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

Tmtc3Protein O-mannosyl-transferase Tmtc3; Transfers mannosyl residues to the hydroxyl group of serine or threonine residues. (926 aa)    
Predicted Functional Partners:
PIG-B
GPI mannosyltransferase 3; Mannosyltransferase involved in glycosylphosphatidylinositol- anchor biosynthesis. Transfers the third alpha-1,2-mannose to Man2- GlcN-acyl-PI during GPI precursor assembly (By similarity). Belongs to the glycosyltransferase 22 family. PIGB subfamily.

rt
Protein O-mannosyltransferase 1; Rotated abdomen (rt) encodes a protein that transfers a mannose to the Ser/Thr residues of the product of Dg, via forming an heterodimer with the product of tw. Its roles include myogenesis, muscle architecture and cell adhesion.
   
  
 0.673
NANS
Sialic acid synthase; Produces N-acetylneuraminic acid (Neu5Ac) and 2-keto-3-deoxy- D-glycero-D-galacto-nononic acid (KDN). Can also use N-acetylmannosamine 6-phosphate and mannose 6-phosphate as substrates to generate phosphorylated forms of Neu5Ac and KDN, respectively. Essential for biosynthesis of sialic acids in neurons of the central nervous system.
     
 0.619
PIG-Z
GPI mannosyltransferase 4; Mannosyltransferase involved in glycosylphosphatidylinositol- anchor biosynthesis. Transfers a fourth mannose to some trimannosyl- GPIs during GPI precursor assembly (By similarity).

RpII140
DNA-directed RNA polymerase II subunit RPB2; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB2 is [...]

IntS1
Integrator complex subunit 1; Component of the Integrator complex, a complex involved in the transcription of small nuclear RNAs (snRNA) and their 3'-box- dependent processing. Involved in the 3'-end processing of the U7 snRNA, and also the spliceosomal snRNAs U1, U2, U4 and U5. Required for the normal expression of the Integrator complex component IntS12. May mediate recruitment of cytoplasmic dynein to the nuclear envelope, probably as component of the INT complex (By similarity).

asun
Protein asunder; Component of the Integrator complex, a complex involved in the transcription of small nuclear RNAs (snRNA) and their 3'-box- dependent processing. Involved in the 3'-end processing of the U7 snRNA, and also the spliceosomal snRNAs U1 and U5. Plays a role as a regulator of spermatogenesis. Crucial regulator of the mitotic cell cycle and development. Required for the correct dynein-dynactin perinuclear localization important for nucleus- centrosome coupling that occur upon meiotic progression of primary spermatocytes. Plays a role in sperm motility and fertility. May hav [...]

tw
Protein O-mannosyl-transferase 2; Twisted (tw) encodes a protein that transfers a mannose to the Ser/Thr residues of dystroglycan, via forming an heterodimer with the product of rt. Its roles include myogenesis, muscle architecture and cell adhesion.
