STRINGSTRING
STRING protein interaction network
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

radADNA repair protein; DNA-dependent ATPase involved in processing of recombination intermediates, plays a role in repairing DNA breaks. Stimulates the branch migration of RecA-mediated strand transfer reactions, allowing the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA in the presence of ADP but not other nucleotides, has ATPase activity that is stimulated by ssDNA and various branched DNA structures, but inhibited by SSB. Does not have RecA's homology-searching function. (458 aa)    
Predicted Functional Partners:
disA
Diadenylate cyclase; Participates in a DNA-damage check-point that is active prior to asymmetric division when DNA is damaged. Forms globular foci that rapidly scan along the chromosomes during sporulation, searching for lesions. Its ability to scan through the chromosome rapidly is due to its non-specific DNA- binding. When a lesion is present, DisA pauses at the lesion site. This triggers a cellular response that culminates in a temporary block in sporulation initiation. It is required, at least partially, to inhibit the activity of the transcription factor spo0A, which controls, amo [...]

recA
Multifunctional SOS repair factor; Multifunctional protein involved in homologous recombination, DNA repair and competence. Can catalyze the hydrolysis of (d)ATP in the presence of single-stranded DNA; prefers dATP at least in vitro, catalyzes the dATP-dependent uptake of single- stranded DNA by duplex DNA, and the dATP-dependent hybridization of homologous single-stranded DNAs (strand exchange). RecA-ATP cannot catalyze homologous DNA strand exchange; SsbA and DprA activate strand exchange by RecA-ATP. It interacts with LexA causing its activation and leading to its autocatalytic clea [...]

recX
Regulatory protein RecX; Modulates RecA activity; Belongs to the RecX family.
 
  
 0.965
mcsB
Protein tyrosine kinase; Catalyzes the specific phosphorylation of arginine residues in a large number of proteins. Is part of the bacterial stress response system, where it is involved in regulating the global heat shock repressor CtsR; phosphorylates arginine residues in the winged helix- turn-helix domain of CtsR, thereby preventing its binding to DNA and consequently inducing the expression of repressed genes. The transcriptional repressor HrcA, the chaperone GroEL, the unfoldase ClpC, together with several ribosomal subunits, represent other physiological targets of McsB under str [...]

clpC
Class III stress response-related ATPase, AAA+ superfamily; Competence gene repressor; required for cell growth at high temperature. Negative regulator of comK expression. May interact with MecA to negatively regulate comK; Belongs to the ClpA/ClpB family. ClpC subfamily.
  
  
 0.902
yacL
Putative membrane protein; An RNase; In the central section; belongs to the PINc/VapC protein family.
  
  
 0.901
recG
Branch migrating ATP-dependent DNA helicase involved in DNA recombination and repair; Critical role in recombination and DNA repair. Helps process Holliday junction intermediates to mature products by catalyzing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3'- to 5'- polarity. Unwinds branched duplex DNA (Y- DNA) (By similarity); Belongs to the helicase family. RecG subfamily.

mcsA
Activator of protein kinase McsB; Activates the phosphorylation activity of the protein- arginine kinase McsB. Is required for the delocalization of competence proteins from the cell poles.
  
  
 0.884
ispD
2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase, nonmevalonate isoprenoid pathway; Catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D- erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP).
  
  
 0.845
recN
Factor for double strand breaks DNA repair and genetic recombination; Involved in recombinational repair of damaged DNA. Seems to be the first protein recruited to repair centers, foci that are the site of double-strand DNA break(s), followed by RecO and then RecF.
