The cell cycle process in which the dynamic reorganization of telomeres occurs in early meiotic prophase, during which meiotic chromosome ends are gathered in a bouquet arrangement at the inner surface of the nuclear envelope proximal to the spindle pole body. This plays an important role in progression through meiosis and precedes synapsis.

Enables the transmembrane transfer of a chloride 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.

Enables the facilitated diffusion of a chloride (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

Enables the transmembrane transfer of an anion by a voltage-gated channel. An anion is a negatively charged ion. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.

Enables the transmembrane transfer of a sodium 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.

Enables the facilitated diffusion of a sodium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

Catalysis of the covalent insertion of double-stranded retroviral DNA into host DNA. Proceeds by an endonucleolytic cleavage at each 3'-OH extremity of the viral genome, named 3'-processing, followed by a strand transfer reaction leading to the insertion of the processed viral DNA into the target DNA by a trans-esterification mechanism.

Catalysis of the integration of one DNA segment into another.

Enables the facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

The catalysis of the removal of two di- or tri-nucleotides from each 3' end of double-stranded viral DNA, exposing recessed 3' hydroxyls.

Catalysis of the hydrolysis of ester linkages within deoxyribonucleic acid by creating internal breaks.

OBSOLETE. Catalysis of the covalent insertion of processed 3'-viral DNA ends into host chromosomal DNA by a trans-esterification reaction.

The insertion into a host genome of viral DNA, usually by the action of an integrase enzyme. Once integrated, the provirus persists in the host cell and serves as a template for the transcription of viral genes and replication of the viral genome, leading to the production of new viruses.

A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.

A process in which a host organism stops, prevents or reduces the frequency, rate or extent of viral genome replication.

A process in which a host organism stops, prevents or reduces the frequency, rate or extent of a process being mediated by a virus with which it is infected.

OBSOLETE. (Was not defined before being made obsolete).

OBSOLETE. (Was not defined before being made obsolete).

The process in which an antigen-presenting cell expresses antigen (peptide or lipid) on its cell surface in association with an MHC protein complex.
