Chain A   (PAG_BACAN | P13423)
molecular function
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0043409    negative regulation of MAPK cascade    Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction mediated by the MAPKKK cascade.
    GO:0010629    negative regulation of gene expression    Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
    GO:0001933    negative regulation of protein phosphorylation    Any process that stops, prevents or reduces the rate of addition of phosphate groups to amino acids within a protein.
    GO:0000122    negative regulation of transcription from RNA polymerase II promoter    Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
    GO:0044533    positive regulation of apoptotic process in other organism    Any process in which an organism activates, maintains or increases the frequency, rate or extent of programmed cell death by apoptosis in a second organism.
    GO:0097300    programmed necrotic cell death    A necrotic cell death process that results from the activation of endogenous cellular processes, such as signaling involving death domain receptors or Toll-like receptors.
    GO:0051260    protein homooligomerization    The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.
    GO:0035897    proteolysis in other organism    The chemical reactions and pathways performed by an organism resulting in the hydrolysis of proteins in another organism by cleavage of their peptide bonds.
    GO:1903140    regulation of establishment of endothelial barrier    Any process that modulates the frequency, rate or extent of establishment of endothelial barrier.
    GO:0061136    regulation of proteasomal protein catabolic process    Any process that modulates the rate, frequency, or extent of the chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds that is mediated by the proteasome.
cellular component
    GO:0010008    endosome membrane    The lipid bilayer surrounding an endosome.
    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:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
