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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

rcnAMembrane protein conferring nickel and cobalt resistance; Efflux system for nickel and cobalt. (274 aa)    
Predicted Functional Partners:
rcnR
Transcriptional repressor of rcnA; Repressor of rcnA expression. Acts by binding specifically to the rcnA promoter in the absence of nickel and cobalt. In the presence of one of these metals, it has a weaker affinity for rcnA promoter. Belongs to the FrmR/RcnR family.
 
  
 0.994
rcnB
Periplasmic modulator of Ni and Co efflux; Influences nickel and cobalt homeostasis. May act by modulating RcnA-mediated export of these ions to avoid excess efflux. Not involved in nickel import and does not bind nickel or cobalt ions directly; Belongs to the RcnB family.
  
  
 0.937
nikR
Transcriptional repressor, Ni-binding; Transcriptional repressor of the nikABCDE operon. Is active in the presence of excessive concentrations of intracellular nickel; Belongs to the transcriptional regulatory CopG/NikR family.
  
   
 0.912
zntA
Zinc, cobalt and lead efflux system; Confers resistance to zinc, cadmium and lead. Couples the hydrolysis of ATP with the export of zinc, cadmium or lead, with highest activity when the metals are present as metal-thiolate complexes. Can also bind nickel, copper, cobalt and mercury. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily.
     
 0.784
nikA
Nickel/heme ABC transporter periplasmic binding protein; Involved in a nickel transport system, probably represents the nickel binder.
  
   
 0.779
arsR
Arsenical resistance operon transcriptional repressor; Transcriptional repressor for the arsEFG operon. ArsE is a trans-acting regulatory protein which controls its own expression. The repressive effect of ArsE is alleviated by oxyions of +III oxidation state of arsenic, antimony, and bismuth, as well as arsenate (As(V)) (By similarity).
      
 0.623
zntR
zntA gene transcriptional activator; Zinc-responsive transcriptional regulator of zntA.
      
 0.597
znuA
Zinc ABC transporter periplasmic binding protein; Involved in the high-affinity zinc uptake transport system.
     
 0.554
zitB
Zinc efflux system; Involved in zinc efflux across the cytoplasmic membrane, thus reducing zinc accumulation in the cytoplasm and rendering bacteria more resistant to zinc. It may contribute to zinc homeostasis at low concentrations of zinc, whereas ZntA is required for growth at more toxic concentrations; Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family. SLC30A subfamily.
     
 0.539
fieF
Ferrous iron and zinc transporter; Iron-efflux transporter responsible for iron detoxification. Also able to transport Zn(2+) in a proton-dependent manner. Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family. FieF subfamily.
      
 0.529
