A horn-shaped dinoflagellate antapex found in thecate species.

The neurotransmitter-gated ion channel clustering process in which glutamate receptors are localized to distinct domains in the cell membrane.

The receptor clustering process in which neurotransmitter-gated ion channels are localized to distinct domains in the cell membrane.

The process in which the association between sister chromatids of a replicated chromosome is maintained as chromosomes condense, attach to the spindle in a bipolar orientation, and congress to the metaphase plate during a meiotic cell cycle.

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 diethyl maleate 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 a diethyl maleate stimulus.

Any nucleotide phosphorylation that is involved in DNA repair.

The process of introducing one or more phosphate groups into a nucleotide to produce a phosphorylated nucleoside.

Binding to calcidiol.

Any process that modulates the frequency, rate or extent of meiotic spindle elongation.

Any process that modulates the frequency, rate or extent of the cell cycle process in which the distance is lengthened between poles of the spindle.

A cell surface furrow that wraps around a dinoflagellate cell; the transverse flagellum lies in it.

A cell surface furrow that occurs on the ventral side of a dinoflagellate cell. It partially houses the longitudinal flagellum. The sulcus intersects with the cingulum on the ventral side of a dinoflagellate cell.

The part of a dinoflagellate cell above the cingulum; also referred to as the anterior portion of a dinoflagellate cell. It is separated from the hypocone by the cingulum.

The part of a dinoflagellate cell below the cingulum; also referred to as the posterior portion of a dinoflagellate cell. It is separated from the epicone by the cingulum.

The process in which an organism effects a change in the type IV pilus-dependent motility of a symbiont organism (i.e. the controlled movement of a bacterial cell which is dependent on the presence of type IV pili, and which includes social gliding motility and twitching motility). The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction.

Any process in which an organism activates, maintains or increases the frequency, rate or extent of the type IV pilus-dependent motility of a symbiont organism (i.e. the controlled movement of a bacterial cell which is dependent on the presence of type IV pili, and which includes social gliding motility and twitching motility). The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction.

A dinoflagellate sulcus that extends all the way to the posterior end of the cell (also known as antapex). The presence of a sulcal notch makes the dinoflagellate hypocone appear bilobed.
