STRINGSTRING
PFA3 protein (Saccharomyces cerevisiae) - STRING interaction network
"PFA3" - Palmitoyltransferase for Vac8p, required for vacuolar membrane fusion 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

PFA3Palmitoyltransferase for Vac8p, required for vacuolar membrane fusion; contains an Asp-His-His-Cys-cysteine rich (DHHC-CRD) domain; autoacylates; required for vacuolar integrity under stress conditions; Palmitoyltransferase specific for VAC8. Palmitoylates VAC8 at one or more of its N-terminal cysteine residues, which is required for its proper membrane localization (336 aa)    
Predicted Functional Partners:
VAC8
Phosphorylated and palmitoylated vacuolar membrane protein; interacts with Atg13p, required for the cytoplasm-to-vacuole targeting (Cvt) pathway; interacts with Nvj1p to form nucleus-vacuole junctions; Functions in both vacuole inheritance and protein targeting from the cytoplasm to vacuole (578 aa)
     
 
  0.922
MEH1
Component of the EGO and GSE complexes; EGO is involved in the regulation of microautophagy and GSE is required for proper sorting of amino acid permease Gap1p; loss results in a defect in vacuolar acidification; Component of the GSE complex, a GTPase complex required for intracellular sorting of GAP1 out of the endosome. Component of the EGO complex, a complex involved in the regulation of microautophagy (184 aa)
       
 
  0.788
SHR5
Subunit of a palmitoyltransferase, composed of Shr5p and Erf2p, that adds a palmitoyl lipid moiety to heterolipidated substrates such as Ras1p and Ras2p through a thioester linkage; palmitoylation is required for Ras2p membrane localization; The ERF2-SHR5 complex is a palmitoyltransferase specific for Ras proteins. Palmitoylates RAS2, which is required for its proper plasma membrane localization (237 aa)
     
 
  0.762
AKR1
Palmitoyl transferase involved in protein palmitoylation; acts as a negative regulator of pheromone response pathway; required for endocytosis of pheromone receptors; involved in cell shape control; contains ankyrin repeats; Palmitoyltransferase specific for casein kinase 1. Palmitoylates isoforms YCK1 and YCK2 at both C-terminal cysteine residues, which is required for their proper plasma membrane localization. Required for constitutive endocytosis of a-factor receptor STE3 and both constitutive and pheromone-induced endocytosis of alpha-factor receptor STE2 (764 aa)
     
   
  0.737
AKR2
Ankyrin repeat-containing protein similar to Akr1p; member of a family of putative palmitoyltransferases containing an Asp-His-His-Cys-cysteine rich (DHHC-CRD) domain; possibly involved in constitutive endocytosis of Ste3p; May be involved in constitutive endocytosis of a-factor receptor STE3 (749 aa)
     
   
  0.711
YLR415C
Putative protein of unknown function; YLR415C is not an essential gene (112 aa)
           
  0.698
YKL165C-A
Dubious open reading frame unlikely to encode a protein, based on available experimental and comparative sequence data (77 aa)
           
  0.698
SQS1
Stimulates the ATPase and helicase activities of Prp43p; acts with Prp43p to stimulate 18s rRNA maturation by Nob1p; overexpression antagonizes the suppression of splicing defects by spp382 mutants; component of pre-ribosomal particles; May be involved in splicing since overexpression antagonizes the suppression of splicing defects by SPP382 mutants (767 aa)
           
  0.577
YCK3
Palmitoylated vacuolar membrane-localized casein kinase I isoform; negatively regulates vacuole fusion during hypertonic stress via phosphorylation of Vps41p; shares essential functions with Hrr25p; regulates vesicle fusion in AP-3 pathway; Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates (524 aa)
     
   
  0.554
RAS2
GTP-binding protein that regulates the nitrogen starvation response, sporulation, and filamentous growth; farnesylation and palmitoylation required for activity and localization to plasma membrane; homolog of mammalian Ras proto-oncogenes; The S.cerevisiae Ras proteins modulate the activity of the adenylate cyclase catalytic subunit and therefore affect the biosynthesis of cyclic-AMP (322 aa)
