STRINGSTRING
YPT6 protein (Saccharomyces cerevisiae) - STRING interaction network
"YPT6" - Rab family GTPase, Ras-like GTP binding protein involved in the secretory pathway, required for fusion of endosome-derived vesicles with the late Golgi, maturation of the vacuolar carboxypeptidase Y in Saccharomyces cerevisiae
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

YPT6Rab family GTPase, Ras-like GTP binding protein involved in the secretory pathway, required for fusion of endosome-derived vesicles with the late Golgi, maturation of the vacuolar carboxypeptidase Y; has similarity to the human GTPase, Rab6; Protein transport. Might participate in post-Golgi transport (215 aa)    
Predicted Functional Partners:
VPS52
Component of the GARP (Golgi-associated retrograde protein) complex, Vps51p-Vps52p-Vps53p-Vps54p, which is required for the recycling of proteins from endosomes to the late Golgi; involved in localization of actin and chitin; Involved in retrograde transport from early and late endosomes to late Golgi by linking the vesicle through the t-SNARE TGL1 to the Golgi, leading to the membrane fusion between late Golgi and endosomal vesicles. May also be involved in the actin cytoskeleton organization (641 aa)
     
 
  0.985
GDI1
GDP dissociation inhibitor, regulates vesicle traffic in secretory pathways by regulating the dissociation of GDP from the Sec4/Ypt/rab family of GTP binding proteins; Regulates the GDP/GTP exchange reaction of SEC4 by inhibiting the dissociation of GDP from it, and the subsequent binding of GTP to SEC4. Plays an essential role in the yeast secretory pathway (451 aa)
     
 
  0.985
MRS6
Rab escort protein, forms a complex with the Ras-like small GTPase Ypt1p that is required for the prenylation of Ypt1p by protein geranylgeranyltransferase type II (Bet2p-Bet4p); sequence similarity to mammalian choroideraemia gene; Substrate-binding subunit (component A) of the Rab geranylgeranyltransferase (GGTase) complex. Binds unprenylated Rab proteins and presents the substrate peptide to the catalytic component B. The component A is thought to be regenerated by transferring its prenylated Rab back to the donor membrane (603 aa)
     
 
  0.970
RGP1
Subunit of a Golgi membrane exchange factor (Ric1p-Rgp1p) that catalyzes nucleotide exchange on Ypt6p; The RIC1-RGP1 complex acts as a guanine nucleotide exchange factor (GEF), which activates YPT6 by exchanging bound GDP for free GTP. It is thereby required for efficient fusion of endosome-derived vesicles with the Golgi. The RIC1-RGP1 participates in the recycling of SNC1, presumably by mediating fusion of endosomal vesicles with the Golgi compartment (663 aa)
       
 
  0.967
VPS63
Dubious open reading frame, unlikely to encode a protein; not conserved in closely related Saccharomyces species; 98% of ORF overlaps the verified gene YPT6; deletion causes a vacuolar protein sorting defect (108 aa)
     
   
  0.954
RIC1
Protein involved in retrograde transport to the cis-Golgi network; forms heterodimer with Rgp1p that acts as a GTP exchange factor for Ypt6p; involved in transcription of rRNA and ribosomal protein genes; The RIC1-RGP1 complex acts as a guanine nucleotide exchange factor (GEF), which activates YPT6 by exchanging bound GDP for free GTP. It is thereby required for efficient fusion of endosome-derived vesicles with the Golgi. The RIC1-RGP1 participates in the recycling of SNC1, presumably by mediating fusion of endosomal vesicles with the Golgi compartment. May also be indirectly involved [...] (1056 aa)

ARL1
Soluble GTPase with a role in regulation of membrane traffic; regulates potassium influx; G protein of the Ras superfamily, similar to ADP-ribosylation factor; Recruits golgins such as IMH1 to the Golgi. Can bind and hydrolyze GTP. May be involved in trafficking events within the endosomal system (183 aa)

VPS53
Component of the GARP (Golgi-associated retrograde protein) complex, Vps51p-Vps52p-Vps53p-Vps54p, which is required for the recycling of proteins from endosomes to the late Golgi; required for vacuolar protein sorting; Involved in retrograde transport from early and late endosomes to late Golgi by linking the vesicle through the t-SNARE TGL1 to the Golgi, leading to the membrane fusion between late Golgi and endosomal vesicles (822 aa)
       
 
  0.925
VPS54
Component of the GARP (Golgi-associated retrograde protein) complex, Vps51p-Vps52p-Vps53p-Vps54p, which is required for the recycling of proteins from endosomes to the late Golgi; potentially phosphorylated by Cdc28p; Involved in retrograde transport from early and late endosomes to late Golgi by linking the vesicle through the t-SNARE TGL1 to the Golgi, leading to the membrane fusion between late Golgi and endosomal vesicles. Seems also to be involved in protein transport from Golgi to the plasma membrane and is required for the integrity of the actin cytoskeleton (889 aa)
       
 
  0.898
IMH1
Protein involved in vesicular transport, mediates transport between an endosomal compartment and the Golgi, contains a Golgi-localization (GRIP) domain that interacts with activated Arl1p-GTP to localize Imh1p to the Golgi; Involved in vesicular transport between an endosomal compartment and the Golgi apparatus (911 aa)
