molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0030165    PDZ domain binding    Interacting selectively and non-covalently with a PDZ domain of a protein, a domain found in diverse signaling proteins.
    GO:0005388    calcium-transporting ATPase activity    Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + Ca2+(cis) = ADP + phosphate + Ca2+(trans).
    GO:0005516    calmodulin binding    Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
    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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0050998    nitric-oxide synthase binding    Interacting selectively and non-covalently with the enzyme nitric-oxide synthase.
    GO:0036487    nitric-oxide synthase inhibitor activity    Interacts with, and stops, prevents or reduces the activity of nitric oxide synthase.
    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:0030346    protein phosphatase 2B binding    Interacting selectively and non-covalently with the enzyme protein phosphatase 2B.
    GO:0097110    scaffold protein binding    Interacting selectively and non-covalently with a scaffold protein. Scaffold proteins are crucial regulators of many key signaling pathways. Although not strictly defined in function, they are known to interact and/or bind with multiple members of a signaling pathway, tethering them into complexes.
    GO:0017080    sodium channel regulator activity    Modulates the activity of a sodium channel.
biological process
    GO:1901660    calcium ion export    The directed movement of calcium ion out of a cell or organelle.
    GO:0098703    calcium ion import across plasma membrane    The directed movement of calcium ions from outside of a cell, across the plasma membrane and into the cytosol.
    GO:0097553    calcium ion transmembrane import into cytosol    A process in which a calcium ion is transported from one side of a membrane to the other into the cytosol by means of some agent such as a transporter or pore.
    GO:0070588    calcium ion transmembrane transport    A process in which a calcium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
    GO:0006816    calcium ion transport    The directed movement of calcium (Ca) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0006874    cellular calcium ion homeostasis    Any process involved in the maintenance of an internal steady state of calcium ions at the level of a cell.
    GO:0071872    cellular response to epinephrine stimulus    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an epinephrine stimulus. Epinephrine is a catecholamine that has the formula C9H13NO3; it is secreted by the adrenal medulla to act as a hormone, and released by certain neurons to act as a neurotransmitter active in the central nervous system.
    GO:0030317    flagellated sperm motility    Any process involved in the controlled movement of a flagellated sperm cell.

    GO:0043234    protein complex    A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.
    GO:0042383    sarcolemma    The outer membrane of a muscle cell, consisting of the plasma membrane, a covering basement membrane (about 100 nm thick and sometimes common to more than one fiber), and the associated loose network of collagen fibers.
    GO:0036126    sperm flagellum    A microtubule-based flagellum (or cilium) that is part of a sperm, a mature male germ cell that develops from a spermatid.
    GO:0097228    sperm principal piece    The segment of the sperm flagellum where the mitochondrial sheath ends, and the outer dense fibers (ODFs) associated with outer axonemal doublets 3 and 8 are replaced by the 2 longitudinal columns of the fibrous sheath (FS) which run the length of the principal piece and are stabilized by circumferential ribs. The principal piece makes up ~2/3 of the length of the sperm flagellum and is defined by the presence of the FS and of only 7 (rather than 9) ODFs which taper and then terminate near the distal end of the principal piece.
