Chain A   (AGRIN_CHICK | P31696)
molecular function
    GO:0030548    acetylcholine receptor regulator activity    Interacting (directly or indirectly) with acetylcholine receptors such that the proportion of receptors in the active form is changed.
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0035374    chondroitin sulfate binding    Interacting selectively and non-covalently with chondroitin sulfate, a glycosaminoglycan made up of two alternating monosaccharides: D-glucuronic acid (GlcA) and N-acetyl-D-galactosamine (GalNAc).
    GO:0002162    dystroglycan binding    Interacting selectively and non-covalently with dystroglycan. Dystroglycan is glycoprotein found in non-muscle tissues as well as in muscle tissues, often in association with dystrophin. The native dystroglycan cleaved into two non-covalently associated subunits, alpha (N-terminal) and beta (C-terminal).
    GO:0043395    heparan sulfate proteoglycan binding    Interacting selectively and non-covalently with a heparan sulfate proteoglycan, any proteoglycan containing heparan sulfate as the glycosaminoglycan carbohydrate unit.
    GO:0008201    heparin binding    Interacting selectively and non-covalently with heparin, any member of a group of glycosaminoglycans found mainly as an intracellular component of mast cells and which consist predominantly of alternating alpha-(1->4)-linked D-galactose and N-acetyl-D-glucosamine-6-sulfate residues.
    GO:0043236    laminin binding    Interacting selectively and non-covalently with laminins, glycoproteins that are major constituents of the basement membrane of cells.
    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).
    GO:0033691    sialic acid binding    Interacting selectively and non-covalently with sialic acid, any of a variety of N- or O- substituted derivatives of neuraminic acid, a nine carbon monosaccharide. Sialic acids often occur in polysaccharides, glycoproteins, and glycolipids in animals and bacteria.
    GO:0030297    transmembrane receptor protein tyrosine kinase activator activity    Binds to and increases the activity of a transmembrane receptor protein tyrosine kinase.
biological process
    GO:0007213    G-protein coupled acetylcholine receptor signaling pathway    Any series of molecular signals initiated by an acetylcholine receptor on the surface of the target cell binding to one of its physiological ligands, and proceeding with the activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction and ends with regulation of a downstream cellular process, e.g. transcription.
    GO:0007171    activation of transmembrane receptor protein tyrosine kinase activity    Any process that initiates the activity of the inactive transmembrane receptor protein tyrosine kinase activity.
    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:0030198    extracellular matrix organization    A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.
    GO:0007275    multicellular organism development    The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0051491    positive regulation of filopodium assembly    Any process that activates or increases the frequency, rate or extent of the assembly of a filopodium, a thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone.
    GO:0045887    positive regulation of synaptic growth at neuromuscular junction    Any process that activates or increases the frequency, rate or extent of synaptic growth at neuromuscular junction.
    GO:0045944    positive regulation of transcription from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0043113    receptor clustering    The receptor metabolic process that results in grouping of a set of receptors at a cellular location, often to amplify the sensitivity of a signaling response.
    GO:0099601    regulation of neurotransmitter receptor activity    Any process that modulates the frequency, rate or extent of neurotransmitter receptor activity. Modulation may be via an effect on ligand affinity, or effector funtion such as ion selectivity or pore opening/closing in ionotropic receptors.
cellular component
    GO:0005605    basal lamina    A thin sheet of proteoglycans and glycoproteins, especially laminin, secreted by cells as an extracellular matrix.
    GO:0030054    cell junction    A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix.
    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: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.
    GO:0005578    proteinaceous extracellular matrix    A layer consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that forms a sheet underlying or overlying cells such as endothelial and epithelial cells. The proteins are secreted by cells in the vicinity. An example of this component is found in Mus musculus.
    GO:0045202    synapse    The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
