"CPTP" - Ceramide-1-phosphate transfer protein 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

CPTPCeramide-1-phosphate transfer protein; Mediates the intracellular transfer of ceramide-1- phosphate between organelle membranes and the cell membrane. Required for normal structure of the Golgi stacks. Can bind phosphoceramides with a variety of aliphatic chains, but has a preference for lipids with saturated C16-0 or monounsaturated C18-1 aliphatic chains, and is inefficient with phosphoceramides containing lignoceryl (C24-0). Plays a role in the regulation of the cellular levels of ceramide-1-phosphate, and thereby contributes to the regulation of phospholipase PLA2G4A activity and t [...] (214 aa)    
Predicted Functional Partners:
ACPT
Testicular acid phosphatase; May dephosphorylate receptor tyrosine-protein kinase ERBB4 and inhibits its ligand-induced proteolytic cleavage. May play a role in odontogenesis (426 aa)
           
  0.708
CERK
Ceramide kinase; Catalyzes specifically the phosphorylation of ceramide to form ceramide 1-phosphate. Acts efficiently on natural and analog ceramides (C6, C8, C16 ceramides, and C8-dihydroceramide), to a lesser extent on C2-ceramide and C6-dihydroceramide, but not on other lipids, such as various sphingosines. Binds phosphoinositides (537 aa)
           
  0.643
GLTP
Glycolipid transfer protein; Accelerates the intermembrane transfer of various glycolipids. Catalyzes the transfer of various glycosphingolipids between membranes but does not catalyze the transfer of phospholipids. May be involved in the intracellular translocation of glucosylceramides (209 aa)
     
   
  0.619
ACER1
Alkaline ceramidase 1; Hydrolyzes the sphingolipid ceramide into sphingosine and free fatty acid at an optimal pH of 8.0. Has a highly restricted substrate specificity for the natural stereoisomer of ceramide with D-erythro-sphingosine but not D-ribo- phytosphingosine or D-erythro-dihydrosphingosine as a backbone. May have a role in regulating the levels of bioactive lipids ceramide and sphingosine 1-phosphate, as well as complex sphingolipids (By similarity); Alkaline ceramidases (264 aa)
           
  0.547
CKAP4
Cytoskeleton-associated protein 4; High-affinity epithelial cell surface receptor for APF (602 aa)
           
  0.494
DFFB
DNA fragmentation factor subunit beta; Nuclease that induces DNA fragmentation and chromatin condensation during apoptosis. Degrades naked DNA and induces apoptotic morphology (362 aa)
           
  0.475
WBSCR27
Methyltransferase-like protein 27; Williams Beuren syndrome chromosome region 27 (245 aa)
     
   
  0.464
PIK3IP1
Phosphoinositide-3-kinase-interacting protein 1; Negative regulator of hepatic phosphatidylinositol 3- kinase (PI3K) activity (263 aa)
           
  0.459
RERE
Arginine-glutamic acid dipeptide repeats protein; Plays a role as a transcriptional repressor during development. May play a role in the control of cell survival. Overexpression of RERE recruits BAX to the nucleus particularly to POD and triggers caspase-3 activation, leading to cell death; GATA zinc finger domain containing (1566 aa)
           
  0.458
LOC646862
RING finger protein 225; Uncharacterized protein LOC646862 (329 aa)
           
  0.453
