Asymmetric Unit(hide GO term definitions)
Chain A,B,C,D   (ZNRF3_MOUSE | Q5SSZ7)
molecular function
    GO:0005109    frizzled binding    Interacting selectively and non-covalently with the frizzled (fz) receptor.
    GO:0016874    ligase activity    Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0004842    ubiquitin-protein transferase activity    Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0038018    Wnt receptor catabolic process    The chemical reactions and pathways resulting in the breakdown of a Wnt receptor. Internalized Wnt receptors can be recycled to the plasma membrane or sorted to lysosomes for protein degradation.
    GO:0016055    Wnt signaling pathway    The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell and ending with a change in cell state.
    GO:0060071    Wnt signaling pathway, planar cell polarity pathway    The series of molecular signals initiated by binding of a Wnt protein to a receptor on the surface of the target cell where activated receptors signal via downstream effectors including C-Jun N-terminal kinase (JNK) to modulate cytoskeletal elements and control cell polarity.
    GO:0060070    canonical Wnt signaling pathway    The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes. In this pathway, the activated receptor signals via downstream effectors that result in the inhibition of beta-catenin phosphorylation, thereby preventing degradation of beta-catenin. Stabilized beta-catenin can then accumulate and travel to the nucleus to trigger changes in transcription of target genes.
    GO:0030178    negative regulation of Wnt signaling pathway    Any process that stops, prevents, or reduces the frequency, rate or extent of the Wnt signaling pathway.
    GO:0090090    negative regulation of canonical Wnt signaling pathway    Any process that decreases the rate, frequency, or extent of the Wnt signaling pathway through beta-catenin, the series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes.
    GO:2000051    negative regulation of non-canonical Wnt signaling pathway    Any process that stops, prevents, or reduces the frequency, rate or extent of non-canonical Wnt signaling pathway.
    GO:0016567    protein ubiquitination    The process in which one or more ubiquitin groups are added to a protein.
    GO:0072089    stem cell proliferation    The multiplication or reproduction of stem cells, resulting in the expansion of a stem cell population. A stem cell is a cell that retains the ability to divide and proliferate throughout life to provide progenitor cells that can differentiate into specialized cells.
    GO:0006511    ubiquitin-dependent protein catabolic process    The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein.
cellular component
    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:0005887    integral component of plasma membrane    The component of the plasma 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.

Chain E,F,G,H   (RSPO1_HUMAN | Q2MKA7)
molecular function
    GO:0001664    G-protein coupled receptor binding    Interacting selectively and non-covalently with a G-protein coupled receptor.
    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: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: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.
biological process
    GO:0016055    Wnt signaling pathway    The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell and ending with a change in cell state.
    GO:0030177    positive regulation of Wnt signaling pathway    Any process that activates or increases the frequency, rate or extent of Wnt signal transduction.
    GO:0090263    positive regulation of canonical Wnt signaling pathway    Any process that increases the rate, frequency, or extent of the Wnt signaling pathway through beta-catenin, the series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes.
    GO:0001934    positive regulation of protein phosphorylation    Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to amino acids within a protein.
    GO:0002090    regulation of receptor internalization    Any process that modulates the frequency, rate or extent of receptor internalization.
    GO:0050896    response to stimulus    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism.
cellular component
    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:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
