Chain A   (PHP14_HUMAN | Q9NRX4)
molecular function
    GO:0019855    calcium channel inhibitor activity    Stops, prevents, or reduces the activity of a calcium channel.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0044325    ion channel binding    Interacting selectively and non-covalently with one or more specific sites on an ion channel, a protein complex that spans a membrane and forms a water-filled channel across the phospholipid bilayer allowing selective ion transport down its electrochemical gradient.
    GO:0008969    phosphohistidine phosphatase activity    Catalysis of the reaction: phosphohistidine + H2O = histidine + phosphate.
    GO:0004721    phosphoprotein phosphatase activity    Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity.
biological process
    GO:2000984    negative regulation of ATP citrate synthase activity    Any process that stops, prevents or reduces the frequency, rate or extent of ATP citrate synthase activity.
    GO:0050860    negative regulation of T cell receptor signaling pathway    Any process that stops, prevents, or reduces the frequency, rate or extent of signaling pathways initiated by the cross-linking of an antigen receptor on a T cell.
    GO:0051350    negative regulation of lyase activity    Any process that stops or reduces the rate of lyase activity, the catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond.
    GO:0035971    peptidyl-histidine dephosphorylation    The removal of phosphoric residues from peptidyl-O-phospho-L-histidine to form peptidyl-histidine.
    GO:2000147    positive regulation of cell motility    Any process that activates or increases the frequency, rate or extent of cell motility.
    GO:0035774    positive regulation of insulin secretion involved in cellular response to glucose stimulus    Any process that increases the frequency, rate or extent of the regulated release of insulin that contributes to the response of a cell to glucose.
    GO:0006470    protein dephosphorylation    The process of removing one or more phosphoric residues from a protein.
    GO:2000249    regulation of actin cytoskeleton reorganization    Any process that modulates the frequency, rate or extent of actin cytoskeleton reorganization.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    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:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
