STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SMSrSphingomyelin synthase-related 1; Sphingomyelin synthases synthesize sphingolipids through transfer of a phosphatidyl head group on to the primary hydroxyl of ceramide. SAMD8 is an endoplasmic reticulum (ER) transferase that has no sphingomyelin synthase activity but can convert phosphatidylethanolamine (PE) and ceramide to ceramide phosphoethanolamine (CPE) albeit with low product yield. Appears to operate as a ceramide sensor to control ceramide homeostasis in the endoplasmic reticulum rather than a converter of ceramides. Seems to be critical for the integrity of the early secretory [...] (600 aa)    
Predicted Functional Partners:
Spt-I
Pyridoxal phosphate binding; serine C-palmitoyltransferase activity. It is involved in the biological process described with: positive regulation of sphingolipid biosynthetic process; ceramide biosynthetic process; sphingosine biosynthetic process.
      
 0.852
lace
Lace, isoform A; Lace (lace) encodes a serine C-palmitoyltransferase involved in sphingolipid biosynthesis.
   
  
 0.829
Cerk
Ceramide kinase (Cerk) encodes a protein that catalyzes phosphorylation of ceramide, helping to maintain ceramide levels, which in turn regulates photoreceptor structure and function. It is also a component of WntD signaling and mediates primordial germ cell migration.
