STRINGSTRING
APE4 protein (Saccharomyces cerevisiae) - STRING interaction network
"APE4" - Cytoplasmic aspartyl aminopeptidase with possible vacuole function 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

APE4Cytoplasmic aspartyl aminopeptidase with possible vacuole function; Cvt pathway cargo protein; cleaves unblocked N-terminal acidic amino acids from peptide substrates; forms a 12-subunit homo-oligomer; M18 metalloprotease family; Aspartyl aminopeptidase that contributes to peptide degradation both in the cytosol and the vacuole. Cells may respond to environmental conditions by changing the distributions of the cytosolic enzyme to the vacuole when cells need more active vacuolar degradation (490 aa)    
Predicted Functional Partners:
ATG19
Receptor protein specific for the cytoplasm-to-vacuole targeting (Cvt) pathway; delivers cargo proteins aminopeptidase I (Lap4p) and alpha-mannosidase (Ams1p) to the phagophore assembly site for packaging into Cvt vesicles; Cargo-receptor protein involved in the cytoplasm to vacuole transport (Cvt) and in autophagy. Recognizes cargo proteins, such as APE4, LAP3, LAP4 and AMS1 and delivers them to the pre-autophagosomal structure for eventual engulfment by the autophagosome and targeting to the vacuole. Involved in the organization of the preautophagosomal structure (PAS). ATG19 associa [...] (415 aa)

ICP55
Mitochondrial aminopeptidase; cleaves the N termini of at least 38 imported proteins after cleavage by the mitochondrial processing peptidase (MPP), thereby increasing their stability; member of the aminopeptidase P family; Aminopeptidase which cleaves preprotein intermediates that carry destabilizing N-ter amino acid residues after the mitochondrial processing peptidase (MPP) cleavage site and is thus critical for stabilization of the mitochondrial proteome (511 aa)
   
   
  0.665
ATG34
Receptor protein involved in selective autophagy during starvation; specifically involved in the transport of cargo protein alpha-mannosidase (Ams1p); Atg19p paralog; Cargo-receptor protein involved in the cytoplasm to vacuole transport (Cvt) and in autophagy. Recognizes cargo proteins, such as AMS1 and delivers them to the pre-autophagosomal structure for eventual engulfment by the autophagosome and targeting to the vacuole (412 aa)
       
 
  0.653
CIT1
Citrate synthase, catalyzes the condensation of acetyl coenzyme A and oxaloacetate to form citrate; the rate-limiting enzyme of the TCA cycle; nuclear encoded mitochondrial protein; Specific citrate synthase with catalytic activity only with acetyl-CoA (479 aa)
       
 
  0.593
AMS1
Vacuolar alpha mannosidase, involved in free oligosaccharide (fOS) degradation; delivered to the vacuole in a novel pathway separate from the secretory pathway; Degrades free oligosaccharides in the vacuole (1083 aa)
     
   
  0.584
CIT3
Dual specificity mitochondrial citrate and methylcitrate synthase; catalyzes the condensation of acetyl-CoA and oxaloacetate to form citrate and that of propionyl-CoA and oxaloacetate to form 2-methylcitrate; Dual specificity mitochondrial citrate and methylcitrate synthase with similar catalytic efficiency with both acetyl-CoA and propionyl-CoA (486 aa)
       
      0.543
ATG11
Adapter protein for pexophagy and the cytoplasm-to-vacuole targeting (Cvt) pathway; directs receptor-bound cargo to the phagophore assembly site (PAS) for packaging into vesicles; required for recruiting other proteins to the (PAS); Involved in cytoplasm to vacuole transport (Cvt), pexophagy, mitophagy and nucleophagy. Recruits mitochondria for their selective degradation via autophagy (mitophagy) during starvation, through its interaction with ATG32. Works as scaffold proteins that recruit ATG proteins to the pre-autophagosome (PAS), the site of vesicle/autophagosome formation. Requir [...] (1178 aa)

LAP2
Leucyl aminopeptidase yscIV (leukotriene A4 hydrolase) with epoxide hydrolase activity, metalloenzyme containing one zinc atom; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm and nucleus; Aminopeptidase that preferentially cleaves tripeptides. Also has low epoxide hydrolase activity (in vitro). Can hydrolyze an epoxide moiety of LTA(4) to form LTB(4) (in vitro) (671 aa)
