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

iniAIsoniazid inductible gene protein IniA; Participates in the development of tolerance to both isoniazid and ethambutol. May function through a MDR-pump like mechanism, although it does not appear to directly transport isoniazid from the cell. (640 aa)    
Predicted Functional Partners:
iniC
Rv0343, (MTCY13E10.03), len: 493 aa. IniC,isoniazid-inducible gene, (see citations below). Shows slight similarity to P40983|YOR6_THER8 hypothetical protein (402 aa), FASTA scores: opt: 196, E(): 2.6e-05, (25.9% identity in 228 aa overlap). Also some similarity to upstream ORF Rv0342|iniA. Contains (PS00017) ATP/GTP-binding site motif A (P-loop). Note that the iniA gene is also induced by the antibiotic ethambutol, an agent that inhibits cell wall biosynthesis by a mechanism that is distinct from isoniazid.

iniB
Rv0341, (MTCY13E10.01), len: 479 aa. IniB,isoniazid-inducible gene, (see citations below). Protein very Gly-, Ala-rich, similar to cell wall proteins e.g. P27483|GRP_ARATH glycine-rich cell wall structural protein from A.thaliana (338 aa), FASTA scores: opt: 532, E(): 5.2e-13, (39.3% identity in 321 aa overlap). MEME-mast analysis shows similarity to product of upstream gene,Rv0340.
