine (PE). For most substrates, phospholipase A1 activity is much higher than phospholipase A2 activity. Phospholipase activity causes decreased intracellular levels of ether-type lipids, affecting peroxisome metabolism (By similarity). May also have [...] (162 aa)

GPCPD1
Glycerophosphocholine phosphodiesterase GPCPD1; May be involved in the negative regulation of skeletal muscle differentiation, independently of its glycerophosphocholine phosphodiesterase activity; Belongs to the glycerophosphoryl diester phosphodiesterase family (672 aa)
         
    0.900
LYPLA1
Acyl-protein thioesterase 1; Hydrolyzes fatty acids from S-acylated cysteine residues in proteins such as trimeric G alpha proteins or HRAS. Has depalmitoylating activity toward KCNMA1. Has low lysophospholipase activity; Belongs to the AB hydrolase superfamily. AB hydrolase 2 family (230 aa)
     
 
  0.869
PNPLA6
Neuropathy target esterase; Phospholipase B that deacylates intracellular phosphatidylcholine (PtdCho), generating glycerophosphocholine (GroPtdCho). This deacylation occurs at both sn-2 and sn-1 positions of PtdCho. Its specific chemical modification by certain organophosphorus (OP) compounds leads to distal axonopathy; Patatin like phospholipase domain containing (1375 aa)
         
  0.841
LYPLA2
Acyl-protein thioesterase 2; Hydrolyzes fatty acids from S-acylated cysteine residues in proteins such as trimeric G alpha proteins, GAP43, ZDHHC6 or HRAS. Deacylates GAP43. Mediates depalmitoylation of ZDHHC6. Has lysophospholipase activity (By similarity) (231 aa)
     
 
  0.841
PLA2G15
Group XV phospholipase A2; Has transacylase and calcium-independent phospholipase A2 activity. Catalyzes the formation of 1-O-acyl-N-acetylsphingosine and the concomitant release of a lyso-phospholipid. Has high activity with 1-palmitoyl-2-oleoyl-sn-glycero-3- phosphocholine (POPC) and 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), catalyzing the transfer of oleic acid to N-acetyl- sphingosine. Required for normal phospholipid degradation in alveolar and peritoneal macrophages and in spleen (By similarity). May have weak lysophospholipase activity; Phospholipases (412 aa)
         
  0.821
PNPLA7
Patatin-like phospholipase domain-containing protein 7; Serine hydrolase, whose specific chemical modification by certain organophosphorus (OP) compounds leads to distal axonopathy; Patatin like phospholipase domain containing (1342 aa)
     
 
  0.817
PLA2G2E
Group IIE secretory phospholipase A2; PA2 catalyzes the calcium-dependent hydrolysis of the 2- acyl groups in 3-sn-phosphoglycerides. Has a preference for arachidonic-containing phospholipids; Phospholipases (142 aa)
         
  0.780
CEPT1
Choline/ethanolaminephosphotransferase 1; Catalyzes both phosphatidylcholine and phosphatidylethanolamine biosynthesis from CDP-choline and CDP- ethanolamine, respectively. Involved in protein-dependent process of phospholipid transport to distribute phosphatidyl choline to the lumenal surface. Has a higher cholinephosphotransferase activity than ethanolaminephosphotransferase activity; Belongs to the CDP-alcohol phosphatidyltransferase class-I family (416 aa)
