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

Vps33BVacuolar protein sorting 33B (Vps33B) encodes a member of the family of SM proteins, which in conjunction with SNARE proteins catalyze membrane fusion events. The product of Vps33B, together with its binding partner encoded by Vps16B, forms a complex that is necessary for fusions between phagosomes and lysosomes; Belongs to the STXBP/unc-18/SEC1 family. (640 aa)    
Predicted Functional Partners:
Vps16A
Vacuolar protein sorting 16A (Vps16A) encodes a subunit of a heterohexameric tethering complex known as homotypic fusion and protein sorting (HOPS). HOPS roles include promoting the fusion of late endosomes, autophagosomes, biosynthetic vesicles, and lysosomes, and the biogenesis of lysosome-related eye pigment granules. The product of Vps16A is also part of miniCORVET (class C core vacuole/endosome tethering), a tethering complex involved in endosome maturation in nephrocytes and blood cells.

Vps16B
Vacuolar protein sorting 16B (Vps16B) encodes a protein that, together with its binding partner encoded by Vps33B, forms a distinct complex necessary for fusions between phagosomes and lysosomes.
   
 0.999
Vps11
Vacuolar protein sorting 11 (Vps11) encodes a Class C Vps core subunit of HOPS, a heterohexameric tethering complex that consists of the products of car, dor, lt, Vps11, Vps16A and Vps39. HOPS tethers autophagosomes or late endosomes with lysosomes to facilitate fusion. The product of Vps11 roles include autophagosome-lysosome fusion, late endosome-lysosome fusion and biosynthetic trafficking to lysosomes.

dor
Vacuolar protein sorting-associated protein 18 homolog; Plays a role in vesicle-mediated protein trafficking to lysosomal compartments and in membrane docking/fusion reactions of late endosomes/lysosomes probably as part of the class C core vacuole/endosome tethering (CORVET) complex. In larval neuromuscular junctions, essential for endosomal sorting which traffics old or dysfunctional synaptic vesicle proteins through a degradative endolysosomal route. Required for the biogenesis of eye pigment granules. Required to maintain normal levels of rush, which functions in endosome formation [...]

Vps39
Vacuolar protein sorting 39 (Vps39) encodes a subunit of the homotypic fusion and vacuole protein sorting (HOPS) complex required for autophagosome maturation.
   
 0.996
Vps8
Vacuolar protein sorting-associated protein 8 homolog; Plays a role in vesicle-mediated protein trafficking to lysosomal compartments and in membrane docking/fusion reactions of late endosomes/lysosomes probably as part of the class C core vacuole/endosome tethering (CORVET) complex. Specifically required for endocytic trafficking in a subset of cells, such as hemocytes and nephrocytes, which are highly active in endocytosis.
    
 0.993
lt
Vacuolar protein sorting-associated protein 41 homolog; Light (lt) encodes a cellular-protein trafficking protein that forms part of the homotypic fusion and vacuolar protein sorting (HOPS) and class C core vacuole/endosome tethering (CORVET) complexes. It is required for fusion of autophagosomes with lysosomes, endocytic down-regulation of Notch signaling, and eye pigment biogenesis; Belongs to the VPS41 family.
   
 0.992
Syx7
Syntaxin 7 (Syx7) encodes a SNARE protein that is part of the core machinery (including the products of Rab5, Rbsn-5, and Vps45) by which endocytic cargo vesicles fuse with the early endosome.
    
 
 0.959
Rab7
Rab7 (Rab7) encodes a small GTPase that contributes to vesicle trafficking regulation. It is involved in endosome maturation and fusion with lysosomes.
    
 
 0.953
Ccz1
Caffeine, calcium, zinc sensitivity 1 (Ccz1) encodes a protein that forms a complex with the product of Mon1 and acts as an exchange factor of the small G-protein encoded by Rab7. The Ccz1/Mon1 complex activates and recruits the product of Rab7 to the maturing endosome, where it organizes the fusion of the matured endosome with the lysosome. Ccz1/Mon1 complex loss of function results in Rab7 phenotypes.
