STRINGSTRING
PUT4 protein (Saccharomyces cerevisiae) - STRING interaction network
"PUT4" - Proline permease, required for high-affinity transport of proline 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

PUT4Proline permease, required for high-affinity transport of proline; also transports the toxic proline analog azetidine-2-carboxylate (AzC); PUT4 transcription is repressed in ammonia-grown cells; Required for high-affinity proline transport. May be responsible for proline recognition and probably also for proline translocation across the plasma membrane. Also function as non- specific GABA permease. Can also transport alanine and glycine (627 aa)    
Predicted Functional Partners:
DUR1,2
Urea amidolyase, contains both urea carboxylase and allophanate hydrolase activities, degrades urea to CO2 and NH3; expression sensitive to nitrogen catabolite repression and induced by allophanate, an intermediate in allantoin degradation; Hydrolysis of urea to ammonia and CO(2) (1835 aa)
   
   
  0.839
SCT1
Glycerol 3-phosphate/dihydroxyacetone phosphate dual substrate-specific sn-1 acyltransferase of the glycerolipid biosynthesis pathway, prefers 16-carbon fatty acids, similar to Gpt2p, gene is constitutively transcribed; G-3-P/dihydroxyacetone phosphate dual substrate-specific sn-1 acyltransferase (759 aa)
           
  0.829
HNM1
Choline/ethanolamine transporter; involved in the uptake of nitrogen mustard and the uptake of glycine betaine during hypersaline stress; co-regulated with phospholipid biosynthetic genes and negatively regulated by choline and myo-inositol; Sole choline transporter in yeast (563 aa)
           
  0.823
UGA4
Permease that serves as a gamma-aminobutyrate (GABA) transport protein involved in the utilization of GABA as a nitrogen source; catalyzes the transport of putrescine and delta-aminolevulinic acid (ALA); localized to the vacuolar membrane; Required for high-affinity, high-specificity GABA transport. Also transports putrescine (571 aa)
           
  0.821
LST4
Protein possibly involved in a post-Golgi secretory pathway; required for the transport of nitrogen-regulated amino acid permease Gap1p from the Golgi to the cell surface; Involved in extracellular amino acid uptake. Required for the trafficking of the GAP1 nitrogen-regulated general amino acid permease from the Golgi to the plasma membrane (828 aa)
           
  0.820
LST7
Protein possibly involved in a post-Golgi secretory pathway; required for the transport of nitrogen-regulated amino acid permease Gap1p from the Golgi to the cell surface; Required for the nitrogen-regulated transport of amino acid permeases GAP1 and PUT4 from the Golgi to the cell surface (242 aa)
           
  0.820
PUT2
Delta-1-pyrroline-5-carboxylate dehydrogenase, nuclear-encoded mitochondrial protein involved in utilization of proline as sole nitrogen source; deficiency of the human homolog causes HPII, an autosomal recessive inborn error of metabolism (575 aa)
       
  0.803
GLN3
Transcriptional activator of genes regulated by nitrogen catabolite repression (NCR), localization and activity regulated by quality of nitrogen source; Positive nitrogen regulatory protein. Required for the activation of transcription of a number of genes (including the allantoin pathway genes) in response to the replacement of glutamine by glutamate as source of nitrogen. Binds the nitrogen upstream activation sequence of GLN1, the gene encoding glutamine synthetase. URE2 may catalytically inactivate GLN3 in response to an increase in the intracellular concentration of glutamine (730 aa)
           
  0.784
SEC13
Component of the Nup84 nuclear pore sub-complex, the Sec13p-Sec31p complex of the COPII vesicle coat, and the SEA (Seh1-associated) complex; required for vesicle formation in ER to Golgi transport and nuclear pore complex organization; the Nup84 sub /.../x has a role in transcription elongation; Functions as a component of the nuclear pore complex (NPC) and the COPII coat. It is one of 5 proteins constituting the COPII coat, which is involved in anterograde (ER to Golgi) double- membrane transport vesicle formation. First the small GTPase SAR1, activated by and binding to the integral [...] (297 aa)
       
 
  0.758
PUT1
Proline oxidase, nuclear-encoded mitochondrial protein involved in utilization of proline as sole nitrogen source; PUT1 transcription is induced by Put3p in the presence of proline and the absence of a preferred nitrogen source; Converts proline to delta-1-pyrroline-5-carboxylate (476 aa)
