STRINGSTRING
PAA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PAA1" - Polyamine acetyltransferase 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

PAA1Polyamine acetyltransferase; acetylates polyamines (e.g. putrescine, spermidine, spermine) and also aralkylamines (e.g. tryptamine, phenylethylamine); may be involved in transcription and/or DNA replication; Acetylates spermine and probably also other polyamines such as putrescine or spermidine. May regulate the levels of polyamines on chromosomal DNA, which would modify chromatin structure and affect transcription or replication. Also able to acetylate arylalkylamines such as tryptamine and serotonin in vitro (191 aa)    
Predicted Functional Partners:
ALD6
Cytosolic aldehyde dehydrogenase, activated by Mg2+ and utilizes NADP+ as the preferred coenzyme; required for conversion of acetaldehyde to acetate; constitutively expressed; locates to the mitochondrial outer surface upon oxidative stress; Cytosolic aldehyde dehydrogenase which utilizes NADP+ as the preferred coenzyme. Performs the conversion of acetaldehyde to acetate (500 aa)

PTC2
Type 2C protein phosphatase (PP2C); dephosphorylates Hog1p to limit maximal osmostress induced kinase activity; dephosphorylates Ire1p to downregulate the unfolded protein response; dephosphorylates Cdc28p; inactivates the DNA damage checkpoint; Responsible, together with PTC3, for the dephosphorylation of the cyclin-dependent protein kinase CDC28 (464 aa)
       
 
  0.870
PTC4
Cytoplasmic type 2C protein phosphatase (PP2C); identified as a high-copy number suppressor of cnb1 mpk1 synthetic lethality; overexpression decreases high-osmolarity induced Hog1p phosphorylation and kinase activity (393 aa)
       
 
  0.870
PTC3
Type 2C protein phosphatase (PP2C); dephosphorylates Hog1p (see also Ptc2p) to limit maximal kinase activity induced by osmotic stress; dephosphorylates T169 phosphorylated Cdc28p (see also Ptc2p); role in DNA damage checkpoint inactivation; Responsible, together with PTC2, for the dephosphorylation of the cyclin-dependent protein kinase CDC28 (468 aa)
       
 
  0.870
SSS1
Subunit of the Sec61p translocation complex (Sec61p-Sss1p-Sbh1p) that forms a channel for passage of secretory proteins through the endoplasmic reticulum membrane, and of the Ssh1p complex (Ssh1p-Sbh2p-Sss1p); interacts with Ost4p and Wbp1p; Part of the Sec61 complex, which is the major component of channel-forming translocon complex that mediates protein translocation across the endoplasmic reticulum (ER). The functional states of the translocon complex include co- and post- translational ER import, cotranslational membrane protein integration and retrograde transport of misfolded pro [...] (80 aa)
     
        0.867
OCA6
Cytoplasmic protein required for replication of Brome mosaic virus; S. cerevisiae is a model system for studying positive-strand RNA virus replication; null mutation confers sensitivity to tunicamycin and DTT; Required for replication of Brome mosaic virus (BMV) (224 aa)
     
   
  0.814
DET1
Acid phosphatase involved in the non-vesicular transport of sterols in both directions between the endoplasmic reticulum and plasma membrane; deletion confers sensitivity to nickel; Metal-independent, broad-range acid phosphatase. Involved, either directly or indirectly, in the bidirectional transport of sterols between the endoplasmic reticulum and the plasma membrane (334 aa)
     
        0.767
YHB1
Nitric oxide oxidoreductase, flavohemoglobin involved in nitric oxide detoxification; plays a role in the oxidative and nitrosative stress responses; Is involved in NO detoxification in an aerobic process, termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and NAD(P)H to convert NO to nitrate, which protects the fungus from various noxious nitrogen compounds. Therefore, plays a central role in the inducible response to nitrosative stress (399 aa)
       
 
  0.714
VPS34
Phosphatidylinositol 3-kinase responsible for the synthesis of phosphatidylinositol 3-phosphate; forms membrane-associated signal transduction complex with Vps15p to regulate protein sorting; activated by the GTP-bound form of Gpa1p; Phosphatidylinositol 3-kinase required for cytoplasm to vacuole transport (Cvt) and autophagy as a part of the autophagy- specific VPS34 PI3-kinase complex I. This complex is essential to recruit the ATG8-phosphatidylinositol conjugate and the ATG12-ATG5 conjugate to the pre-autophagosomal structure. Also involved in endosome-to-Golgi retrograde transport [...] (875 aa)
       
      0.699
MAS2
Alpha subunit of the mitochondrial processing protease (MPP); essential processing enzyme that cleaves the N-terminal targeting sequences from mitochondrially imported proteins; Cleaves presequences (transit peptides) from mitochondrial protein precursors. The cleavage sites typically contain an arginine at position -2 (in the N-terminal portion) from the scissible peptide bond in addition to other distal basic residues, and an aromatic residue at position +1 (482 aa)
