Asymmetric Unit(hide GO term definitions)
Chain A   (OMPB1_NEIMB | P30690)
molecular function
    GO:0015288    porin activity    Catalysis of the transfer of substances, sized less than 1000 Da, from one side of the membrane to the other. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria.
biological process
    GO:0002755    MyD88-dependent toll-like receptor signaling pathway    Any series of molecular signals generated as a consequence of binding to a toll-like receptor where the MyD88 adaptor molecule mediates transduction of the signal. Toll-like receptors directly bind pattern motifs from a variety of microbial sources to initiate innate immune response.
    GO:0006811    ion transport    The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0038123    toll-like receptor TLR1:TLR2 signaling pathway    A series of molecular signals initiated by the binding of a heterodimeric TLR1:TLR2 complex to one of it's physiological ligands, followed by transmission of the signal by the activated receptor, and ending with regulation of a downstream cellular process, e.g. transcription.
    GO:0055085    transmembrane transport    The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0009279    cell outer membrane    A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures.
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0046930    pore complex    Any small opening in a membrane that allows the passage of gases and/or liquids.
