NMR Structure(hide GO term definitions)
Chain A   (BLK_MOUSE | P16277)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0016301    kinase activity    Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
    GO:0004715    non-membrane spanning protein tyrosine kinase activity    Catalysis of the reaction: ATP + protein L-tyrosine = ADP + protein L-tyrosine phosphate by a non-membrane spanning protein.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    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).
    GO:0004672    protein kinase activity    Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP.
    GO:0004713    protein tyrosine kinase activity    Catalysis of the reaction: ATP + a protein tyrosine = ADP + protein tyrosine phosphate.
    GO:0005102    receptor binding    Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0050853    B cell receptor signaling pathway    A series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell.
    GO:0030154    cell differentiation    The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state.
    GO:0007010    cytoskeleton organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures.
    GO:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
    GO:0043066    negative regulation of apoptotic process    Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.
    GO:0038083    peptidyl-tyrosine autophosphorylation    The phosphorylation by a protein of one or more of its own tyrosine amino acid residues, or a tyrosine residue on an identical protein.
    GO:0016310    phosphorylation    The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
    GO:0032024    positive regulation of insulin secretion    Any process that activates or increases the frequency, rate or extent of the regulated release of insulin.
    GO:0006468    protein phosphorylation    The process of introducing a phosphate group on to a protein.
    GO:0042127    regulation of cell proliferation    Any process that modulates the frequency, rate or extent of cell proliferation.
    GO:0050764    regulation of phagocytosis    Any process that modulates the frequency, rate or extent of phagocytosis, the process in which phagocytes engulf external particulate material.
    GO:0071801    regulation of podosome assembly    Any process that modulates the frequency, rate or extent of podosome assembly.
    GO:0007169    transmembrane receptor protein tyrosine kinase signaling pathway    A series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell where the receptor possesses tyrosine kinase activity, and ending with regulation of a downstream cellular process, e.g. transcription.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0031234    extrinsic component of cytoplasmic side of plasma membrane    The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to its cytoplasmic surface, but not integrated into the hydrophobic region.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    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.
