"NMNAT3" - Nicotinamide/nicotinic acid mononucleotide adenylyltransferase 3 in Homo sapiens
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

NMNAT3Nicotinamide/nicotinic acid mononucleotide adenylyltransferase 3; Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate with the same efficiency. Can use triazofurin monophosphate (TrMP) as substrate. Can also use GTP and ITP as nucleotide donors. Also catalyzes the reverse reaction, i.e. the pyrophosphorolytic cleavage of NAD(+). For the pyrophosphorolytic activity, can use NAD(+), NADH, NaAD, nicotinic acid adenine dinucleotide phosphate (NHD), nicotinamide guanine dinucleo [...] (215 aa)    
Predicted Functional Partners:
NADSYN1
Glutamine-dependent NAD(+) synthetase; NAD synthetase 1; In the C-terminal section; belongs to the NAD synthetase family (706 aa)
   
 
  0.981
NADK
NAD kinase; Belongs to the NAD kinase family (591 aa)
   
 
  0.974
NAPRT
Nicotinate phosphoribosyltransferase; Catalyzes the conversion of nicotinic acid (NA) to NA mononucleotide (NaMN). Essential for NA to increase cellular NAD levels and prevent oxidative stress of the cells; Belongs to the NAPRTase family (538 aa)
   
 
  0.973
NAMPT
Nicotinamide phosphoribosyltransferase; Catalyzes the condensation of nicotinamide with 5- phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, an intermediate in the biosynthesis of NAD. It is the rate limiting component in the mammalian NAD biosynthesis pathway. The secreted form behaves both as a cytokine with immunomodulating properties and an adipokine with anti-diabetic properties, it has no enzymatic activity, partly because of lack of activation by ATP, which has a low level in extracellular space and plasma. Plays a role in the modulation of circadian clock fun [...] (491 aa)
   
 
  0.971
NMRK1
Nicotinamide riboside kinase 1; Catalyzes the phosphorylation of nicotinamide riboside (NR) and nicotinic acid riboside (NaR) to form nicotinamide mononucleotide (NMN) and nicotinic acid mononucleotide (NaMN). The enzyme also phosphorylates the antitumor drugs tiazofurin and 3- deazaguanosine; Belongs to the uridine kinase family. NRK subfamily (199 aa)
   
 
  0.969
QPRT
Nicotinate-nucleotide pyrophosphorylase [carboxylating]; Involved in the catabolism of quinolinic acid (QA); Belongs to the NadC/ModD family (297 aa)
       
  0.963
NMRK2
Nicotinamide riboside kinase 2; Catalyzes the phosphorylation of nicotinamide riboside (NR) and nicotinic acid riboside (NaR) to form nicotinamide mononucleotide (NMN) and nicotinic acid mononucleotide (NaMN). Reduces laminin matrix deposition and cell adhesion to laminin, but not to fibronectin. Involved in the regulation of PXN at the protein level and of PXN tyrosine phosphorylation. May play a role in the regulation of terminal myogenesis; Belongs to the uridine kinase family. NRK subfamily (235 aa)
   
 
  0.954
NNT
NAD(P) transhydrogenase, mitochondrial; The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane. May play a role in reactive oxygen species (ROS) detoxification in the adrenal gland; In the N-terminal section; belongs to the AlaDH/PNT family (1086 aa)
     
 
  0.945
NADK2
NAD kinase 2, mitochondrial; Mitochondrial NAD(+) kinase that phosphorylates NAD(+) to yield NADP(+). Can use both ATP or inorganic polyphosphate as the phosphoryl donor. Also has weak NADH kinase activity in vitro; however NADH kinase activity is much weaker than the NAD(+) kinase activity and may not be relevant in vivo (442 aa)
         
  0.938
BST1
ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 2; Synthesizes the second messagers cyclic ADP-ribose and nicotinate-adenine dinucleotide phosphate, the former a second messenger that elicits calcium release from intracellular stores. May be involved in pre-B-cell growth; Belongs to the ADP-ribosyl cyclase family (318 aa)
