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
Your Input:
ompCOuter membrane porin protein C; Forms pores that allow passive diffusion of small molecules across the outer membrane. (Microbial infection) A mixed OmpC-OmpF heterotrimer is the outer membrane receptor for toxin CdiA-EC536; polymorphisms in extracellular loops 4 and 5 of OmpC confer susceptibility to CdiA- EC536-mediated toxicity; Belongs to the Gram-negative porin family. (367 aa)
btuBVitamin B12/cobalamin outer membrane transporter; Involved in the active translocation of vitamin B12 (cyanocobalamin) across the outer membrane to the periplasmic space. It derives its energy for transport by interacting with the trans- periplasmic membrane protein TonB. Is also a receptor for bacteriophages BF23 and C1, and for A and E colicins. (614 aa)
lamBMaltose outer membrane porin (maltoporin); Involved in the transport of maltose and maltodextrins, indispensable for translocation of dextrins containing more than three glucosyl moieties. A hydrophobic path ('greasy slide') of aromatic residues serves to guide and select the sugars for transport through the channel. Also acts as a receptor for several bacteriophages including lambda. (446 aa)
tolBPeriplasmic protein; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. TolB occupies a key intermediary position in the Tol-Pal system because it communicates directly with both membrane-embedded components, Pal in the outer membrane and TolA in the inner membrane. Is also involved in the uptake of some colicins A. The Tol-Pal system is also required for polar localization of chemoreceptors clusters. (430 aa)
ompFOuter membrane porin 1a (Ia;b;F); Forms pores that allow passive diffusion of small molecules across the outer membrane. (Microbial infection) A mixed OmpC-OmpF heterotrimer is the outer membrane receptor for toxin CdiA-EC536; polymorphisms in extracellular loops 4 and 5 of OmpC confer susceptibility to CdiA- EC536-mediated toxicity; Belongs to the Gram-negative porin family. (362 aa)
cirAColicin IA outer membrane receptor and translocator; Not yet known. Postulated to participate in iron transport. Outer membrane receptor for colicins IA and IB. (663 aa)
