Chain A,B   (CACB3_RAT | P54287)
molecular function
    GO:0005262    calcium channel activity    Enables the facilitated diffusion of a calcium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
    GO:0008331    high voltage-gated calcium channel activity    Enables the transmembrane transfer of a calcium ion by a high voltage-gated channel. A high voltage-gated channel is a channel whose open state is dependent on high voltage across the membrane in which it is embedded.
    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:0019901    protein kinase binding    Interacting selectively and non-covalently with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate.
    GO:0005245    voltage-gated calcium channel activity    Enables the transmembrane transfer of a calcium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
    GO:0005244    voltage-gated ion channel activity    Enables the transmembrane transfer of an ion by a voltage-gated channel. An ion is an atom or group of atoms carrying an electric charge by virtue of having gained or lost one or more electrons. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
biological process
    GO:0050852    T cell receptor signaling pathway    A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.
    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:0061577    calcium ion transmembrane transport via high voltage-gated calcium channel    A process in which a calcium ion is transported from one side of a membrane to the other by means of a high voltage-gated calcium channel.
    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:0060402    calcium ion transport into cytosol    The directed movement of calcium ions (Ca2+) into the cytosol.
    GO:0007268    chemical synaptic transmission    The vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse.
