STRINGSTRING
TNA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"TNA1" - High affinity nicotinic acid plasma membrane permease, responsible for uptake of low levels of nicotinic acid 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

TNA1High affinity nicotinic acid plasma membrane permease, responsible for uptake of low levels of nicotinic acid; expression of the gene increases in the absence of extracellular nicotinic acid or para-aminobenzoate (PABA); Involved in the uptake of nicotinic acid (534 aa)    
Predicted Functional Partners:
QRI1
UDP-N-acetylglucosamine pyrophosphorylase, catalyzes the formation of UDP-N-acetylglucosamine (UDP-GlcNAc), which is important in cell wall biosynthesis, protein N-glycosylation, and GPI anchor biosynthesis (477 aa)
       
      0.905
NMA1
Nicotinic acid mononucleotide adenylyltransferase, involved in pathways of NAD biosynthesis, including the de novo, NAD(+) salvage, and nicotinamide riboside salvage pathways; Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate to form deamido- NAD(+) (NaAD). Key enzyme in both de novo and salvage pathways for NAD(+) biosynthesis. Predominantly acts in the salvage pathways via NMN (401 aa)
         
  0.813
NMA2
Nicotinic acid mononucleotide adenylyltransferase, involved in de novo and salvage synthesis of NAD(+); Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP (PubMed-12597897). Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate to form deamido-NAD(+) (NaAD). Key enzyme in both de novo and salvage pathways for NAD(+) biosynthesis (By similarity). Predominantly acts in the salvage pathways via NMN (PubMed-11884393) (395 aa)
         
  0.812
NRT1
High-affinity nicotinamide riboside transporter; also transports thiamine with low affinity; shares sequence similarity with Thi7p and Thi72p; proposed to be involved in 5-fluorocytosine sensitivity; High-affinity pH-dependent nicotinamide riboside transporter which also transports thiamine with low affinity. Involved in 5-fluorocytosine sensitivity (598 aa)
     
   
  0.721
PNC1
Nicotinamidase that converts nicotinamide to nicotinic acid as part of the NAD(+) salvage pathway, required for life span extension by calorie restriction; PNC1 expression responds to all known stimuli that extend replicative life span; Catalyzes the deamidation of nicotinamide, an early step in the NAD(+) salvage pathway. Positively regulates SIR2-mediated silencing and longevity by preventing the accumulation of intracellular nicotinamide, an inhibitor of SIR2, during times of stress. Acts also on nicotinyl hydroxamate (216 aa)
         
  0.704
URH1
Uridine nucleosidase (uridine-cytidine N-ribohydrolase), cleaves N-glycosidic bonds in nucleosides; involved in the pyrimidine salvage and nicotinamide riboside salvage pathways; Also acts on cytidine (340 aa)
         
  0.693
BNA1
3-hydroxyanthranilic acid dioxygenase, required for the de novo biosynthesis of NAD from tryptophan via kynurenine; expression regulated by Hst1p; Catalyzes the oxidative ring opening of 3- hydroxyanthranilate to 2-amino-3-carboxymuconate semialdehyde, which spontaneously cyclizes to quinolinate (177 aa)
     
 
  0.689
SNQ2
Plasma membrane ATP-binding cassette (ABC) transporter, multidrug transporter involved in multidrug resistance and resistance to singlet oxygen species; Could be an ATP-dependent permease. Confers hyper- resistance to the mutagens 4-nitroquinoline-N-oxide (4-NQO) and triaziquone, as well as to the chemicals sulphomethuron methyl phenanthroline when present in multiple copies. Exhibits nucleoside triphosphatase activity (1501 aa)
 
 
  0.674
PDR11
ATP-binding cassette (ABC) transporter, multidrug transporter involved in multiple drug resistance; mediates sterol uptake when sterol biosynthesis is compromisedregulated by Pdr1p; required for anaerobic growth; Transporter involved in the uptake of sterol (1411 aa)
   
 
  0.657
PDR15
Plasma membrane ATP binding cassette (ABC) transporter, multidrug transporter and general stress response factor implicated in cellular detoxification; regulated by Pdr1p, Pdr3p and Pdr8p; promoter contains a PDR responsive element (1529 aa)
